Nurses' attitudes towards COVID-19 vaccines: A qualitative study (PROACTIVE-study).

AIM: To explore the attitudes of healthcare workers towards COVID-19 vaccines. DESIGN: A qualitative descriptive design was used. METHODS: Five focus groups were conducted between October and November 2021, with a total of 30 nurses from different contexts in Northern Italy. Thematic analysis was used to analyse the transcripts. RESULTS: Three main themes were identified: 'favourable', 'unsure' and 'contrary to' COVID-19 vaccines. The favourable position was underpinned by trust in science, research and vaccination; protection for themselves, their families, patients and the population; duty as professionals; necessity to set an example for others. Participants who were unsure had doubts about the composition, safety and efficacy of the vaccine and were sometimes afraid that media provided incomplete information. The main reason why nurses were against was the feeling that being forced to vaccinate perceived as blackmail. Favourable or unsure nurses struggled to deal with those who were against and developed a series of emotions that ranged from respect and attempt to rationalize, to frustration and defeat. CONCLUSIONS: Identifying the areas of hesitation is essential to understand what affects the choices of acceptance, delay or refusal of vaccination. The issues that emerged regarding proper communication within the vaccination campaign highlights the key importance of adequate vaccination strategies. IMPLICATION FOR THE PROFESSION AND/OR PATIENT CARE: Understanding attitudes towards vaccine and related motivations among healthcare workers could help develop more specific and targeted vaccination campaigns that can ensure proper vaccination coverage rates and avoid hesitancy or refusal. IMPACT: Healthcare workers experiences of COVID-19 vaccines, their views and know how they feel during COVID-19 vaccinations. Healthcare workers had three different positions in COVID-19 vaccination. This research will guide and target future vaccination campaigns. REPORTING METHOD: The study is reported using the Standards for Reporting Qualitative Research (SRQR). PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

The Relationship Between Household Microfinance Group Participation and Vaccine Adherence Among Children in Rural Western Kenya.

INTRODUCTION: High childhood vaccine adherence is critical for disease prevention, and poverty is a key barrier to vaccine uptake. Interventions like microfinance programs that aim to lift individuals out of poverty could thus improve vaccine adherence of the children in the household. BIGPIC Family Program in rural Western Kenya provides group-based microfinance services while working to improve access to healthcare and health screenings for the local community. The aim of the present paper is to evaluate the association between household participation in BIGPIC's microfinance program and vaccine adherence among children in the household. We hypothesize that microfinance group participation will have a positive impact on vaccine adherence among children in the household. METHODS: From 2018 to 2019, we surveyed a sample of 300 participants from two rural communities in Western Kenya, some of whom were participants in the BIGPIC Family's microfinance program. The primary outcome of interest was vaccine adherence of children in the household. Log-binomial models were used to estimate the relationship between microfinance group participation and vaccine adherence, adjusted for key covariates. We also assessed whether the relationship differed by gender of the adult respondent. RESULTS: Microfinance group members were more likely to have all children in their households fully vaccinated [aPR (95% CI): 1.68 (1.20,2.35)] compared to non-microfinance group members. Further, the association was stronger when women were the microfinance members [PR (95% CI): 1.87 (1.27,2.76)] compared to men [PR (95% CI): 1.24 (0.81,1.90)]. CONCLUSIONS: Microfinance participation was associated with higher childhood vaccine adherence in rural Western Kenya. Microfinance interventions should be further explored as strategies to improve child health and well-being in low- and middle-income countries.

Influences on COVID-19 Vaccine Adherence among Pregnant Women: The Role of Internet Access and Pre-Vaccination Emotions.

INTRODUCTION: The onset of the COVID-19 pandemic brought about global uncertainties and fears, escalating the dissemination of fake news. This study aims to analyze the impact of fake news on COVID-19 vaccine adherence among pregnant women, providing crucial insights for effective communication strategies during the pandemic. METHODS: A cross-sectional, exploratory study was conducted with 113 pregnant women under care at a Women's Health Reference Center. Data analysis included relative frequency and odds ratio to assess the relationship between sociodemographic and behavioral variables regarding vaccination. RESULTS: In the behavioral context of vaccination, internet access shows a significant association with decision-making, influencing vaccine refusal due to online information. Nuances in the odds ratios results highlight the complexity of vaccine hesitancy, emphasizing the importance of information quality. Pre-vaccination sentiments include stress (87.61%), fear (50.44%), and anxiety (40.7%), indicating the need for sensitive communication strategies. DISCUSSION: Results revealed that pregnant women with higher education tend to adhere more to vaccination. Exposure to news about vaccine inefficacy had a subtle association with hesitancy, while finding secure sources was negatively associated with hesitancy. The behavioral complexity in the relationship between online information access and vaccination decision underscores the need for effective communication strategies. CONCLUSIONS: In the face of this challenging scenario, proactive strategies, such as developing specific campaigns for pregnant women, are essential. These should provide clear information, debunk myths, and address doubts. A user-centered approach, understanding their needs, is crucial. Furthermore, ensuring information quality and promoting secure sources are fundamental measures to strengthen trust in vaccination and enhance long-term public health.

Vaccination Trends and Family-Level Characteristics Associated With Incomplete or Delayed Childhood Immunizations: The Healthy Start Study.

PURPOSE: Assess family-level factors associated with childhood immunization schedule adherence. DESIGN: Prospective cohort; Setting; The Healthy Start study enrolled 1,410 pregnant women in Denver, Colorado 2009-2014. SUBJECTS: Children with available vaccination data in medical records (0-6 years old). MEASURES: Vaccine schedule completion and compliance. ANALYSIS: Logistic regression comparing family-level factors that differ based on vaccine schedule adherence. RESULTS: Most immunizations required in Colorado for school entry were below national completion goals with 61.8% of participants (n = 532/861) completing the full vaccination series. Most participants received the first dose of individual vaccines on time (73.5% - 90.7%), but fewer received all doses on time (21.0% - 39.5%). Factors associated with not completing the vaccination series (OR [95% CI]) included: in-utero exposure to cigarette smoke (1.97 [1.41, 2.75]), single parent household (1.70 [1.21, 2.38]), children identified as non-White (Hispanic 1.40 [1.01, 1.94]; Black 1.88 [1.24, 2.85]; Other 2.17 [1.34, 3.49]), mothers not working outside the home (1.98 [1.46, 2.67]), and household income <$70,000 per year (<$40,000 1.93 [1.35, 2.75]; $40,000-$70,000 1.64 [1.09, 2.46]). Conversely, families with more educated mothers (0.47 [0.29, 0.76]) and older parents (0.97 [0.94, 0.99]) were significantly more likely to complete the series. CONCLUSIONS: These findings may help identify groups at risk of immunization schedule non-adherence and may be used to target education/advocacy campaigns to reduce hesitancy and increase access in these populations.

Adherence to Vaccines in Adult Patients with Immune-Mediated Inflammatory Diseases: A Two-Year Prospective Portuguese Cohort Study.

BACKGROUND: Patients with immune-mediated inflammatory diseases (IMIDs) treated with immunomodulatory therapy present an increased susceptibility to infections. Vaccination is a crucial element in the management of IMID patients; however, rates remain suboptimal. This study intended to clarify the adherence to prescribed vaccines. MATERIALS AND METHODS: This prospective cohort study included 262 consecutive adults with inflammatory bowel disease and rheumatological diseases who underwent an infectious diseases evaluation before initiating or switching immunosuppressive/biological therapy. Vaccine prescription and adherence were assessed during an infectious diseases (ID) consultation using a real-world multidisciplinary clinical project. RESULTS: At baseline, less than 5% had all their vaccines up-to-date. More than 650 vaccines were prescribed to 250 (95.4%) patients. The most prescribed were pneumococcal and influenza vaccines, followed by hepatitis A and B vaccines. Adherence to each of the vaccines ranged from 69.1-87.3%. Complete adherence to vaccines occurred in 151 (60.4%) patients, while 190 (76%) got at least two-thirds of them. Twenty patients (8%) did not adhere to any of the vaccines. No significant differences were found in the adherence rates of patients with different sociodemographic and health-related determinants. CONCLUSIONS: ID physicians can play a role in the process of increasing vaccine prescription and adherence. However, more data on patients' beliefs and vaccine hesitancy, along with mobilization of all health care professionals and adequate local interventions, shall be considered to improve vaccine adherence.

Italian health professionals on the mandatory COVID-19 vaccine: An online cross-sectional survey.

Italy was the first country in Europe to make vaccination against COVID-19 mandatory for healthcare professionals by imposing restrictions in cases of non-compliance. This study investigates the opinions of the Italian healthcare professionals' categories affected by the regulation. We performed a qualitative online survey: the questionnaire comprised both close- and open-ended questions. The final dataset included n = 4,677 valid responses. Responses to closed-ended questions were analyzed with descriptive statistics. The framework method was applied for analyzing the open-ended questions. The sample spanned all health professions subject to compulsory vaccination, with a prevalence of physicians (43.8%) and nurses (26.3%). The vaccine adhesion before the introduction of the obligation was substantial. 10.4% declared not to have adhered to the vaccination proposal. Thirty-five percent of HPs who opted not to get vaccinated said they experienced consequences related to their choice. The trust in the vaccine seems slightly cracked, demonstrating overall vaccine confidence among professionals. Nonetheless, our results show that whether (or not) professionals adhere to vaccination is not a reliable indicator of consent to how it was achieved. There are criticisms about the lawfulness of the obligation. The data show a great variety of participants interpreting their roles concerning public and individual ethics. The scientific evidence motivates ethics-related decisions-the epidemic of confusing and incorrect information affected professionals. The Law triggered an increased disaffection with the health system and conflicts between professionals. Dealing with the working climate should be a commitment to assume soon.

COVID-19 Vaccination Knowledge, Perception, and Reason for Adherence and nonadherence Among Nursing Students in Egypt.

Introduction: Vaccines are considered preventive measures to reduce coronavirus disease 2019 (COVID-19) spread around the world. There are many factors for adherence and acceptance of COVID-19 vaccination. Objectives: The study aimed to investigate nursing students' knowledge, perception, and factors that influence their adherence to COVID-19 vaccines. Methods: A descriptive cross-sectional study design was conducted among nursing students at the Faculty of Nursing, Mansoura University, Egypt, during the period between September 1 and November 30, 2021. Results: Of the total of 500 participants, 76% took a COVID-19 vaccination. About 89% of participants rated the correct answer related to COVID-19 vaccination. Obligatory to enter the faculty, protect family and friends, and protect myself were the most reasons of adherence (80.3, 73.7, and 70.8%, respectively) while fear of adverse events and lack of information about vaccine were the most reasons of nonadherence (87.5 and 79.2%, respectively) to COVID-19 vaccination. The majority of participants (62%) had expressed positive perception toward COVID-19 vaccination. Education level, training program about COVID-19, previous infection with COVID-19, perception toward COVID-19 vaccination, and knowledge toward COVID-19 vaccination were significantly (p = .035, p = .027, p = .009, p = .008 and p = .033, respectively) associated with students' adherence to take COVID-19 vaccines. Conclusion: Accurate knowledge and perception about COVID-19 vaccines are the stronger predictors of vaccine hesitance or acceptance among nursing students in Egypt. Campaigns to increase knowledge and perception of COVID-19 and its vaccines among nursing students are needed to improve vaccine acceptance and reduce vaccine hesitance.

Global Implications for COVID-19 Vaccine Series Completion: Insights from Real-World Data from the United States.

This retrospective cohort analysis leveraged vaccination data for BNT162b2, mRNA-1273, and Ad26.COV2.S in the United States from the Komodo Healthcare Map database, the TriNetX Dataworks USA Network, and Cerner Real-World EHR (electronic health record) Data to evaluate rates of adherence to and completion of COVID-19 vaccination series (November 2020 through June 2021). Individuals were indexed on the date they received the first dose of a COVID-19 vaccine, with an adherence follow-up window of 42 days. Adherence/completion rates were calculated in the overall cohort of each database and by month of initiation and stratified by age, race/ethnicity, and urban/rural status. Overall adherence and completion to 2-dose COVID-19 mRNA vaccine schedules ranged from 79.4% to 87.4% and 81.0% to 89.2%, respectively. In TriNetX and Cerner, mRNA-1273 recipients were generally less adherent compared with BNT162b2 across sociodemographic groups. In Komodo, rates of adherence/completion between mRNA-1273 and BNT162b2 were similar. Adherence/completion were generally lower in younger (<65 years) versus older recipients (≥65 years), particularly for mRNA-1273. No other sociodemographic-based gaps in vaccine adherence/completion were identified. These data demonstrate high but incomplete adherence to/completion of multidose COVID-19 vaccines during initial vaccine rollout in the United States. Multidose schedules may contribute to challenges associated with successful global vaccination.

Descriptive analysis of routine childhood immunisation timeliness in the Western Cape, South Africa.

Adherence to recommended age-specific immunisation schedules is critical in ensuring vaccine effectiveness against vaccine preventable diseases (VPDs). There is limited data on immunisation timeliness in sub-Saharan Africa. Therefore, this study assessed the timeliness of age-specific routine childhood immunisation within the Western Cape Province of South Africa. Participant records (N = 709) from a prospective health-facility based study conducted in Cape Town, SA in 2012-2016 were analysed. The outcome measure was receiving age-specific immunisations ≥4 weeks of that recommended for age as per the South African Expanded Programme on Immunisation (EPI-SA) schedule. Proportions, medians, inter-quartile ranges (IQR) and regression were used to obtain the prevalence, time-at-risk, and risk factors for delayed immunisation. A total of 652 /709 (91.9%) participants were eligible. Immunisation coverage declined with age from 94.9% (95% CI 92.9-96.4) at birth to 72.0% (95% CI 65.7-77.6) at 18 months. The highest delay in the uptake of vaccine doses was observed among the 3 rd dose of the DTP vaccine [163 (34.6% (95% CI 30.3-39.1)], while the lowest was seen among BCG [40 (6.5% (95% CI 4.7-8.8)]. The longest median time-at-risk of VPDs was among the 2 nd dose of the measles vaccine [12.9 (IQR 6.7-38.6) weeks] and the lowest was OPV birth dose [IQR 6.3 (5.3-9.1) weeks]. Low and upper-middle socio-economic quartiles were associated with delayed uptake of vaccine doses. Delayed vaccination increases the time of susceptibility to VPDs during infancy and childhood. There is a need to develop strategies aimed at mitigating factors associated with delay in uptake of routine childhood vaccines in the Western Cape. Mitigation strategies should provide vaccine education and mobile reminder systems. Education about timely vaccine uptake will aid in the provision of informed council from healthcare providers to caregivers. Multiple reminder systems could cater for low network coverage areas and caregivers with busy schedules.

Real-world evidence on adherence and completion of the two-dose recombinant zoster vaccine and associated factors in U.S. adults, 2017-2021.

INTRODUCTION: Poor compliance with adult vaccination recommendations contributes to substantial disease burden. Evidence on adherence, completion, and completion timeliness for the 2-dose recombinant herpes zoster vaccine (RZV) and factors associated with these outcomes is limited and not readily generalizable for the entire U.S. METHODS: This retrospective, observational study examined adherence, completion, and the impact of sociodemographic, clinical and geographical factors among U.S. adults ≥ 50 years receiving RZV (4/20/2017 to 3/31/2021), using a large, geographically representative administrative claims database. Continuous enrollment in a medical benefit plan for six months prior to and following the index date (first observed vaccine dose) was required. Adherence was defined as receipt of the 2nd dose within 2-6 months, per label recommendation. Completion (receipt of all doses) was assessed at 6, 12, 18, and 24 months. RESULTS: Among 726,352 adults included, the adherence rate was 71.8%. Among 208,311 adults with 24-month follow-up, the completion rate was 72.3% after 6 months and 86.2% after 24 months. Logistic regression showed low adherence/completion was associated with younger age, Black or Hispanic race/ethnicity, lower income, lower educational attainment, and possessing commercial rather than Medicare healthcare insurance. Recipients identified using pharmacy claims had much higher adherence (74.0%) than those identified using medical claims (48.0%). CONCLUSIONS: Adherence and completion rates for RZV are suboptimal, especially for adults aged 50-64, racial/ethnic minorities, individuals with lower socio-economic status and those without Medicare insurance. More research and public health efforts are needed to understand and address potential barriers to RZV uptake, adherence and completion.

COVID-19 and Influenza Vaccination Campaign in a Research and University Hospital in Milan, Italy.

BACKGROUND: Healthcare workers (HCWs) are a historical key target of influenza vaccination programs. For the 2021-2022 season, WHO considered the coadministration of a flu and a COVID-19 vaccine as acceptable and recommended it to allow for higher uptake of both vaccines. The aim of this study was to investigate demographic and occupational features of vaccinated HCWs, reasons behind flu vaccine acceptance and a possible effect of the coadministration of a COVID-19 vaccine, in order to potentially draw general conclusions on HCWs' attitude towards flu vaccination and inform further strategies for consistent improvement of vaccine acceptance. METHODS: a promotional and educational campaign, a gaming strategy, and vaccination delivery through both a large central hub and on-site ambulatories, were the implemented strategies. In the central hub, the flu/COVID-19 vaccine coadministration was offered. Statistical descriptive analysis, multiple correspondence analysis (MCA) and logistic regression models were performed. RESULTS: 2381 HCWs received the flu vaccine, prompting a vaccination coverage rate (VCR) of 52.0% versus 43.1% in the 2020-2021 campaign. Furthermore, 50.6% vaccinated HCWs belonged to the 18-39 years-old age group. The most expressed reasons for vaccine uptake were "Vaccination is the most effective strategy of prevention" (n = 1928, 81.0%), "As HCW it's my duty to get vaccinated to protect my patients" (n = 766, 32.2%), and the group of COVID-19-related reasons (n = 586, 24.6%). In addition, 23.3% HCWs received the flu vaccine in the current campaign but not in the previous one (newly vaccinated) and the flu/COVID-19 vaccine coadministration was more frequent in this group. A total of 51.0% HCWs were hesitant towards the coadministration, while residents and nurses showed the highest propensity to receive it. CONCLUSIONS: in the second year of the COVID-19 pandemic, the Fondazione's influenza VCR continued to increase, with the greatest participation among HCWs aged 18-39 years. A potential propelling role of the COVID-19 vaccine coadministration was highlighted.

Vaccination in the Philippines: experiences from history and lessons for the future.

In anticipation of a potential vaccine for COVID-19, vaccine uptake may be critical in overcoming the pandemic, especially in countries like the Philippines, which has among the highest rates of infection in the region. Looking at the progress of vaccination in the country - its promises, pitfalls, and challenges - may provide insight for public health professionals and the public. The history of vaccination in the Philippines is marked by strong achievements, such as the establishment and growth of a national programme for immunization, and importantly, the eradication of poliomyelitis and maternal and neonatal tetanus. It is also marred by critical challenges which provide a springboard for improvement across all sectors - vaccine stock-outs,strong opposition from certain advocacy groups, and the widely publicized Dengvaxia controversy. Moving forward, with recent surveys having shown that vaccine confidence has begun to improve, these experiences may inform the approaches taken to address vaccine uptake. These lessons from the past highlight the importance of a strong partnership between health leaders and the local community, bearing in mind cultural appropriateness and humility; the engagement of multidisciplinary stakeholders; and the importance of foresight in preparing public health infrastructure for the arrival of a COVID-19 vaccine.

Investigating Adherence to COVID-19 Vaccination and Serum Antibody Concentration among Hospital Workers-The Experience of an Italian Private Hospital.

SARS-CoV-2 transmission has been high, especially among healthcare workers worldwide during the first wave. Vaccination is recognized as the most effective approach to combat the pandemic, but hesitation to get vaccinated represents an obstacle. Another important issue is the duration of protection after administration of the full vaccination cycle. Based on these premises, we conducted a study to evaluate vaccination adherence and the anti-S antibodies levels among hospital workers, from January to March, 2021. To assess adherence, an anonymous questionnaire was used. Anti-S antibody levels were obtained from the monitoring serological sample database. In total, 56.2% of the unvaccinated people did not report a previous infection from COVID-19. Among those who have not been vaccinated, 12.5% showed distrust against the vaccine, 8.3% stated to have received contraindications to the vaccination, and 6.3% did not report any choice. Analyzing anti-S antibody levels, only one person was found to have a value below the lower cut-off, two weeks, and three months after receiving their second dose. One was below the cut-off after two weeks, and then above the same cut-off after three months. The results of our survey should be seen as a stimulus to further sensitize hospital staff to the importance of vaccination and pay attention to anti-S antibody levels monitoring.

HPV vaccine uptake in a school-located vaccination program.

Previous research has implied that while parents may be willing to have their adolescents receive some recommended vaccines via school-located vaccination program (SLVP), they were less likely to agree to the HPV vaccine being administered via SLVP. During an SLVP in a large urban area, 86% of those participating in the program received an HPV vaccine.
