Religion and Measles Vaccination in Indonesia, 1991-2017

Faith and vaccination: a scoping review of the relationships between religious beliefs and vaccine hesitancy

BACKGROUND

Throughout history, vaccines have proven effective in addressing and preventing widespread outbreaks, leading to a decrease in the spread and fatality rates of infectious diseases. In a time where vaccine hesitancy poses a significant challenge to public health, it is important to identify the intricate interplay of factors exemplified at the individual and societal levels which influence vaccination behaviours. Through this analysis, we aim to shed new light on the dynamics of vaccine hesitancy among religious groups, contributing to the broader effort to promote vaccine uptake, dispel misunderstandings, and encourage constructive dialogue with these groups.

METHODS

We used the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) using the 20-point checklist to guide this review. The inclusion criteria for our study were that the literature should be in English, concerned with vaccine hesitancy as the focus of study, study the impact religiosity or religious beliefs as either an outcome or control variable, concerning population levels, and be peer-reviewed.

RESULTS

We analysed 14 peer-reviewed articles that included components related to religiosity or religious beliefs and their impact on vaccine hesitancy published until September 2023. All the articles were published in approximately the last decade between 2012 and 2023, with only 4 of the articles published before 2020. Out of the 14 studies included in our review, twelve utilized quantitative methods, while the remaining two employed qualitative approaches. Among the studies included in our analysis, we found various approaches to categorizing religious belief and identity. In most studies when religion is uniformly regarded as the sole determinant of vaccine hesitancy, it consistently emerges as a significant factor in contributing to vaccine hesitancy. All studies in our review reported sociodemographic factors to some degree related to vaccine hesitancy within their sample populations. Our analysis underscored the need for nuanced approaches to addressing vaccine hesitancy among religious groups.

CONCLUSION

Vaccine hesitancy is a complex issue and driven by a myriad of individual and societal factors among which religious beliefs is commonly associated to be a driver of higher levels among populations.

Parental vaccine hesitancy and acceptance of a COVID-19 vaccine: An internet-based survey in the US and five Asian countries

COVID-19 vaccination rates for children globally are relatively low. This study aimed to investigate parental vaccine hesitancy and parents' acceptance of a COVID-19 for their children for their children in the United States, China, Taiwan, India, Indonesia, and Malaysia.We analyzed data from an opt-in, internet-based cross-sectional study (n = 23,940). Parents were asked about their acceptance of a COVID-19 vaccine for their children, and if they would accept the vaccine with different risk and effectiveness profiles for themselves. Poisson regression was used to generate prevalence ratios (PR) of the relationship between vaccine acceptance for a child and vaccine profile, by country and waves and overall. Between August 2020 and June 2021, COVID-19 vaccine acceptance for children decreased in the United States (89% to 72%) and Taiwan (79% to 71%), increased in India (91% to 96%) and Malaysia (81% to 91%), and was stable in Indonesia (86%) and China (at 87%-90%). Vaccine risk and effectiveness profiles did not consistently affect parent's acceptance of a COVID-19 vaccine for their children. Instead, being not hesitant was a large driver of vaccine acceptance (PR: 1.24, 95% CI: 1.14, 1.36). Adolescent COVID-19 vaccination have already been established in many high and middle-income countries, but our study suggests that there is a movement of vaccine hesitancy which could impede the success of future pediatric and adolescent COVID-19 vaccination programs.

Vaccine hesitancy and equity: lessons learned from the past and how they affect the COVID-19 countermeasure in Indonesia

INTRODUCTION

Indonesia has made progress in increasing vaccine coverage, but equitable access remains challenging, especially in remote areas. Despite including vaccines in the National Immunization Program (NIP), coverage has not met WHO and UNICEF targets, with childhood immunization decreasing during the COVID-19 pandemic. COVID-19 vaccination has also experienced hesitancy, slowing efforts to end the pandemic.

SCOPE

This article addresses the issue of vaccine hesitancy and its impact on vaccination initiatives amidst the COVID-19 pandemic. This article utilizes the vaccine hesitancy framework to analyze previous outbreaks of vaccine-preventable diseases and their underlying causes, ultimately providing recommendations for addressing the current situation. The analysis considers the differences between the pre-pandemic circumstances and the present and considers the implementation of basic and advanced strategies.

KEY FINDINGS AND CONCLUSION

Vaccine hesitancy is a significant challenge in the COVID-19 pandemic, and public health campaigns and community engagement efforts are needed to promote vaccine acceptance and uptake. Efforts to address vaccine hesitancy promote trust in healthcare systems and increase the likelihood of individuals seeking preventive health services. Vaccine hesitancy requires a comprehensive, culturally sensitive approach that considers local contexts and realities. Strategies should be tailored to specific cultural and societal contexts and monitored and evaluated.

Influence of the COVID-19 pandemic on caregiver beliefs and experiences of routine childhood immunisation in Indonesia

The COVID-19 pandemic contributed to significant health services declines in South-East Asia including Indonesia, which experienced a decline in routine immunisation of children. This study investigated the influence of the pandemic on the beliefs and experiences of caregivers of children related to routine immunisation. This study involved a cross-sectional survey among 1399 caregivers of children aged 0-24 months in Central Java and West Nusa Tenggara provinces from March-April 2022. Data on beliefs and experiences of childhood immunizations were captured using core items from the WHO/UNICEF Behavioural and Social Drivers of Immunization (BeSD) survey. Bivariate and multivariate logistic regression analyses identified factors associated with uptake of routine immunisations. While nearly all caregivers (95.7%) reported wanting their child to receive all recommended routine immunisations, only 40.3% of children aged 2-24 months were up-to-date with all vaccines for age. Factors associated with up-to-date included higher parental education (aOR: 1.76, 95% CI 1.02-3.05), higher household income (aOR: 1.54, 95% CI 1.09-2.18), and caregivers who found it moderately or very easy to get immunisations (aOR: 2.26/2.22, 95% CI 1.06-4.83/1.06-4.69). Recovery efforts should prioritise responding to the factors associated with immunisation status (e.g., perceived ease of access) and on families experiencing disadvantage (e.g., caregivers with lower education and household income) to ensure protections against future outbreaks that are responsive to the context-specific needs and priorities of districts and communities.

Barriers to measles mumps rubella vaccine acceptance in the three southern border provinces of Thailand

Purpose

This qualitative study utilizing phenomenological methodology aimed to depict parental measles mumps rubella (MMR) vaccine acceptance through the work experiences of health personnel.

Materials and Methods

Twenty-two public health workers working as vaccination providers in the three southern border provinces of Thailand were recruited. In-depth, face-to-face, semi-structured interviews were conducted. Data were analyzed using thematic analysis.

Results

Four main themes emerged: (1) religious beliefs, (2) personal disagreements, (3) fear and mistrust regarding potential vaccine side effects, and (4) misperceptions about the potential severity of measles. Four subthemes were identified: (1) haram (prohibited), (2) the will of Allah, (3) spousal disagreement, and (4) disagreement from a religious leader. The results of this study indicated that perceived religious prohibition was the most important reason for refusing to vaccinate among Muslim parents. Vaccine-hesitant parents were concerned that the vaccine might contain gelatin derived from pig products. Also, halal certification of the vaccine was required from Muslim parents to ensure that vaccine has been approved for Muslims. Meanwhile, a lack of knowledge and positive attitudes concerning immunizations of vaccine-hesitant parents were also found as predominant reasons for incomplete childhood immunizations in the deep south of Thailand.

Conclusion

Health education and engagement by religious leaders to endorse the vaccination and bridge the gap between religious beliefs and vaccine acceptance is needed to overcome this issue. This study findings could be effectively applied to improve vaccination uptake in a Muslim majority context.

Barriers to and Facilitators of Hepatitis B Vaccination among the Adult Population in Indonesia: A Mixed Methods Study

To reach the goals of the Global Hepatitis Elimination 2030 program, Indonesia is now preparing a new regulation for hepatitis B vaccinations for adult population. This study aimed to determine the factors influencing vaccine uptake for hepatitis B in the adult population, and identify barriers to, and facilitators of, hepatitis B vaccination programmes. An explanatory sequential mixed methods design was implemented in this study. We conducted a survey involving 893 participants in the general population followed by 14 in-depth interviews with health providers. The survey found that only 15% (95% confidence interval 13-18%) of participants received at least one dose of the hepatitis B vaccine. Factors associated with vaccine uptake were, living in Yogyakarta compared to living in Aceh, having secondary and higher education compared to primary education, working as a health worker compared to working in other sectors, and having health insurance that covered hepatitis B vaccination compared to not having such health insurance. Our qualitative study also identified several barriers to the adult hepatitis B vaccination programme in Indonesia such as the high cost of vaccination, lack of vaccine availability in certain areas, limited human resources to implement the hepatitis B vaccination programme, and the ineffective dissemination of hepatitis B vaccination. This study highlights that accessibility and affordability of vaccinations are important determinants of vaccination uptake that should be taken into account when planning vaccination campaigns.

Political Partisanship, Trust, and Attitudes toward COVID-19 Vaccines in Indonesia

CONTEXT

This study examines the extent to which political partisanship-measured as support for either the incumbent candidate for Indonesia's presidency, Joko Widodo (popularly known as Jokowi), or for Jokowi's challenger, Prabowo-affects individuals' risk perception of COVID-19 and COVID-19 vaccine hesitancy and refusal as well as beliefs about the safety and efficacy of the COVID-19 vaccine.

METHODS

The authors performed multinomial logistic and ordinary least squares regression analyses on a nationally representative sample of a national survey on public trust in COVID-19 vaccines and vaccinations that was conducted in December 2020.

FINDINGS

Individuals who voted for Prabowo in the 2019 presidential election were more likely to have a lower level of willingness and a higher level of hesitancy to get the COVID-19 vaccine than those who cast their ballot for Jokowi as the Indonesian president.

CONCLUSIONS

Political partisanship does matter in shaping individuals' hesitancy or refusal to receive the COVID-19 vaccine in Indonesia. The effect of partisanship is also significant in shaping individuals' trust in the efficacy and safety of the COVID-19 vaccine, but it is not significantly associated with individuals' risk perceptions.

Mitigating Vaccine Hesitancy and Building Trust to Prevent Future Measles Outbreaks in England

Measles, a highly infectious respiratory viral infection associated with severe morbidity and mortality, is preventable when coverage with the highly effective measles, mumps and rubella vaccine (MMR) is ≥95%. Vaccine hesitancy is responsible for measles outbreaks in countries where measles had previously been eliminated, including in England, and is one of the ten threats to global public health identified by the World Health Organization (WHO). Official administrative 2012-2021 data on measles incidence and MMR coverage in England were reviewed alongside a scoping literature review on factors associated with MMR uptake in England. Whilst measles incidence has reduced significantly since 2012, sporadic measles outbreaks in England have occurred with geographic disparities and variations in MMR coverage. Over the last decade, MMR uptake has fallen across all regions with no area currently reaching the WHO target of 95% coverage of both doses of MMR necessary for herd immunity. Factors associated with MMR coverage overlap with the 3C (convenience, complacency and confidence) model of vaccine hesitancy. The COVID-19 pandemic has reinforced pre-existing vaccine hesitancy. Increasing MMR uptake by reducing vaccine hesitancy requires allocated funding for area-based and targeted domiciliary and community-specific immunisation services and interventions, public health catch-up campaigns and web-based decision aid tools.

Less than one-fifth of Ethiopian children were vaccinated for measles second dose; evidence from the Ethiopian mini demographic and health survey 2019

Ethiopia introduced the measles second dose vaccine from the routine expanded immunization program in 2018. Shreds of evidence are scarce on the measles second dose vaccination coverage and its associated factors in Ethiopia. We aimed to assess the measles second dose vaccination coverage and associated factors in Ethiopia using the recent Ethiopian Mini Demographic and Health Survey (EMDHS) 2019 data. An in-depth secondary data analysis was conducted based on the Ethiopian mini demographic and health survey 2019 data; which was a cross-sectional survey targeted on key indicators of maternal and child health. A weighted sample of 965 children was included in the analysis. A multi-level mixed effect logistics regression model was fitted. Adjusted Odds Ratio (AOR) with 95 %CI was reported for statistically significant variables. The measles second dose coverage was 12.36 % (95 %CI = 10.89, 15.44). Not vaccinated for the third dose of pentavalent vaccine (Penta 3) (AOR = 0.60, 95 %CI: 0.37, 0.95), age of the child [13 to 23 months (AOR = 2.14, 95 %CI: 1.05, 4.36), 24 to 36 months (AOR = 2.58, 95 %CI: 1.32, 5.05)], household head educational status [no education (AOR = 0.51,95 %CI: 0.26, 0.99), primary (AOR = 0.44, 95 %CI: 0.23, 0.85)], and living in south nation, nationalities and peoples region (SNNPR) (AOR = 2.83,95 %CI: 1.12, 7.11) were significantly associated with measles second dose vaccination coverage. Measles second dose vaccination coverage was low in Ethiopia. Age of the child, being vaccinated for the Penta 3, educational status of the household head, and region of residence were significant determinants of measles second dose vaccination coverage.

Understanding hepatitis B vaccination willingness in the adult population in Indonesia: a survey among outpatient and healthcare workers in community health centers

Aim

This study aimed to assess factors associated with the willingness to be vaccinated against hepatitis B among Indonesia’s adult population, considering cultural and geographic differences by analysing the two provinces of Aceh and Yogyakarta.

Subject and methods

An institution-based cross-sectional survey was conducted in 16 community health centres. A multivariable logistic regression model stratified by province was employed to assess variables associated with the willingness to receive hepatitis B vaccination.

Results

We found that participants from Yogyakarta more often had a higher knowledge and risk perception of hepatitis B and were more often willing to get vaccinated than participants from Aceh. We also found that a high-risk perception of hepatitis B infection was associated with the willingness to be vaccinated against hepatitis B in participants from both Aceh and Yogyakarta. Furthermore, in Yogyakarta, a fair and high knowledge of hepatitis B infection and vaccination, being female, and having health insurance covering hepatitis B vaccination costs were associated with the willingness to be vaccinated. In Aceh, health care workers in high-risk units for hepatitis B had a higher willingness to be vaccinated than those who were not high-risk health care workers.

Conclusion

Given the different factors associated with the willingness to be vaccinated against hepatitis B in Aceh and Yogyakarta, this study also highlights the need of a locally adjusted, culture-based approach to improve the hepatitis B vaccination programme.

Childhood immunization and age-appropriate vaccinations in Indonesia

Background

Childhood immunization is a cost-effective way to protect individuals against communicable diseases. However, although there is a large literature on childhood immunization in Indonesia, there is a paucity of research on the age-appropriateness on measles and DTwP-3 vaccination, and the inequities in immunization coverage across Indonesia.

Methods

In this paper, using seven waves of data from the nationally representative Indonesia Demographic and Health Surveys (DHS) covering the period 1991- 2017, we empirically analyse the socio-economic and demographic factors influencing the uptake of four routine vaccines (BCG, Polio-3, DTwP-3, and Measles). Specifically, using multivariate regression analysis, we identify the socio-economic and demographic factors influencing childhood immunization coverage. We further analyse the socio-economic and demographic correlates of the age-appropriateness of the measles and DTwP-3 vaccination coverage.

Results

Our findings show that parental education and use of healthcare services are strong predictors of full immunization and age-appropriate vaccinations. This study also finds evidence of spatial heterogeneity in both full immunization rates and age-appropriate vaccinations for measles and DTwP-3 vaccines.

Conclusions

Our analysis finds that despite an improvement in the timing of vaccinations over the last two decades, a significant proportion of children continue to receive their measles and DTwP vaccinations age inappropriately. In particular, we find that maternal education and maternal engagement with healthcare services are critical in improving age appropriateness of vaccinations. From a policy perspective, these results call for concerted efforts by policy makers to address regional gaps in access to health services and immunization coverage, as well as to improve the age-appropriateness of vaccination.

[The determinants of SARS-CoV-2 vaccine hesitancy in a rural area of an Indonesia-Philippines border island: A mixed-method study]

Background

The SARS-CoV-2 vaccination program campaign has been underway in Indonesia for people aged ≥ 18 years. The program's success can be hampered by vaccine hesitancy in communities. This study aims to elucidate the determinants of SARS-CoV-2 vaccine hesitancy in a rural area of the Indonesia-Philippines border island Sangihe.

Methods

A mixed-methods study was conducted; a quantitative part involving a cross-sectional survey was carried out among participantes aged ≥ 18 years to determine the prevalence and determinants of SARS-CoV-2 vaccine hesitancy. The qualitative part involved in-depth interviews to explore the perceptions towards the SARS-CoV-2 vaccine.

Result

Among 557 participantes, the prevalence of vaccine hesitancy was 63.9% (95% CI: 59.8-67.9). In the adjusted analysis, three factors affected vaccine hesitancy: education (aOR: 0.40; 95% CI: 0.22-0.70), knowledge of the SARS-CoV-2 vaccine (aOR: 2.17; 95% CI: 1.41-3.34) and willingness to pay (aOR: 0.12; 95% CI: 0.07-0.20). The majority of reasons for refusing the vaccine included doubt regarding its safety and effectiveness, the fear of side effects, lack of information regarding the vaccine and local Christians' religious beliefs.

Conclusion

This study found that most adults in the area were hesitant about the SARS-CoV-2 vaccine. Lack of knowledge, a low level of education and misinformation were factors that greatly affected vaccination hesitancy. The government, by involving religious leaders, is expected to pay serious attention to the dissemination of accurate and convincing information to the public regarding the safety and importance of the SARS-CoV-2 vaccine.

Religious affiliation as a driver of immunization coverage: Analyses of zero-dose vaccine prevalence in 66 low- and middle-income countries

Background

The literature on the association between religion and immunization coverage is scant, mostly consisting of single-country studies. Analyses in low and middle-income countries (LMICs) to assess whether the proportions of zero-dose children vary according to religion remains necessary to better understand non-socioeconomic immunization barriers and to inform interventions that target zero-dose children.

Methods

We included 66 LMICs with standardized national surveys carried out since 2010, with information on religion and vaccination. The proportion of children who failed to receive any doses of a diphtheria-pertussis-tetanus (DPT) containing vaccine - a proxy for no access to routine vaccination or "zero-dose" status - was the outcome. Differences among religious groups were assessed using a test for heterogeneity. Additional analyses were performed controlling for the fixed effect of country, household wealth, maternal education, and urban-rural residence to assess associations between religion and immunization.

Findings

In 27 countries there was significant heterogeneity in no-DPT prevalence according to religion. Pooled analyses adjusted for wealth, maternal education, and area of residence showed that Muslim children had 76% higher no-DPT prevalence than Christian children. Children from the majority religion in each country tended to have lower no-DPT prevalence than the rest of the population except in Muslim-majority countries.

Interpretation

Analyses of gaps in coverage according to religion are relevant to renewing efforts to reach groups that are being left behind, with an important role in the reduction of zero-dose children.

Educational videos to address vaccine hesitancy in childhood immunization

Background

As one of the essential programs that have been developed for decades, childhood immunizations are mandatory to protect children from vaccine-preventable diseases. Despite its availability and accessibility, immunization coverage has not reached the intended goals. Vaccine hesitancy and COVID-19 pandemic may threaten immunization coverage in children. This study aimed to evaluate the tailored educational videos to reduce vaccine hesitancy and analyze the changes in childhood routine immunization status.

Methods

This was an interventional quasi-experimental study in three subdistricts of North Jakarta, Indonesia. Participants were allocated into educational videos exposures (intervention group, n = 116) or to the digital version of the maternal and child health handbook (control group, n = 104). We administered a pre- and post-intervention vaccine hesitancy survey using the Parent Attitudes about Childhood Vaccines (PACV) questionnaire with cut-off scores of 50.

Results

A total of 220 parents were recruited in this study from June 18, 2021, to December 10, 2021. The pre-intervention PACV survey showed that 19 (8.6%) parents were vaccine-hesitant from both groups: 12 (10.3%) and 7 (6.7%) of parents among intervention and control groups. After the interventions, there were 8 (6.9%) and 8 (7.7%) vaccine-hesitant parents in the intervention and control groups, respectively. We found a significant difference in the post-intervention PACV median score between the intervention and control groups (17 vs 23; p = 0.035). Around 25% of parents have not completed their children’s immunization status: 22.4% and 28.8% in the intervention and control groups, respectively. There was a significant difference between the proportion of PACV hesitancy on the immunization status within intervention and control groups (p = 0.001).

Conclusion

There was a reduction in vaccine hesitancy after interventions. Educational videos intervention distributed through WhatsApp group was associated with lower vaccine hesitancy and can be used as health education tools among Indonesian parents in the community.

Vaccine hesitancy among communities in ten countries in Asia, Africa, and South America during the COVID-19 pandemic

Vaccine hesitancy is considered one of the greatest threats to the ongoing coronavirus disease 2019 (COVID-19) vaccination programs. Lack of trust in vaccine benefits, along with concerns about side effects of the newly developed COVID-19 vaccine, might significantly contribute to COVID-19 vaccine hesitancy. The objective of this study was to determine the level of vaccine hesitancy among communities in particular their belief in vaccination benefits and perceived risks of new vaccines. An online cross-sectional study was conducted in 10 countries in Asia, Africa, and South America from February to May 2021. Seven items from the WHO SAGE Vaccine Hesitancy Scale were used to measure a construct of belief in vaccination benefit, and one item measured perceived riskiness of new vaccines. A logistic regression was used to determine which sociodemographic factors were associated with both vaccine hesitancy constructs. A total of 1,832 respondents were included in the final analysis of which 36.2% (range 5.6-52.2%) and 77.6% (range 38.3-91.2%) of them were classified as vaccine hesitant in terms of beliefs in vaccination benefits and concerns about new vaccines, respectively. Respondents from Pakistan had the highest vaccine hesitancy while those from Chile had the lowest. Being females, Muslim, having a non-healthcare-related job and not receiving a flu vaccination during the past 12 months were associated with poor beliefs of vaccination benefits. Those who were living in rural areas, Muslim, and those who did not received a flu vaccination during the past 12 months had relatively higher beliefs that new vaccines are riskier. High prevalence of vaccine hesitancy in some countries during the COVID-19 pandemic might hamper COVID-19 vaccination programs worldwide. Programs should be developed to promote vaccination in those sociodemographic groups with relatively high vaccine hesitancy.

Health Beliefs and Socioeconomic Determinants of COVID-19 Booster Vaccine Acceptance: An Indonesian Cross-Sectional Study

INTRODUCTION

The threat of new SARS-CoV-2 variants indicates the need to implement COVID-19 vaccine booster programs. The aim of this study was to identify the level of booster acceptance and its determinants.

METHODS

A cross-sectional online survey was conducted in Jakarta and Bali, Indonesia. Booster acceptance was divided into three categories: non-acceptor, planned acceptor, and actual acceptor. The primary independent variables were health beliefs, media influence, and trust in authoritative sources. Other covariates included demographics, socioeconomic status, and COVID-19 history. A primary analysis was conducted through multinomial logistic regression. The effects of the hypothetical situations on booster acceptance were tested using the Wilcoxon signed-rank test.

RESULTS

The final analysis included 2674 respondents with a booster acceptance rate of 56.3% (41.2% planned acceptors, 15.1% actual acceptors). Health beliefs, social media influence, and trust in authoritative information sources were identified as determinants for planned and actual booster acceptance. Socioeconomic status indicators were also identified as determinants for actual booster acceptance. Booster acceptance was increased in hypothetical scenarios involving booster requirements for work, travel, and accessing public places.

CONCLUSIONS

Booster acceptance was found to be lower than the predicted primary vaccine acceptance prior to its launch. The acceleration of booster coverage requires strategies that leverage health beliefs and focus on people with a lower socioeconomic status.

Parent's risk preference and childhood vaccination: evidence from Indonesia

A vaccines advisory group to the World Health Organization (WHO) identified complacency, inconvenience in accessing vaccines, and lack of confidence as key reasons for hesitancy. In childhood vaccination, the decision to take a vaccine relies on parents' decisions. Our study explored the relationship between parents' risk aversion and complete childhood vaccination status to identify whether demand contributes to vaccine hesitancy in Indonesia. We examined risk aversion using data from the fifth-wave Indonesian Family Life Survey (IFLS), focusing on parents with extreme risk aversion or fear of uncertainty. The logistic regression shows a negligible relationship between parents' risk aversion and childhood vaccination; nevertheless, parents who fear uncertainty tend to avoid vaccination. The results of this study encourage public health professionals and policymakers to properly design vaccine campaigns with careful consideration of the risk preference dimension of the targeted beneficiaries.

The determinants of SARS-CoV-2 vaccine hesitancy in a rural area of an Indonesia-Philippines border island: A mixed-method study

BACKGROUND

The SARS-CoV-2 vaccination program campaign has been underway in Indonesia for people aged ≥18 years. The program's success can be hampered by vaccine hesitancy in communities. This study aims to elucidate the determinants of SARS-CoV-2 vaccine hesitancy in a rural area of the Indonesia-Philippines border island Sangihe.

METHODS

A mixed-methods study was conducted; a quantitative part involving a cross-sectional survey was carried out among participantes aged ≥18 years to determine the prevalence and determinants of SARS-CoV-2 vaccine hesitancy. The qualitative part involved in-depth interviews to explore the perceptions towards the SARS-CoV-2 vaccine.

RESULT

Among 557 participantes, the prevalence of vaccine hesitancy was 63.9% (95% CI: 59.8-67.9). In the adjusted analysis, three factors affected vaccine hesitancy: education (aOR: 0.40; 95% CI: 0.22-0.70), knowledge of the SARS-CoV-2 vaccine (aOR: 2.17; 95% CI: 1.41-3.34) and willingness to pay (aOR: 0.12; 95% CI: 0.07-0.20). The majority of reasons for refusing the vaccine included doubt regarding its safety and effectiveness, the fear of side effects, lack of information regarding the vaccine and local Christians' religious beliefs.

CONCLUSION

This study found that most adults in the area were hesitant about the SARS-CoV-2 vaccine. Lack of knowledge, a low level of education and misinformation were factors that greatly affected vaccination hesitancy. The government, by involving religious leaders, is expected to pay serious attention to the dissemination of accurate and convincing information to the public regarding the safety and importance of the SARS-CoV-2 vaccine.

Sharia (Islamic Law) Perspectives of COVID-19 Vaccines

The Coronavirus disease 2019 (COVID-19) pandemic has caused health, economic, and social challenges globally. Under these circumstances, effective vaccines play a critical role in saving lives, improving population health, and facilitating economic recovery. In Muslim-majority countries, Islamic jurisprudence, which places great importance on sanctity and safety of human life and protection of livelihoods, may influence vaccine uptake. Efforts to protect humans, such as vaccines, are highly encouraged in Islam. However, concerns about vaccine products’ Halal (permissible to consume by Islamic law) status and potential harm can inhibit acceptance. Fatwa councils agree that vaccines are necessary in the context of our current pandemic; receiving a COVID-19 vaccination is actually a form of compliance with Sharia law. Broader use of animal component free reagents during manufacturing may further increase acceptance among Muslims. We herein explain the interplay between Sharia (Islamic law) and scientific considerations in addressing the challenge of COVID-19 vaccine acceptance, particularly in Muslim populations.

The Role of Sex, Ethnicity, Age, and Nutritional Status in the Seropositivity of the Measles Vaccine

AIM: This study investigates the relationship between sex, ethnicity, age, nutritional status with the seropositivity of the Edmonston-Zagreb vaccine in children. METHODS: A cross sectional, observational study was conducted. A total of 45 children were differentiated based on sex, ethnicity, age, and nutritional status when they received the Edmonston-Zagreb measle vaccine for the first time. Flow cytometry was used to look at differences in antibody status as well as populations of CD-4 and CD-8 cells that release IFN- γ. RESULTS: We found no significant differences in antibody levels or CD-4 and CD-8 cell populations that secrete IFN- γ between boys and girls (p > 0.05). Besides, similar results were also confirmed in comparisons between Javanese and Sundanese ethnic groups, 9 months versus more than 9 months of age, or normal versus low body mass index (p > 0.05). CONCLUSIONS: We conclude that sex, race, age, and nutritional status had no effect on immune response to vaccination. As a result, there was no barrier to seroconversion and optimal immunological performance in the children in this trial who received the Edmonston-Zagreb measles vaccination.

Effect of tailored information of vaccination schedule on vaccine uptake in northern Nigeria

Introduction: A vaccination schedule is complex and dynamic that requires repetitive and timely clinic visits by children and their caretakers. This study investigates whether providing caregivers with one-time tailored information on the vaccination schedule improves the vaccine uptake among children.Methods: The study participants were 534 women each with a child age 8 months or less; they were from 11 settlements in Jada, a local government area in Adamawa state, Nigeria. The study was conducted on September 2019 to June 2020. Women were randomly selected to be assigned to a treatment group to be provided with one-time tailored information on their children's current vaccination status and the next schedule for vaccination, while women in the control group were provided with generic information on the vaccination schedule. We employed the ordinary least squares (OLS) and logistic regression depending on the type of dependent variables to analyze the treatment effect.Results: After the women received tailored information on the vaccination schedule, the number of clinic visits for vaccination increased. However, the tailored information did not improve the vaccine uptake among children at a particular age nor the full vaccination rate.Conclusion: One-time tailored information has an immediate but no sustainable effect. It might be important for women to be constantly reminded about the vaccination schedule.

Disruption of childhood vaccination during the COVID-19 pandemic in Indonesia

The aim of this study was to assess the magnitude of childhood vaccination disruption and to determine the predictors of delaying childhood vaccinations during the coronavirus disease 2019 (COVID-19) pandemic among Indonesian parents. We conducted a nationwide, online, cross-sectional study. A set of questionnaires assessed the disruption of childhood vaccinations and possible explanatory variables, including demographic characteristics, current underlying disease, exposure to and confidence in COVID-19 information, perceived risk, attitude and practice on vaccination, and COVID-19 prevention practice. A multivariable linear regression was used to characterize the relationship between explanatory variables and delayed childhood vaccination. We included 1137 respondents for analysis, of which 52.6% were males and 58.4% participants aged between 31 and 50-years old. Disruption of childhood vaccination service in local health facilities was reported in 42.2% (480/1137) of respondents and 13.3% (193/1137) of respondents explained that their children could not be vaccinated because a healthcare facility temporary stopped the vaccination service. Of all respondents, 312 (27.4%) delayed vaccinating their children for a compulsory vaccination shot. Factors associated with higher odds of delaying compulsory vaccinations for children were employment and chronic disease status, flu vaccination status in the past year, and prior COVID-19 infection. In conclusion, there was a significant disruption of childhood vaccination practices in Indonesia during the COVID-19 pandemic. This is not only due to healthcare closures but also due to parents' practice - delaying the compulsory childhood vaccination for their children. We urge the government to strengthen strategies to ensure childhood vaccination services are available to all children in the country during a pandemic.
