RESUMO

Objective: Hepatitis B is a significant infectious disease on a global scale. The implementation of vaccination programs and other preventive measures (e.g., serologic screening of blood donors) leads to lower rates of new infections with the hepatitis B virus. This study aimed to investigate and compare the evolution of hepatitis B incidence, prevalence and mortality rates along with vaccination rates in Türkiye and worldwide between 1990 and 2019. Materials and Methods: The study analyzed open datasets (the Global Burden of Disease and Our World in Data) using descriptive and joinpoint regression analysis to uncover substantial declines in hepatitis B rates from 1990 to 2019, both in Türkiye and globally. Results: The average annual percentage change (AAPC) for incidence rates was -1.81 in Türkiye and -1.481 in the global cohort. For prevalence, the AAPC was -2.5244 in Türkiye and -1.4104 globally. Conclusion: The vaccination rates increased over time and remained at 95% since 2009, suggesting that vaccination efforts effectively reduced the risk of hepatitis B infection among children. This study provided important perspectives for assessing Türkiye's performance in this field and guiding future strategies.

RESUMO

Introduction: Infectious diseases present a substantial worldwide health challenge, yet vaccines have played a crucial role in significantly decreasing illness rates. Despite their effectiveness, global vaccination coverage stands at 85%, leaving a considerable number of infants without routine immunization. Our study seeks to examine the occurrence of delayed primary vaccination and the factors influencing it in Riyadh, Saudi Arabia addressing a critical void in current research. Methodology: A cross-sectional investigation was carried out in the primary care facilities of the first health cluster in Riyadh, Saudi Arabia. Information was gathered utilizing a well-structured questionnaire, modified from a prior study. The study encompassed children aged two years and younger, accompanied by their parents who brought their vaccination cards for the visit. Non-probability convenience sampling was employed for data collection. Subsequently, the data underwent thorough cleaning in Excel (Microsoft Excel) and was subjected to analysis using IBM SPSS 29 (IBM SPSS Statistics 29). Results: The study involved 402 participants, primarily over 12 months old, with a balanced gender distribution. Noteworthy findings indicate a 20.9% prevalence of childhood vaccine delays, with reasons such as high-grade fever (33.3%) and travel (26.2%). Significant associations were found in children aged 6-12 months (25.8%, P = 0.039), families with over four children (31%, P = 0.010), perceptions of vaccine harm (50.0%, P = 0.013), and acknowledgment of neglect (96.4%, P = 0.001). Conclusion: The research illuminates the complex factors influencing childhood vaccine delays in Saudi Arabia. Stressing the significance of personalized interventions, it underscores the necessity to tackle challenges specific to age, parental perspectives, and access issues for improved vaccination outcomes.

RESUMO

Background Despite the success of childhood vaccination in reducing vaccine-preventable diseases (VPDs), vaccine hesitancy remains a significant challenge in several countries, such as Saudi Arabia, both during and beyond the COVID-19 era. Furthermore, the pandemic may have impacted vaccine hesitancy trends, potentially affecting parents' intentions to adhere to scheduled childhood vaccination programs. Aim This article aims to assess the extent of parents' hesitancy toward childhood vaccination, determine if it increased or decreased due to the COVID-19 pandemic, highlight the factors and determinants that influenced this hesitancy, whether positively or negatively, during the COVID-19 era, and estimate the acceptance of COVID-19 vaccination in relation to the acceptance of scheduled childhood vaccination. Methods A cross-sectional study was conducted in Saudi Arabia through a snowball sampling technique. Data were collected between September 2022 and October 2022 using an online survey using Google Forms. The inclusion criteria were parents or guardians in Saudi Arabia with a child up to 18 years of age. Responses were analyzed using SPSS V25 (IBM Corp., Armonk, NY, US), with chi-square tests and logistic regression performed to compare hesitancy and vaccination status. Results Among the 1,209 parents and care providers who participated, the prevalence of parents' vaccine hesitancy was 374 (30.9%). The educational level of the parents was not significantly associated with hesitancy status (p 0.490). The most refused vaccine was Mpox (345; 28.5%), whereas the one that caused the most hesitancy was the COVID-19 vaccine (352; 29.1%). Regarding the parents' concerns, the main reason for their hesitancy was the influence of their negative perceptions from social media content, including false or misleading information and negative allegations about vaccines, reported by 449 (18.98%) of the participants. Logistic regression analysis indicated that negative social media perceptions significantly increased the likelihood of vaccine hesitancy (OR = 2.15, 95% CI = 1.78-2.60, p < 0.001). Conclusion Our study highlights the prevalence of parental vaccine hesitancy during the COVID-19 era; the most significant hesitancy was observed toward the COVID-19 vaccine, and the mpox vaccine was the most rejected. Negative social media was the main reason for parental hesitancy; public health efforts should focus on providing accurate and easily accessible information through educational campaigns on social media and other platforms.

RESUMO

BACKGROUND: Children born to adolescent mothers are more vulnerable to infant mortality and morbidity than those born to adult mothers. HIV-exposed children have lower antibody protection against vaccine-preventable diseases at birth compared to unexposed children. In South Africa, 17 % of adolescent girls aged 15-19 years are mothers, yet vaccination coverage and timeliness among their children is underreported. METHODS: This study estimated age-appropriate vaccination coverage and timeliness among children (n = 1080) of adolescent mothers (n = 1015) in the Eastern Cape, South Africa. Mother-child dyads were recruited through healthcare and community-based sampling strategies. Vaccination data were abstracted from 1013 home-based child health records (2017-2019). Coverage is reported for Diphtheria-Tetanus-Pertussis 3rd dose (DTP3), under-1 vaccination among children over 12 months (n = 613) and measles 2nd dose (MCV2) among children over 24 months (n = 382) using proportions with 95 % confidence intervals (95 %CI). Timeliness is defined as receiving each vaccination within 4 weeks of recommended age. Findings are disaggregated by maternal HIV-status. RESULTS: Overall, 27.3 % of adolescent mothers were living with HIV. Coverage of DTP3 was 85.6 % (95 %CI: 82.6-88.3 %), under-1 coverage was 53.2 % (95 %CI: 49.1-57.2 %), and MCV2 coverage was 62.3 % (95 %CI: 57.2-67.2 %). Vaccination coverage was lower among children of adolescent mothers living with HIV (AMLHIV) than unexposed children (DTP3 80.3 % vs 88.2 % p-value: 0.01; under-1 46.5 % vs 56.4 % p-value: 0.02; MCV2 55.4 % vs 67.1 % p-value: 0.02). Timeliness of vaccinations declined over time from 98.0 % at birth, 70.7 % at 14 weeks, 71.9 % at 9 months and 37.3 % at 18 months. CONCLUSION: Vaccination coverage among children of adolescent mothers in the Eastern Cape are below national targets. Children of AMLHIV had lower coverage than HIV-unexposed children. Further research is needed to identify risk factors associated with incomplete and delayed vaccinations among this group, particularly among HIV-exposed children. Enhanced vaccination campaigns may be required for children of adolescent mothers.

RESUMO

The second dose of measles-containing vaccines (MCV2) has significant programmatic relevance in the current immunisation landscape because it serves as both an opportunity to reduce measles immunity gaps and strengthen second year of life vaccination platforms. However, MCV2 coverage remains suboptimal across countries in the World Health Organization (WHO) African Region and this puts a significant number of children at risk of morbidity and mortality from measles despite the availability of an effective vaccine. There is an urgent need to strengthen the implementation of MCV2 but this requires a thorough and systematic understanding of contextual factors that influence it. The literature that describes the determinants of implementation of MCV2 in a manner that adequately accounts for the complexity of the implementation context is scarce. Therefore, the purpose of this rapid review was to explore the implementation determinants of MCV2 in the WHO African Region using systems thinking. Literature search in two databases (PubMed and Google Scholar) were conducted. After screening, a total of 17 eligible articles were included in the study. Thematic analysis of extracted data was performed to identify the implementation determinants, after which they were mapped using the Consolidated Framework for Implementation Research (CFIR). A causal loop diagram (CLD) was used to illustrate the linkages between identified determinants. We found 44 implementation determinants across the five CFIR domains, i.e., innovation, outer setting, inner setting, individual, and implementation process. The majority of identified determinants are within the individual domain followed by the inner setting domain. The CLD showed that multiple contingent connections and feedback relationships exist between the identified implementation determinants within and across CFIR domains. The linkages between the implementation determinants revealed three balancing and reinforcing loops each. The findings suggest that implementation determinants of second-dose measles vaccination in the WHO African Region are complex, with multiple interconnections and interdependencies, and this insight should guide subsequent policies. There is an urgent need for further implementation research with embedded CLD in specific settings to inform the design of tailored systemic strategies to improve the implementation effectiveness of MCV2.

RESUMO

BACKGROUND: Cameroon, a country in sub-Saharan Africa, ranks among the top 15 countries worldwide with the highest number of zero-dose (unvaccinated) children. Among other reasons, pockets of hard-to-reach communities that traditionally miss essential healthcare services, including childhood immunization, largely contribute to this sub-optimal vaccination coverage. This is the case of Manoka Health District (MHD), an archipelago district with a zero-dose proportion of 91.7%. High disease burdens such as malaria and water-borne diseases have forced the population to depend on herbalists and roadside drug vendors, eroding trust in the primary healthcare system and worsening vaccine hesitancy. This study, therefore, aims to describe how a project optimized vaccine demand generation in these hard-to-reach settlements using an integrated community health worker service delivery package developed using the Community-oriented primary healthcare (COPC) model. METHODOLOGY: This cross-sectional descriptive study was based on data collected from November 2021 to August 2022 in three project-implementing health areas (Kombo Moukoko, Kooh, and Toube) in the Manoka health district. Data was collected on the integrated health packages offered by Community Health Workers (CHWs). It comprised health education on malaria and water-borne diseases, screening for malaria using Rapid Diagnostic Test (RDT), treatment of under-5 for uncomplicated malaria and diarrhea, conduct of essential Antenatal Care (ANC) services, and vaccination counseling and referral in the three health areas. Microsoft Excel 2013 was used to analyze descriptive data and expressed results as percentages, with tables and column charts used for data visualization. All missing data were considered in the final analysis. RESULTS: Over 550 under-5 children and 187 pregnant women were identified to be in need of curative and preventive care services during the project period. About 81% of pregnant women received a minimum ANC package by CHWs, and 47% adhered to referrals to health facilities for continuous ANC and delivery. Half of the children under 5 with health issues were diagnosed and managed for uncomplicated malaria. Also, during home visits, 617 under-immunized and zero-dose children less than two years of age were identified, referred, and vaccinated either during an outreach program or at the nearest health post in a neighboring health area, representing about 64% (617/964) of under-2 children identified in these communities. There was a gradual increase from 0% vaccine acceptance post-referral in the first month to 47% after six months and 64% at one year of intervention. CONCLUSION: The use of the COPC model to co-develop integrated essential health service packages that meet the needs of communities showed value in building trust and increasing childhood immunization uptake in hard-to-reach communities.

RESUMO

Despite overall improvements observed at the national level, there is a significant disparity in childhood vaccination coverage rates between urban and rural regions, particularly within tribal and remote areas in Pakistan. Our study aimed to explore the views of community/tribal leaders concerning barriers and their local solutions for improving vaccine uptake, with a specific focus on remote settings. An exploratory qualitative research study was conducted from July to September 2019 in Shikarpur, Sindh, Pakistan. We interviewed 11 community leaders, after developing a semi-structured interview guide based on the health belief model. Following validation, the collected data was transcribed and subsequently translated into the English language. A stepwise process of manual familiarization, coding, theme generation, and theme review using an inductive approach was followed. While most of the rural community leaders expressed a willingness to support vaccinations, numerous unexplored barriers were identified. These barriers included an unsustainable communication system heavily dependent on polio mobile teams, discourteous behavior of healthcare personnel, cultural restrictions that limited women's involvement, economic hardships, limited transportation options, insufficient collaboration with the education sector, poor knowledge among community leaders, and security concerns. Additionally, they proposed some innovative solutions of information dissemination methods through the Ottaque system, ethics-based training, subsidized transportation services or voucher system, and addressing security concerns in collaboration with community leaders. Our findings suggest policymakers take both community leaders and members for an inclusive policy-making process to redraft the special policy for these remote and rural areas.

RESUMO

An increasing vaccine hesitancy among parents, which has resulted in insufficient rates of immunization, provides reason to reconsider childhood vaccination practices. Studies suggest that parents' decision-making process concerning whether to vaccinate their child is highly influenced by cognitive biases. These biases can be utilized to increase vaccination uptake via changes in the choice context. This article considers childhood vaccination programmes, which involve children being vaccinated in school or daycare unless their parents actively 'opt out'. We suggest that such programmes reconcile parents' decisional authority and vaccination duties. First, opt-out childhood vaccination based in schools or daycare centres are not disrespectful of parental authority. Second, the programme aligns the default setting with a moral obligation to vaccinate one's child that most parents have.

RESUMO

BACKGROUND: Confidence in childhood vaccination is high in Norway and the Norwegian Childhood Immunization Programme (NCIP) achieves high overall coverage rates. However, lower coverage has been observed for some immigrant groups, including Polish immigrants who represent the largest immigrant group in Norway. Anti-vaccine sentiments and increased refusal of mandatory childhood vaccination has been on the rise in Poland, but it is unknown whether such attitudes also apply to Polish immigrants in Norway, as they experience a different vaccination policy and perhaps also different attitudes to vaccines. This qualitative study aims to explore attitudes towards childhood vaccination in Norway among Polish immigrants. METHODS: We interviewed 15 Polish parents living in Norway in 2022. We recruited the participants by purposive sampling and analyzed the interviews by reflexive thematic analysis. RESULTS: Three themes were identified: views of childhood vaccination, vaccine hesitancy, and differences in childhood vaccination between Poland and Norway. Overall, the participants favored childhood vaccination and viewed most of the vaccines included in the NCIP as safe and reliable. Human papilloma virus, meningococcal and pneumococcal vaccines were declined by some of the parents. Comparisons of childhood vaccination in Poland and Norway was evident in many of the interviews, especially among parents whose children had received vaccines in both countries. The participants were well acquainted with the NCIP, favored voluntary childhood vaccination, and the majority expressed a high level of trust in Norwegian health authorities. CONCLUSIONS: Polish immigrants to Norway generally expressed positive views about childhood vaccination. Non-vaccination was related to lack of knowledge and/or unfamiliarity with certain vaccines and not with anti-vaccine sentiments or conspiracy theories. The study highlights how parents' knowledge, in combination with norms and trends from both birth country and country of residence, influence parents' decision making about vaccination.

RESUMO

BACKGROUND: The aim of this review was to investigate the impact of short message service (SMS)-based interventions on childhood and adolescent vaccine coverage and timeliness. METHODS: A pre-defined search strategy was used to identify all relevant publications up until July 2022 from electronic databases. Reports of randomised trials written in English and involving children and adolescents less than 18 years old were included. The review was conducted in accordance with PRISMA guidelines. RESULTS: Thirty randomised trials were identified. Most trials were conducted in high-income countries. There was marked heterogeneity between studies. SMS-based interventions were associated with small to moderate improvements in vaccine coverage and timeliness compared to no SMS reminder. Reminders with embedded education or which were combined with monetary incentives performed better than simple reminders in some settings. CONCLUSION: Some SMS-based interventions appear effective for improving child vaccine coverage and timeliness in some settings. Future studies should focus on identifying which features of SMS-based strategies, including the message content and timing, are determinants of effectiveness.

RESUMO

Background: The United States Food and Drug Administration authorized COVID-19 vaccines for children ages 5-11 years in October 2021 during the Omicron predominant period. Parental vaccine hesitancy was prevalent during this time, resulting in low childhood COVID-19 vaccine uptake. Most studies exploring factors influencing parental vaccine hesitancy have focused on racial and ethnic minorities and lower socioeconomic populations; however, there is little knowledge of the drive drivers of vaccine hesitancy among White parents with higher education and socioeconomic statuses. Methods: We conducted semi-structured interviews with a sample of 15 White mothers of children ages 5-11 years in Atlanta, GA, between October-December 2021. Thematic analysis was performed using NVivo 12. Results: Mothers were college-educated, homeowners, and fully vaccinated against COVID-19. Key findings included decreased pediatrician's recommendations for COVID-19 vaccines, reliance on information from specialized doctors and scientists, distrust in public health authorities, high risk-perception of COVID-19 vaccines, and low risk-perception of COVID-19 disease. Factors related to vaccine acceptance were altruism and practicality. Conclusion: This study adds to the sparse literature on reasons for vaccine hesitancy among White mothers of children ages 5-11 years with higher educational and socioeconomic status. Improving vaccine uptake among this group is critical for protecting the health of their children and other vulnerable populations. Tailored vaccine messaging and intervention are warranted to address their unique attitudes, beliefs, and behaviors. An enhanced understanding of the factors influencing subpopulations of parents can help vaccine policymakers and healthcare providers improve efforts to reduce vaccine hesitancy, particularly for new vaccines.

RESUMO

This systematic review and meta-analysis aimed to examine the association between maternal education and completion of childhood vaccination among aged 12-23 months children in Ethiopia. Systematic review and meta-analysis. PubMed-Medline, EMBASE, SCOPUS, Global Health, and Google Scholar were searched for articles published from January 2010 to January 2020. The data extraction was reported based on the PRISMA guideline (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. We performed the I2 test and a funnel plot to assess heterogeneity and check for publication bias. We assessed 841 studies for eligibility, of which 43 studies were included in the qualitative synthesis, and 28 studies were fully accessed for meta-analysis. The overall pooled effect of this systematic review and meta-analysis demonstrated a positive association between maternal education and completion of childhood vaccination. Having a primary level of maternal education was correlated with a 1.87 times higher likelihood (95% CI 1.76-1.98) of completing childhood vaccination compared to having no education. Furthermore, attending secondary education and above was associated with a 3.47 times higher likelihood (95% CI 3.18-3.78) of completing childhood vaccination compared to having no education. This systematic review and meta-analysis study revealed that as the level of maternal education increases, the completion of childhood vaccination accelerates. Therefore, investment in maternal education should be prioritized as an intervention. Empowering mothers through education can contribute to the reduction and prevention of vaccine-preventable diseases and associated risks.

RESUMO

Data on routine childhood vaccination coverage can only tell us who is under-vaccinated; it cannot explain why vaccine coverage is low. Collecting data on the reasons behind under-vaccination is necessary to implement cost-effective strategies that address key barriers and target interventions appropriately. However, no instruments that measure both vaccine acceptance and access factors among parents of children <5 y have been validated in high-income countries. This study aims to develop and validate the Vaccine Barriers Assessment Tool (VBAT) for Australia. We applied three phases of mixed methods data collection and analysis. In Phase 1, we developed a comprehensive list of 80 items reflecting all potential parental barriers to childhood vaccination, derived from published literature and behavioral theory. Through cognitive interviews (n = 28), we refined this list to 45 items. In Phase 2, we conducted a two-wave online survey to test the reliability and validity of these items in an Australian sample of parents (n = 532) with structural equation modeling, further refining the list to 35 items. In Phase 3, we conducted a final parent survey (n = 156), administering these items along with the Parent Attitudes toward Childhood Vaccination (PACV) scale for comparison. We reviewed participants' immunization register data to assess the predictive validity of the proposed models. The final 6-item short form and 15-item long form Vaccine Barriers Assessment Tool assess access, communal benefit, personal risk, equity, commitment, social norms, and trust in health-care workers. It is being applied for national surveillance in Australia and will be adapted for additional populations and vaccines.

RESUMO

BACKGROUND: Mandates provide a relatively cost-effective strategy to increase vaccinate rates. Since 2014, five Australian states have implemented No Jab No Play (NJPlay) policies that require children to be fully immunised to attend early childhood education and childcare services. In Western Australia, where this study was conducted, NJNPlay legislation was enacted in 2019. While most Australian families support vaccine mandates, there are a range of complexities and unintended consequences for some families. This research explores the impact on families of the NJNPlay legislation in Western Australia (WA). METHODS: This mixed-methods study used an online parent/carer survey (n = 261) representing 427 children and in-depth interviews (n = 18) to investigate: (1) the influence of the NJNPlay legislation on decision to vaccinate; and (2) the financial and emotional impacts of NJNPlay legislation. Descriptive and bivariate tests were used to analyse the survey data and open-ended questions and interviews were analysed using reflexive thematic analysis to capture the experience and the reality of participants. RESULTS: Approximately 60% of parents intended to vaccinate their child. Parents who had decided not to vaccinate their child/ren were significantly more likely to experience financial [p < 0.001] and emotional impacts [p < 0.001], compared to those who chose to vaccinate because of the mandate. Qualitative data were divided with around half of participants supporting childhood immunisation and NJNPlay with others discussing concerns. The themes (a) belief in the importance of vaccination and ease of access, (b) individual and community protection, and (c) vaccine effectiveness, safety and alternatives help understand how parents' beliefs and access may influence vaccination uptake. Unintended impacts of NJNPlay included: (a) lack of choice, pressure and coercion to vaccinate; (b) policy and community level stigma and discrimination; (c) financial and career impacts; and (d) loss of education opportunities. CONCLUSIONS: Parents appreciation of funded immunisation programs and mandates which enhance individual and community protection was evident. However for others unintended consequences of the mandate resulted in significant social, emotional, financial and educational impacts. Long-term evidence highlights the positive impact of immunisation programs. Opinions of impacted families should be considered to alleviate mental health stressors.

RESUMO

IMPORTANCE: Routine vaccinations are key to prevent outbreaks of vaccine-preventable diseases. However, there have been documented declines in routine childhood vaccinations in the U.S. and worldwide during the COVID-19 pandemic. OBJECTIVE: Assess how the COVID-19 pandemic impacted routine childhood vaccinations by evaluating vaccination coverage for routine childhood vaccinations for children born in 2016-2021. METHODS: Data on routine childhood vaccinations reported to CDC by nine U.S. jurisdictions via the immunization information systems (IISs) by December 31, 2022, were available for analyses. Population size for each age group was obtained from the National Center for Health Statistics' Bridging Population Estimates. MAIN OUTCOMES AND MEASURES: Vaccination coverage for routine childhood vaccinations at age three months, five months, seven months, one year, and two years was calculated by vaccine type and overall, for 4:3:1:3:3:1:4 series (≥4 doses DTaP, ≥3 doses Polio, ≥1 dose MMR, ≥3 doses Hib, ≥3 doses Hepatitis B, ≥1 dose Varicella, and ≥ 4 doses pneumococcal conjugate), for each birth cohort year and by jurisdiction. RESULTS: Overall, there was a 10.4 percentage point decrease in the 4:3:1:3:3:1:4 series in those children born in 2020 compared to those children born in 2016. As of December 31, 2022, 71.0% and 71.3% of children born in 2016 and 2017, respectively, were up to date on their routine childhood vaccinations by two years of age compared to 69.1%, 64.7% and 60.6% for children born in 2018, 2019, and 2020, respectively. CONCLUSIONS AND RELEVANCE: The decline in vaccination coverage for routine childhood vaccines is concerning. In order to protect population health, strategic efforts are needed by health care providers, schools, parents, as well as state, local, and federal governments to work together to address these declines in vaccination coverage during the COVID-19 pandemic to prevent outbreaks of vaccine preventable diseases by maintaining high levels of population immunity.

RESUMO

BACKGROUND: The newly developed malaria vaccine called "R21/Matrix-M malaria vaccine" showed a high safety and efficacy level, and Ghana is the first country to approve this new vaccine. The present study aimed to evaluate the rate of vaccine hesitancy (VH) towards the newly developed malaria vaccine among parents who currently have children who are not eligible for the vaccine but may be eligible in the near future. Additionally, the study aimed to identify the factors that could potentially influence VH. METHODS: A cross-sectional survey using both online-based questionnaires and face-to-face interviews was conducted in Ghana from June to August 2023. The survey specifically targeted parents of ineligible children for vaccination, including those aged less than 5 months or between 3 and 12 years. The Parent Attitudes about Childhood Vaccination (PACV) scale was used to assess parental VH. RESULTS: A total of 765 people participated in this study. Their median age was 36.0 years with an interquartile range of 31.0-41.0 years, 67.7% were females, 41.8% completed their tertiary education, 63.3% were married, 81.6% worked in non-healthcare sectors, and 59.7% reported that their monthly income was insufficient. About one-third (34.5%) of the parents were hesitant to give their children the R21/Matrix-M malaria vaccine. The following predictors were associated with VH: working in the healthcare sector (adjusted odds ratio (AOR) = 0.50; 95% confidence interval (CI) 0.30-0.80; p = 0.005), having the other parent working in the healthcare sector (AOR = 0.54; 95% CI 0.30-0.94; p = 0.034), and not taking scheduled routine vaccinations (AOR = 1.90; 95% CI 1.27-2.84; p = 0.002). CONCLUSIONS: Addressing VH is crucial for optimizing R21/Matrix-M vaccine coverage in Ghana's malaria control strategy. By tackling VH issues, Ghana can effectively safeguard children's health in malaria-prone areas.

RESUMO

Introduction: Routine immunization programs have focused on increasing vaccination coverage, which is equally important for decreasing vaccine-preventable diseases (VPDs), particularly in low- and lower-middle-income countries (LMICs). We estimated the trends and projections of age-appropriate vaccination coverage at the regional and national levels, as well as place of residence and wealth index in LMICs. Methods: In total, 174 nationally representative household surveys from 2000 to 2020 from 41 LMICs were included in this study. Bayesian hierarchical regression models were used to estimate trends and projections of age-appropriate vaccination. Results: The trend in coverage of age-appropriate Bacillus Calmette-Guérin (BCG), third dose of diphtheria, tetanus, and pertussis (DTP3), third dose of polio (polio3), and measles-containing vaccine (MCV) increased rapidly from 2000 to 2020 in LMICs. Findings indicate substantial increases at the regional and national levels, and by area of residence and socioeconomic status between 2000 and 2030. The largest rise was observed in East Africa, followed by South and Southeast Asia. However, out of the 41 countries, only 10 countries are estimated to achieve 90% coverage of the BCG vaccine by 2030, five of DTP3, three of polio3, and none of MCV. Additionally, by 2030, wider pro-urban and -rich inequalities are expected in several African countries. Conclusion: Significant progress in age-appropriate vaccination coverage has been made in LMICs from 2000 to 2020. Despite this, projections show many countries will not meet the 2030 coverage goals, with persistent urban-rural and socioeconomic disparities. Therefore, LMICs must prioritize underperforming areas and reduce inequalities through stronger health systems and increased community engagement to ensure high coverage and equitable vaccine access.

RESUMO

BACKGROUND: Even though childhood vaccination is a common and cost-effective public health intervention in preventing and reducing childhood disease and death, significant numbers of children do not complete vaccination within the first year of life. Studies indicated that user satisfaction influences service utilization and used as a key indicator of quality care. However, evidence on the level of mothers' satisfaction with immunization service are limited in urban and accessible places and not well investigated among remote and pastoral communities. As such, this study aimed to address this gap and investigated mothers' satisfaction towards child vaccination in a pastoralist and agrarian community of the South Omo zone in Southern region of Ethiopia. METHODS: An institution-based cross-sectional study was conducted among 1221 randomly selected mothers with children eligible for childhood vaccination using a structured, pretested, and interviewer-administered questionnaire. Maternal positive evaluations of the overall vaccination service were measured using 5-point Likert scale questions. Data were entered into Epi data version 3.5.1 and analyzed using IBM SPSS statistical package version 25. Exploratory factor analysis was used for Likert scale questions to extract factor scores which facilitate treatment of variables as continuous for further analysis. Bivariate and multivariable logistic regression analysis was employed to identify factors associated with the outcome variable. A P-value < 0.05 and adjusted odds ratio with 95% CI respectively were used to declare statistical significance and degree of association. RESULT: A total of 849 (69.53%) study participants were satisfied with the vaccination care provided for their children. Factors associated with mother's satisfaction with child vaccination care include maternal age less than 30 years (AOR = 2.12; 95% CI = 1.61-2.79), infants age between 8 and 12 months (AOR = 1.83; 95% CI = 1.28, 2.62), not having history of adverse events following immunization (AOR = 1.57; 95% CI = 1.01-2.45), having 1 child under the age of 5 years (AOR = 1.34; 95% CI = 1.02-1.76), waiting 30 min or less to get the service (AOR = 1.39; 95% CI = 1.05-1.85), traveling 30 min or less to the vaccination center (AOR = 1.46; 95% CI = 1.08-1.98), having poor knowledge about the importance of vaccination (AOR = 1.51; 95% CI = 1.06-2.16), and having moderate knowledge about the importance of vaccination (AOR = 1.52; 95% CI = 1.06-2.18). CONCLUSION: Interestingly, mothers' satisfaction with their children's vaccination service was relatively higher in a predominantly pastoral community compared with most of previous studies conducted in Ethiopia. Maternal and child age, number of children under the age of 5 years, history of adverse events following immunization, distance to the vaccination center, waiting time to get service and maternal knowledge were factors significantly associated with mothers' satisfaction. Proactive measures with focus on increasing access to vaccination service, improving waiting time and raising awareness among mothers were recommended.

RESUMO

INTRODUCTION: Knowledge and trust are some of the contributing factors to vaccine acceptance(VA) and Vaccine hesitancy (VH) is one of the top threats to global health. A significant drop in childhood vaccination has been observed in recent years. One important reason that influences mothers' choice to either postpone or avoid children's vaccinations is knowledge and trust in childhood vaccines. This study aimed to assess mothers' knowledge and trust on vaccination of their children, and to examine the association between vaccination knowledge and selected socio-demographic factors. METHODS: A cross-sectional survey was conducted from January 2022 to March 2022 to assess the knowledge and trust of mothers regarding childhood vaccination. Data was collected with self-administered questionnaires. Multivariable logistic regression analysis was employed to assess factors associated with childhood vaccine knowledge and trust. RESULTS: Of the 2,126 Rwandan parents who participated in the study, the proportions with good knowledge of - and good trust in childhood vaccination were 95.5% and 91.4%, respectively. The popular sources of information about childhood vaccination were health care professionals (91.8%) and mass media (28.9%). Multinomial logistic regression analysis showed that good knowledge of - and trust in childhood vaccination were associated with the relationship with child(ren), education, occupation, and monthly income. The Multinomial logistic regression also revealed that the determinants of good knowledge of - and trust in childhood vaccination were; caregiver (p = 4.0 × 10-4, adjusted Odds Ratio (aOR); 1.7, 95%C.I; 1.3 - 2.3), no formal educational status (p = 3.3 × 10-2, aOR; 1.7, 95%C.I; 1.0 - 3.0), the unemployed occupational status (p = 2.4 × 10-2, aOR; 1.2, 95%C.I; 1.0 - 1.4), and persons on more than $401 per month (p = 2.0 × 10-4, aOR; 3.5, 95%C.I; 1.8 - 6.8). CONCLUSION: The majority of parents in Rwanda had both good knowledge of-and good trust regarding childhood vaccination. Public health strategies to promote vaccination, education programmes as well as improved communication tools between health care professionals/traditional leaders/religious leaders and parents need to be considered to achieve favourable vaccination attitudes and practices for all parents in Rwanda.

RESUMO

BACKGROUND: The Norwegian Childhood Immunization Program maintains a high national coverage of 95-97% in the most recent years. Whether there are subgroups with lower uptake is less studied. This study examines pertussis and measles vaccination coverage among six immigrant groups in Norway. These vaccines are normally administered as part of different combination vaccines and their coverage rate indicate the national vaccination coverage against a range of additional infections. METHODS: Data from the Norwegian National Population Register were linked at individual level with vaccination data from the Norwegian Immunisation Registry. The final sample consisted of 53,052 children born during 2000-2018 in Norway to parents who were born in Iraq, Lithuania, Pakistan, Poland, Somalia, or Vietnam. Vaccination coverage was measured at 2-years of age. Multivariate linear regression was utilized to estimate the relationship between vaccinations status, year of birth, gender, mother's length of residency in Norway, and area of residence. RESULTS: At two years of age, the majority of the children were vaccinated. Coverage among the groups varied at, above, and below the national average for the two vaccines. For most of the years examined, children born by parents from Lithuania, Poland, and Somalia had lower coverage for the measles vaccine (range 81-84% in 2020) than the national level (97% in 2020). Children born by parents from the Eastern-European countries also had lower coverage than the national level for the pertussis vaccine (range 87-89% in 2020). DISCUSSION: This study illustrates how subgroups with lower vaccination coverage may exists within a well-established vaccination program with high national coverages. Differences in coverage were found for both vaccines, but the differences were more pronounced for the measles vaccine. The high vaccination coverage in Norway provides indirect protection through herd immunity for unvaccinated individuals, however, the lower vaccination coverage in some immigrant groups is a concern.
