A cross-sectional study on the understanding and attitudes toward influenza and influenza vaccines among different occupational groups in China.

This study aimed to assess the level of knowledge regarding influenza viruses and vaccines among different professional groups to investigate the reasons for vaccine hesitancy. We collected 2190 questionnaires regarding influenza vaccines in China in 2022. The respondents were categorized into the general population (GP), foreign affairs workforce population (FAWP), and veterinary workforce population (VWP) according to their job positions. Linear regression was used to assess the association between multiple factors and influenza vaccination rates. The association between work and influenza vaccination rates was also assessed by grouping different workforce populations. The vaccination rate of the GP was higher than that of the VWP (odds ratio: 1.342, 95% confidence interval: 1.025-1.853), surpassing the rates reported in previous studies. This may be attributed to heightened concerns about infectious diseases influenced by the ongoing coronavirus disease 2019 pandemic. Despite the VWP's more in-depth knowledge of the VWP on zoonotic diseases and their recognition of their importance, there was no significant difference in influenza knowledge among the three populations. This discrepancy contrasts with the observed differences in vaccination rates. Further investigation revealed that, compared with FAWP, the price of vaccines emerged as a primary influencing factor for vaccination rates (odds ratio:0.398, 95%CI; 0.280-0.564). General concerns regarding the protective effects and side effects of vaccines were also noted.

Factors influencing HPV vaccine hesitancy among university students in China: A cross-sectional survey utilizing the 3Cs model.

The HPV vaccine, which has been demonstrated to be an effective method of reducing the risk of developing cervical cancer, is still being underutilized among college students in China. To assess the current status of HPV vaccine hesitancy among college students in Guangdong Province after the COVID-19 outbreak, and to systematically analyze the influencing factors of HPV vaccine hesitancy and construct a prediction model based on the WHO 3Cs model. A cross-sectional web-based survey was conducted in June 2023 among female college students in four cities in Guangdong Province. The data were analyzed using binary logistic regression with a focus on the 3Cs model: Complacency, Convenience, and Confidence. LASSO regression was employed to analyze the variables deemed to be of significance and to construct predictive models. Out of 1399 participants, 86.5% expressed no hesitancy toward HPV vaccination. However, 11.9% exhibited hesitancy, and 1.6% refused vaccination altogether. Factors such as trust in vaccine efficacy, perception of HPV infection risk, price considerations, and constraints like distance or time were significant contributors to hesitancy. Knowledge of the HPV vaccine, socio-demographic characteristics, and the educational level of participants' mothers also played a role in vaccine hesitancy. It is recommended that targeted interventions be implemented within educational institutions with the aim of raising awareness of cervical cancer and HPV vaccines, simplifying the scheduling of vaccination appointments, and increasing affordability through the implementation of strategic purchasing measures or subsidy schemes.

Connect, collaborate and tailor: a model of community engagement through infographic design during the COVID-19 pandemic.

BACKGROUND: Across the globe, racial and ethnic minorities have been disproportionately affected by COVID-19 with increased risk of infection and burden from disease. Vaccine hesitancy has contributed to variation in vaccine uptake and compromised population-based vaccination programs in many countries. Connect, Collaborate and Tailor (CCT) is a Public Health Agency of Canada funded project to make new connections between public health, healthcare professionals and underserved communities in order to create culturally adapted communication about COVID-19 vaccines. This paper describes the CCT process and outcomes as a community engagement model that identified information gaps and created tailored tools to address misinformation and improve vaccine acceptance. METHODS: Semi-structured interviews with CCT participants were undertaken to evaluate the effectiveness of CCT in identifying and addressing topics of concern to underserved and ethnic minority communities. Interviews also explored CCT participants' experiences of collaboration through the development of new partnerships between ethnic minority communities, public health and academic researchers, and the evolution of co-operation sharing ideas and creating infographics. Thematic analysis was used to produce representative themes. The activities described were aligned with the levels of public engagement described in the IAP2 spectrum (International Association for Public Participation). RESULTS: Analysis of interviews (n = 14) revealed that shared purpose and urgency in responding to the COVID-19 pandemic motivated co-operation among CCT participants. Acknowledgement of past harm, present health, and impact of social inequities on public service access was an essential first step in establishing trust. Creating safe spaces for open dialogue led to successful, iterative cycles of consultation and feedback between participants; a process that not only helped create tailored infographics but also deepened engagement and collaboration. Over time, the infographic material development was increasingly directed by community representatives' commentary on their groups' real-time needs and communication preferences. This feedback noticeably guided the choice, style, and presentation of infographic content while also directing dissemination strategies and vaccine confidence building activities. CONCLUSIONS: The CCT process to create COVID-19 vaccine communication materials led to evolving co-operation between groups who had not routinely worked together before; strong community engagement was a key driver of change. Ensuring a respectful environment for open dialogue and visibly using feedback to create information products provided a foundation for building relationships. Finally, our data indicate participants sought reinforcement of close cooperative ties and continued investment in shared responsibility for community partnership-based public health.

The impact of coronavirus disease 2019 (COVID-19) pandemic experiences on attitudes towards vaccinations: on the social, cultural and political determinants of preferred vaccination organization models in Poland.

BACKGROUND: The article describes attitudes towards vaccinations in Poland in relation to issues such as voluntary versus compulsory vaccinations, the method of financing vaccinations, the method of organizing and carrying out vaccinations, the cognitive and educational aspect of vaccines (how to obtain knowledge about vaccines) and the preferred model of work and research on new vaccines. Taking into account these issues, the authors have created four ideal models of preferred vaccination policies: (a) the market model; (b) the state model; (c) the vaccine hesitancy model; and (d) the civic-social model. This perspective makes it possible to better understand and learn about the various motives behind the attitudes of anti-vaccination movements, as well as to notice cracks and divisions among vaccination supporters and their attitudes towards the financing and organization of vaccinations. METHODS: The study was carried out using the CATI method on a representative random-quota sample of Polish society of 1000 people aged 18 and over. The study took age, sex, education and the size of the place of residence into account. Additionally, in the Socio-demographic factors influencing attitudes towards vaccination practices in Poland section, we used the chi-squared test and regression analysis of factors influencing vaccination practices in Poland. PASW Statistics 18 (a version of SPSS) software was used for statistical analysis. Significant correlations were demonstrated at a significance level of 0.05% Pearson. RESULTS: This article has shown that attitudes towards vaccinations are embedded in broader divisions and orientations related to the vision of the social order: the role of the state, the organization of healthcare and payments for vaccinations and medical services, as well as preferred ways of knowledge production in society and work on new vaccines. The political sympathies and the age of the respondents were the most important variables influencing vaccination behaviour. The education of the respondents was less important. CONCLUSIONS: A few years after the peak of the pandemic, the scope of anti-vaccination attitudes in Polish society ranges from 20% of the population (dogmatic anti-vaxxers) to 30% (vaccine hesitancy occurring depending on attitudes towards vaccinations).

Perceptions of COVID-19 Vaccination Among Organ Transplant Recipients.

BACKGROUND: Understanding COVID-19 vaccine hesitancy in organ transplant recipients (OTRs) is critical given clear-albeit attenuated-benefits from vaccination. METHODS: Adult OTRs were surveyed regarding sociodemographic data, medical history, and vaccine-related values. A novel outcome variable called the Vaccine Acceptance Composite Score (VACS) was built as the average Likert score of seven domains of vaccine confidence. To examine its association with several factors and individual adherence to COVID-19 vaccine recommendations, univariable odds ratios and relative operating characteristic areas under the curve (AUC) values were calculated. RESULTS: Of 46 OTRs included, 32.6% identified as female, 13.3% as Black, and 6.77% as Hispanic or Latino/a/x. The median age was 58 years old. 93.5% of patients were kidney transplant recipients, and 63.0% previously had COVID-19. Patients were most concerned about COVID-19 vaccine-associated risks (46.3%), its potential effect on allograft (47.6%), and motives of government officials involved with vaccine policy (55.6%). Politically conservative patients were likelier to have lower VACS, whereas those who lived with someone ≥65 years old were likelier to have higher VACS. The VACS was not significantly associated with race, income, religious beliefs, comorbidities, COVID-19 history, or influenza vaccination status. Higher VACS was associated with ≥3 and ≥4 COVID-19 immunizations. CONCLUSIONS: This study highlighted political beliefs and elderly household members as correlates of vaccine acceptance among OTRs. The VACS may be a useful tool to help standardize multifaceted analyses in vaccination-focused behavioral research. In clinical practice, it could help identify individuals and groups at risk for vaccine hesitancy, who may benefit from tailored outreach and educational interventions.

Influenza vaccine hesitancy among healthcare workers in a Northeastern province in Thailand: Findings of a cross-sectional survey.

BACKGROUND: Healthcare workers (HCWs) are an important target group for influenza vaccination due to their increased risk of infection. However, their uptake remains a challenge. This study aimed to identify and measure influenza vaccine hesitancy among HCWs in Nakhon Phanom province, Thailand. METHODS: A representative cross-sectional survey was conducted during August-September 2020, among 350 HCWs at six hospitals in the province selected by a two-stage cluster sampling using a self-administered questionnaire. HCWs who either delayed getting influenza vaccines, accepted the vaccines but were unsure, or refused the vaccine with doubts were categorized as hesitant. HCWs who accepted the influenza vaccine without any doubts were classified as non-hesitant. Determinants of vaccine hesitancy were identified by a multivariable logistic regression analysis. RESULTS: A total of 338 participants (97%) filled the questionnaires. The mean age of the participants was 37.2 years. Most participants were female (280; 83%), nurses (136; 40%), working at district hospitals (238; 71%), with bachelor's degree (223; 66%), and without any pre-existing chronic medical conditions (264; 78%). Influenza vaccine hesitancy was evident among nearly 60% of the participants (197/338), who had varying patterns of hesitancy. Significant factors of influenza vaccine hesitancy were found to be age above 50 years (adjusted odds ratio [aOR] 3.2, 95% CI 1.3-8.5), fair knowledge of influenza and vaccination (aOR 0.4, 95% CI 0.2-0.8), and negative influence of other HCW (High level-aOR 2.3, 95% CI 1.1-4.8; Moderate level- aOR 2.1, 95% CI 1.1-4.4). CONCLUSION: Influenza vaccine hesitancy was highly prevalent among the Thai HCWs in Nakhon Phanom province. Imparting updated information to the HCW, in combination with positive guidance from influential HCWs in the hospital, may help reduce hesitancy. These data may be useful to the National Immunization Program to design appropriate approaches to target hesitant HCWs in Thailand to improve influenza vaccine coverage.

Strategies to address COVID-19 vaccine hesitancy in First Nations peoples: a systematic review.

BACKGROUND: First Nations peoples face disproportionate vaccine-preventable risks due to social, economic, and healthcare disparities. Additionally, during the COVID-19 pandemic, there was also mistrust and hesitancy about the COVID-19 vaccines among First Nations peoples. These are rooted in factors such as colonial histories, discriminatory medical practices, and unreliable information. OBJECTIVE: To examine strategies to address COVID-19 vaccine hesitancy among First Nations peoples globally. METHODS: A systematic review was conducted. Searches were undertaken in OVID MEDLINE, OVID EMBASE, OVID PsycINFO, CINAHL, and Informit. Searches were date limited from 2020. Items included in this review provided primary data that discussed strategies used to address COVID-19 vaccine hesitancy in First Nations peoples. RESULTS: We identified several key strategies across four countries - Australia, the USA, Canada, and Guatemala in seventeen papers. These included understanding communities' needs, collaborating with communities, tailored messaging, addressing underlying systemic traumas and social health gaps, and early logistics planning. CONCLUSION: The inclusion of First Nations-centred strategies to reduce COVID-19 vaccine hesitancy is essential to delivering an equitable pandemic response. Implementation of these strategies in the continued effort to vaccinate against COVID-19 and in future pandemics is integral to ensure that First Nations peoples are not disproportionately affected by disease.

Main findings In this review, we identified seventeen studies detailing five key strategies to reduce COVID-19 vaccine hesitancy among First Nations Peoples.Added knowledge First Nations-centred strategies to reduce COVID-19 vaccine hesitancy were: understanding communities' needs, collaboration with communities, tailored messaging, logistics planning and addressing the underlying systemic trauma experienced by First Nations peoples when accessing healthcare.Global health impact for policy and action First Nations-centred strategies must be included in the continued effort to vaccinate against COVID-19 and other future outbreaks to ensure that First Nations peoples are not disproportionately affected.

Meeting the challenge of vaccine hesitancy.

Vaccination is a cornerstone of public health, but vaccine hesitancy poses significant challenges as highlighted during the COVID-19 pandemic. Addressing the challenge requires healthcare professionals to effectively counter misinformation. They have a pivotal role in fostering trust and promoting evidence-based vaccine recommendations, with tailored communication strategies and community engagement initiatives. Legislation, policy interventions, research, innovation, and technology are needed to enhance vaccine uptake and ensure equitable access. Integration of vaccination into routine healthcare is paramount for public health protection against emerging infectious threats.

Development and validation of the COVID-19 vaccine beliefs scale for the Chinese population.

BACKGROUND: At present, there is no culturally appropriate scale designed to measure Chinese people's attitudes and beliefs about COVID-19 vaccines. Understanding people's attitudes and beliefs about vaccines can help policy makers and health care professionals better evaluate local beliefs to increase vaccine coverage and minimize COVID-19 vaccine hesitancy. METHODS: We developed a COVID-19 vaccine attitudes and beliefs scale comprising items based on qualitative research data. We then conducted an explorative and confirmatory factor analysis using data from two online sources. RESULTS: The 26-item vaccine belief scale includes a five-factor model: vaccine benefit (VB), vaccine concern (VC), observing others' reactions to vaccination (VR), the influence of authority and others toward vaccination (VI), and common sense about vaccination (VS). The multivariate analysis results showed that VB (OR = 1.065, 95% CI 1.035-1.097), VR (OR = 0.878, 95% CI 0.832-0.927), and VS (OR = 1.076, 95% CI 1.032-1.122) were associated with the intention to receive the vaccine. These results implied that VC (OR = 0.957, 95% CI 0.928-0.987) could predict the choice not to be vaccinated. A correlation between beliefs about vaccines and conspiracy theories and fear of COVID-19 was also found and discussed. CONCLUSIONS: These findings suggest that the locally designed and culturally sensitive scale has good reliability and validity. The questionnaire provides researchers with a standardized assessment tool to measure Chinese people's beliefs about the COVID-19 vaccine.

Healthcare Provider Experiences With Unvaccinated COVID-19 Patients: A Qualitative Study.

IMPORTANCE: In the setting of an active pandemic the impact of public vaccine hesitancy on healthcare workers has not yet been explored. There is currently a paucity of literature that examines how patient resistance to disease prevention in general impacts practitioners. OBJECTIVES: The COVID-19 pandemic created unprecedented healthcare challenges with impacts on healthcare workers' wellbeing. Vaccine hesitancy added complexity to providing care for unvaccinated patients. Our study qualitatively explored experiences of healthcare providers caring for unvaccinated patients with severe COVID-19 infection in the intensive care setting. DESIGN: We used interview-based constructivist grounded theory methodology to explore experiences of healthcare providers with critically ill unvaccinated COVID-19 patients. SETTING AND PARTICIPANTS: Healthcare providers who cared for unvaccinated patients with severe COVID-19 respiratory failure following availability of severe acute respiratory syndrome coronavirus 2 vaccines were recruited from seven ICUs located within two large academic centers and one community-based hospital. We interviewed 24 participants, consisting of eight attending physicians, seven registered nurses, six critical care fellows, one respiratory therapist, one physiotherapist, and one social worker between March 2022 and September 2022 (approximately 1.5 yr after the availability of COVID-19 vaccines in Canada). ANALYSIS: Interviews were recorded, transcribed, de-identified, and coded to identify emerging themes. The final data was analyzed to generate the thematic framework. Reflexivity was employed to reflect upon and discuss individual pre-conceptions and opinions that may impact collection and interpretation of the data. RESULTS: Healthcare providers maintained dedication toward professionalism during provision of care, at the cost of suffering emotional turmoil from the pandemic and COVID-19 vaccine hesitancy. Evolving sources of stress associated with vaccine hesitancy included ongoing high volumes of critically ill patients, resource shortages, and visitation restrictions, which contributed to perceived emotional distress, empathy loss, and professional dissatisfaction. As a result, there were profound personal and professional consequences for healthcare professionals, with perceived impacts on patient care. CONCLUSIONS: Our study highlights struggles of healthcare providers in fulfilling professional duties while navigating emotional stressors unique to vaccine hesitancy. System-based interventions should be explored to help providers navigate biases and moral distress, and to foster resilience for the next major healthcare system strain.

COVID-19 vaccination receipt and intention to vaccinate among adults with disabilities and functional limitations, United States.

BACKGROUND: People with disabilities are at increased risk for severe COVID-19 health outcomes and face barriers accessing COVID-19 vaccines. The aim of this study is to examine receipt of ≥ 1 dose of the COVID-19 vaccine, intention to vaccinate in the future, and reasons for not vaccinating among people with disabilities and functional limitations using a large, nationally representative dataset of adults in the United States. METHODS: Data were analyzed from the Census Bureau's Household Pulse Survey (14-26 April 2021, n = 68,913). Separate logistic regression models were conducted to examine the association between each disability (vision, hearing, cognition and mobility), overall disability status, and functional status on ≥1 dose COVID-19 vaccination receipt and intention to vaccinate. Furthermore, reasons for not getting vaccinated were examined among those with disabilities or functional limitations. RESULTS: Approximately 13% of adults reported having a disability, and almost 60% reported having some or a lot of functional limitations. Over 65% of adults with disabilities had received ≥1 dose of COVID-19 vaccines, compared to 73% among adults without disabilities (adjusted prevalence ratio = 0.94). Among adults with disabilities, those who were younger, had lower educational attainment and income, did not have insurance and had a prior history of COVID-19 were less likely to get vaccinated or intend to get vaccinated than their respective counterparts. The main reasons for not getting vaccinated were concerns about possible side effects (52.1%), lack of trust in COVID-19 vaccines (45.4%) and lack of trust in the government (38.6%). DISCUSSION AND CONCLUSION: Efforts to ensure high and equitable vaccination coverage include working with communities to strengthen the message that the vaccine is safe and effective, educating health professionals about the need to recommend and promote vaccines, and making vaccination sites more accessible for people who need additional accommodations.

Understanding herpes zoster vaccine hesitancy and information asymmetry: a qualitative study in China.

Background: Herpes zoster is more prevalent among the older adult due to the age-related immune decline, leading to significant pain and complications. Although vaccination effectively prevents viral infections, vaccine hesitancy remains a major barrier to achieving high vaccination rates.To address this, we conducted a qualitative survey using Vaccine Hesitancy Determinants Matrix and 5C model to understand and improve vaccination rates in this group. Methods: Descriptive qualitative research design based on the philosophical underpinnings of naturalistic inquiry and purposive sampling methodology was conducted on adults aged 50 and above, as well as community health workers. Data were collected through semi-structured, in-depth personal interviews. The interview outline was constructed following a comprehensive review of the literature and consideration of the theoretical framework. Results: Seventeen adults over 50 years and four community healthcare workers were included in this study. The study found that information asymmetry in immunization planning was evident at all stages of vaccine supply, dissemination and demand. The main manifestations included limited access to authoritative information, insufficient community awareness of herpes zoster as a route of vaccination, insufficient vocational training, significant gaps in vaccine knowledge, and high levels of complacency among individual residents. Conclusion: Herpes zoster vaccine hesitancy is prevalent among middle-aged and older adults in China due to information asymmetry, vaccine complacency, inadequate community services, and other multiple layers of factors. Public health strategies should aim to reduce cognitive biases and information gaps by disseminating diverse and credible vaccine information through social media, medical institutions, and offline channels to promote higher vaccination rates.

Perceptions of COVID-19 vaccination and factors influencing COVID-19 vaccine acceptance among indigenous peoples in Quebec, Canada: Insights from a facebook posts and comments analysis.

Vaccination rates in Canada tend to be lower among Indigenous peoples than the rest of the population. The COVID-19 pandemic provided an unprecedented opportunity to better understand Indigenous perceptions about vaccination. The aim of this study was to explore perceptions of COVID-19 vaccine and other factors influencing COVID-19 vaccine acceptance as evidenced by public posts and comments on Facebook by Indigenous peoples in Quebec, Canada. We collected data on 95 Facebook pages or groups used by Indigenous peoples in Quebec between November 1, 2020, to June 15, 2021. To identify posts relating to COVID-19 vaccination, a keyword search ("vaccination," "vaccine," "shot," "does," "Moderna," "Pfizer") was carried out in English and French in the search bar of each Facebook page/group. Results show that First Nations peoples and Inuit in Quebec had important concerns about the usefulness, safety and effectiveness of COVID-19 vaccine. They also expressed fear of being used as test subjects for the rest of the population. Motivations mentioned by First Nations peoples and Inuit to get vaccinated against COVID-19 included to travel again and return to normal life with their loved ones, and the desire to protect the most vulnerable in their communities, especially Elders. Results show that Indigenous health care professionals were considered as reliable and trustful source of information regarding COVID-19, and that seeing role models being vaccinated build confidence and foster acceptance of the vaccine. Culturally adapted messages and vaccination campaigns by and for Indigenous peoples appear to be key to building trust toward COVID-19 vaccination.

Level of hesitation of parents about childhood vaccines and affecting factors: a cross-sectional study in Turkey.

BACKGROUND: Hesitancy rates for childhood vaccines are increasing on a global scale. It was reported in previous studies that many factors affect vaccine hesitancy. The present study was designed to determine the prevalence of childhood vaccination hesitancy in parents and to determine the factors affecting it. METHODS: This descriptive, cross-sectional study was conducted with 350 parents who had at least one child aged two years and younger, who applied to Family Health Centers in the city of Mardin in the Southeastern Anatolia Region of Turkey, between January and March 2022. The "Parental Attitudes Towards Childhood Vaccines (PATCV) Questionnaire" was used to collect the data, which were analyzed by using the SPSS (Statistical Package for Social Sciences) for Windows 22.0 program. The Logistic Regression Analysis was used to determine the factors affecting parental attitudes toward childhood vaccines. RESULTS: A total of 32.0% of the parents were found to be hesitant about vaccinations and 3.4% did not have at least one vaccination for their children. Significant relationships were detected between income status, education status, thoughts about vaccinations, parents having adult vaccinations, hesitant to have self-vaccination, considering vaccine necessary, and parental attitudes towards childhood vaccinations (p < 0.05). According to the Regression Analysis, parents who had adult vaccinations had reduced hesitation about childhood vaccines 0.506 times (p = 0.032; OR = 0.506; 95%CI = 0.271-0.943). Considering the vaccine necessary reduced the hesitation about childhood vaccines by 0.440 times (p = 0.011; OR = 0.440; 95%CI = 0.234-0.828). CONCLUSIONS: The hesitations of parents about childhood vaccines were found to be high. The reasons for vaccine hesitancy must be examined in detail and strategies must be developed in this regard.

Description of vaccination coverage and hesitancy obtained by epidemiological survey of children born in 2017-2018, in Belo Horizonte and Sete Lagoas, Minas Gerais, Brazil.

OBJECTIVE: To describe vaccination coverage and hesitation for the basic children's schedule in Belo Horizonte and Sete Lagoas, Minas Gerais state, Brazil. METHODS: Population-based epidemiological surveys performed from 2020 to 2022, which estimated vaccine coverage by type of immunobiological product and full schedule (valid and ministered doses), according to socioeconomic strata; and reasons for vaccination hesitancy. RESULTS: Overall coverage with valid doses and vaccination hesitancy for at least one vaccine were, respectively, 50.2% (95%CI 44.1;56.2) and 1.6% (95%CI 0.9;2.7), in Belo Horizonte (n = 1,866), and 64.9% (95%CI 56.9;72.1) and 1.0% (95%CI 0.3;2.8), in Sete Lagoas (n = 451), with differences between socioeconomic strata. Fear of severe reactions was the main reason for vaccination hesitancy. CONCLUSION: Coverage was identified as being below recommended levels for most vaccines. Disinformation should be combated in order to avoid vaccination hesitancy. There is a pressing need to recover coverages, considering public health service access and socioeconomic disparities. MAIN RESULTS: Vaccination coverage of children up to 4 years old was 50.2% in Belo Horizonte, and 64.9% in Sete Lagoas. Fear of severe reactions and believing that vaccination against eradicated diseases is unnecessary were the main reasons for vaccination hesitancy. IMPLICATIONS FOR SERVICES: Recovery of high vaccination coverage among children, considering public health service access conditions and socioeconomic inequities. Acting on reasons for hesitancy that can assist in targeting actions. PERSPECTIVES: The multifactorial context of vaccination hesitancy demands the development of health education strategies to raise awareness about child immunization.

Pregnant individuals perspectives towards receiving COVID-19 vaccination during their pregnancy: an in-depth qualitative study.

Introduction: Pregnant individuals have an increased risk of severe illness from coronavirus disease 2019 (COVID-19) infection. Vaccination is an effective strategy to prevent severe illness and complications for pregnant individuals. Pregnant individuals are often excluded from research and remain hesitant to receive vaccination against COVID-19. It is pivotal to study factors related to vaccine uptake and hesitancy among pregnant individuals. We studied barriers and facilitators for pregnant individuals choice and motivation regarding vaccination against COVID-19 during pregnancy to aid future pregnant individuals in their decision to vaccinate against various infectious agents. Methods: In this qualitative study, pregnant individuals were interviewed between October 2021 and January 2022 using a semi-structured approach. A topic list was used to explore their feelings, perceptions and ideas regarding vaccination against COVID-19 during pregnancy. Interviews were transcribed verbatim and thematic analyses was performed using MAX QDA. Results: After nine interviews, saturation was reached. Three main themes were identified that influenced pregnant individuals choice and motivation regarding vaccination: health consequences, ambiguity of information and societal motivation. Health consequences mainly concerned the effect for their offspring, and the unknown long-term effects of COVID-19 vaccination. The advice from the Dutch institute for Public Health and Environment changed from not vaccinating pregnant individuals after release of the developed vaccine, to routinely vaccinating all pregnant individuals after research data were available from the United States of America (USA). This change of policy fuelled doubt and confusion for vaccination. Arguments in favor of vaccination from the social perspective were specific behaviour rules and restrictions due to the pandemic. E.g. without vaccination people were unable to travel abroad and having to take a COVID-19 test every time entering a public place. Conclusion: Pregnant individuals need clear, unambiguous information concerning health consequences, short- and long-term, particularly for their offspring, in the decision-making process regarding COVID-19 vaccination. Additionally, the societal perspective needs to be addressed. Besides the aforementioned themes, general counselling should focus on misperceptions of vaccine safety and the role of misinformation which are also important in the non-pregnant population. This study underlines the importance of including pregnant individuals in research programs to obtain specific information targeted to their needs.

Confidence and barriers: Analysis of factors associated with timely routine childhood vaccination in Canada during the COVID-19 pandemic.

Routine childhood vaccination is a crucial component of public health in Canada and worldwide. To facilitate catch-up from the global decline in routine vaccination caused by the COVID-19 pandemic, and toward the ongoing pursuit of coverage goals, vaccination programs must understand barriers to vaccine access imposed or exacerbated by the pandemic. We conducted a regionally representative online survey in January 2023 including 2036 Canadian parents with children under the age of 18. We used the COM-B model of behaviour to examine factors influencing vaccination timeliness during the pandemic. We assessed Capability with measures of vaccine understanding and decision difficulty, and Motivation with a measure of vaccine confidence. Opportunity was assessed through parents' self-reported experience with barriers to vaccination. Twenty-four percent of surveyed parents reported having missed or delayed one of their children's scheduled routine vaccinations since the beginning of the pandemic, though most parents reported having either caught up or the intention to catch up soon. In the absence of opportunity barriers, motivation was associated with timely vaccination for children aged 0-4 years (aOR = 1.81, 95 % CI: 1.14-2.84). However, experience with one or more opportunity barriers, particularly clinic closures and difficulties getting an appointment, eliminated this relationship, suggesting perennial and new pandemic-associated barriers are a critical challenge to vaccine coverage goals in Canada.

Canadian health care providers' and education workers' hesitance to receive original and bivalent COVID-19 vaccines.

BACKGROUND: The demand for COVID-19 vaccines has diminished as the pandemic lingers. Understanding vaccine hesitancy among essential workers is important in reducing the impact of future pandemics by providing effective immunization programs delivered expeditiously. METHOD: Two surveys exploring COVID-19 vaccine acceptance in 2021 and 2022 were conducted in cohorts of health care providers (HCP) and education workers participating in prospective studies of COVID-19 illnesses and vaccine uptake. Demographic factors and opinions about vaccines (monovalent and bivalent) and public health measures were collected in these self-reported surveys. Modified multivariable Poisson regression was used to determine factors associated with hesitancy. RESULTS: In 2021, 3 % of 2061 HCP and 6 % of 3417 education workers reported hesitancy (p < 0.001). In December 2022, 21 % of 868 HCP and 24 % of 1457 education workers reported being hesitant to receive a bivalent vaccine (p = 0.09). Hesitance to be vaccinated with the monovalent vaccines was associated with earlier date of survey completion, later receipt of first COVID-19 vaccine dose, no influenza vaccination, and less worry about becoming ill with COVID-19. Factors associated with hesitance to be vaccinated with a bivalent vaccine that were common to both cohorts were receipt of two or fewer previous COVID-19 doses and lower certainty that the vaccines were safe and effective. CONCLUSION: Education workers were somewhat more likely than HCP to report being hesitant to receive COVID-19 vaccines but reasons for hesitancy were similar. Hesitancy was associated with non-receipt of previous vaccines (i.e., previous behaviour), less concern about being infected with SARS-CoV-2, and concerns about the safety and effectiveness of vaccines for both cohorts. Maintaining inter-pandemic trust in vaccines, ensuring rapid data generation during pandemics regarding vaccine safety and effectiveness, and effective and transparent communication about these data are all needed to support pandemic vaccination programs.
