Evaluation of Childhood Vaccine Refusal and Hesitancy Intentions in Turkey

Vaccine refusal in pregnant women in Kahramanmaraş: a community-based study from Türkiye

Background

The global health landscape is increasingly challenged by the rejection of childhood vaccines. This study investigates vaccination reservations and refusal among pregnant women.

Methods

A cross-sectional study was conducted in Kahramanmaraş, Türkiye, spanning January to March 2019, entailing face to face interviews with 938 pregnant women. The questionnaire collected sociodemographic data and probed vaccination attitudes. The decision to vaccinate the baby was treated as the dependent variable, analyzed alongside sociodemographic factors and other variables. Data underwent evaluation via descriptive analysis, the Chi-square test, and binary logistic regression.

Results

Participants had a mean age of 27.6 years. Among them 20 (2.1%) expressed intent to either abstain from or partially vaccinate their babies, with 70% citing apprehensions regarding potential vaccine-related harm. Statistical analysis unveiled that higher economic income, elevated parental education level, fewer than two children, reliance on the Internet for vaccination information, and a lack of trust in physicians significantly correlated with vaccine refusal among pregnant women (p < 0.05).

Conclusions

The study concludes that dissemination of vaccination information by the healthcare professionals, complemented by the enactment of pro-vaccine internet policies holds promise in shaping vaccination behavior.

The frequency and determinants of vaccine hesitancy among parents of preschool and kindergarten students in Edirne central district

PURPOSES

The aim of our study is to determine the frequency of vaccine hesitancy and the associated factors among parents with preschool children in a city center.

DESIGN AND METHODS

We conducted a cross-sectional study among parents of preschool children in the central district of Edirne. The cluster sampling method was applied. The data collection tools consisted of a questionnaire designed by the researchers and The Parent Attitudes about Childhood Vaccines (PACV) Scale. The correlations between vaccine hesitancy among parents factos such as the vaccine's content, adverse effects, religious beliefs, media coverage, reliance on community leaders, and the usage of complementary and alternative medical methods were examined.

RESULTS

The study group consisted of 315 individuals and the prevalence of vaccine hesitancy among participants was determined to be 13%. The mean PACV scale score of the parents was 29.76 ± 16.62. According to multivariate analyses, the odds ratios (%95 CI) of variables that were statistically significantly associated with parental vaccine hesitancy were as follows: being a mother 8.77 (1.02-75.07), vaccine side effects 2.91 (0.93-9.16), low/equal income level 6.80 (2.45-18.86), low/high income level 5.74 (1.65-20.0), religious reasons 3.33 (1.34-8.25), and media influence 9.53 (3.75-24.18).

CONCLUSION

Overall, vaccine hesitancy was observed at one in every 7 parents in the central district of Edirne province, and the main determinants of hesitancy were low-income status, media influence and religious beliefs, advers effects and being mother. Community-based intervention programs should be established to combat vaccine hesitancy.

PRACTICAL IMPLICATIONS

The PACV scale is recommended for detecting community-based vaccine hesitancy.

Childhood Vaccine Attitude and Refusal among Turkish Parents

We aimed to understand and resolve anti-vaccine attitudes by examining the factors associated with vaccine attitudes and exploring potential strategies to improve childhood vaccination rates. Between 2014 and 2021, a total of 628 families refused vaccination in Adiyaman. A total of 300 families accepted visits and were visited. During the visits, the families were administered a questionnaire to determine the reasons for vaccine rejection and their opinions on the matter. While providing general information about the vaccine, parents were encouraged to reconsider their decision, and at the end, parents completed the questionnaire. The questionnaire included sociodemographic questions, reasons for vaccine refusal, and a vaccine attitude scale. Among the participants in the study, 9.3% were convinced about the vaccine. The mean vaccine attitude scale score was calculated as 23.6 ± 2.5 (min = 15-max = 29). Significantly higher rates of persuasion were observed among fathers (17.3%) compared to mothers (7.7%) (p = 0.038). Participants who had received some vaccinations had a higher rate of persuasion (11.6%) compared to those who had not received any vaccinations (2.6%) (p = 0.02). Childhood vaccine refusal is a complex issue that has been the subject of numerous studies. Studies on this subject will increase awareness of vaccines.

Rates of childhood vaccine refusal in Turkey during 2016-2017: Regional causes and solutions

OBJECTIVE

Vaccine hesitancy is a growing problem globally. This study aimed to detect the rates of vaccine refusal (VR) during childhood in each province and region of Turkey from 2016 to 2017 and to evaluate the experiences of Expanded Programme on Immunization (EPI) managers regarding childhood VR and opinions to solve and reduce vaccine hesitancy in Turkey.

METHODS

VR was defined as the refusal to vaccinate for at least one vaccine in children aged 0-23 months. In this descriptive study, information on notified VR cases and recommended solutions from every province in Turkey was accessed by the local EPI manager for the period 2016-2017. The VR rates were calculated.

RESULTS

From 80 provinces, 8977 VR cases were detected in 2016 (VR rate 3.5‰) and 14,779 cases in 2017 (VR rate 5.9‰; p<0.001). One quarter of Family Health Units reported at least one case of VR. The highest VR rate in children aged under 2 years was in East Marmara (8.4‰) in 2016, and the West Anatolia Region (10.9‰) and East Marmara region (10.9‰) in 2017. Concerns about the vaccine content, harmfulness, and fears about adverse effects were the most common reasons underlying VR. Educating healthcare workers about vaccines and interpersonal communication skills, increasing patient information with informative brochures, and preventing anti-vaccination publications in the media were the most frequent recommendations to solve VR.

CONCLUSIONS

In Turkey, VR cases continue to increase. Correct and adequate information, effective communication, and trust between healthcare workers and parents can help reduce VR.

Vaccine hesitancy from the parent perspectives: protocol for a qualitative study in Iran

INTRODUCTION

WHO declared vaccine hesitancy as a global public health threat in 2019. Since even a slight reduction in vaccine coverage rates can lead to a decrease in herd immunity, it is imperative to explore the underlying factors affecting vaccine hesitancy. This qualitative study protocol aims to explore determinant factors that influence vaccine hesitancy in Iran from the parent's perspective.

METHODS AND ANALYSIS

Descriptive-Interpretive Qualitative research will be conducted to gain an insight into vaccine hesitancy in the west of Tehran province in Iran. Participants in the study will be recruited from vaccine-hesitant parents of children under 5 years' old who will be recognised as being hesitant to extract from the national health information system. The semistructured interviews and in-depth questions will be performed both face-to-face in an open space such as a park near their homes and via video call because of the COVID-19 pandemic and social distancing. Interviews will be conducted by a trained qualitative person. Transcribed data will be analysed through thematic analysis.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the research ethics committee at the Iran University of Medical Sciences (Approval ID #IR.IUMS.REC.1399.273). The results of the study are expected to be presented by the end of 2022 year. A variety of dissemination methods will be employed to communicate research findings, including presentations at conferences and peer-reviewed publications.

Knowledge, attitudes and behaviors of Inonu University faculty members regarding childhood vaccine refusal

INTRODUCTION

Although there is a lot of scientific evidence that the benefits of vaccines outweigh their risks, hesitancy about the safety of vaccines can occur in every segment of the community. In this study, we aimed to determine the knowledge, attitudes, and associated factors of vaccine hesitancy among Inonu University faculty members regarding childhood vaccinations.

METHOD

This is a cross-sectional study, and 258 faculty members were included in the study. The questionnaire used in the study explored the sociodemographic characteristics of the faculty members and their knowledge, attitudes and behaviors regarding childhood vaccination. A chi-square test and a fisher exact test were used for statistical analysis.

RESULTS

Of the faculty members, 31.8% were hesitant about childhood vaccines, 51.9% stated that there were studies reporting the side effects of vaccines, 48.1% did not agree with giving booster doses of vaccines, 35.7% stated that vaccines could cause autism due to the chemicals contained in the vaccines. The most important information sources of university faculty regarding childhood vaccines members are scientific publications and health professionals.

CONCLUSIONS

Faculty members level of hesitancy about vaccines was high and since health professionals and scientific articles are the most important information sources of faculty members, misinformation here may affect their knowledge, attitudes and behaviors about vaccination.

Factors associated with pediatric vaccine hesitancy of parents: a cross-sectional study in Turkey

Aim: This study aims to determine the prevalence and associated factors of vaccine hesitancy in females with children aged 12 months to 6 years who receive service from the antenatal class of a tertiary hospital in Turkey.Method: The study group includes 370 parents receiving service from a tertiary hospital. The data collection tools of the study were a descriptive data form and the Parent Attitudes about Childhood Vaccines survey.The data were analyzed using chi-square analysis and logistic regression analysis.Results: In our study, the prevalence of vaccine hesitancy was determined as 13.8% and vaccine refusal prevalence as 4.8%. In univariate analysis, vaccine hesitancy was found to be significantly higher in mothers with a university education, who got pregnant with treatment, who were not trained about pediatric vaccines in the antenatal follow-up, who followed anti-vaccine groups on social media, and who did not use vitamin D and iron supplements regularly or never used for their child. Vaccine hesitancy was significantly higher in parents who stated that their information sources of vaccines were not scientific, who were worried about vaccine ingredients (aluminum, mercury, pig gelatine) and who used alternative medicine practices (p < .05). In multivariate analysis, the risk of vaccine hesitancy increases 3.05 times in pregnancies with treatment, 3.74 times in those who did not use vitamin D or iron preparations, 3.01 times in those who followed anti-vaccine groups on social media,2.93 times in parents who were worried about the vaccine ingredients.Conclusion: Our findings suggest that the prevalence of vaccine hesitancy and risk factors should be monitored closely in the following years.

Investigation of knowledge, attitude and behaviours of parents refusing childhood vaccines in Malatya, an eastern city of Turkey

OBJECTIVES

The modern rise of vaccine rejection in society can alter the current progress that has been made towards the control and prevention of certain diseases, possibly even resulting in epidemics involving these preventable diseases. The aim of this study is to analyse the knowledge, attitude and behaviours of parents in Malatya city who rejected childhood vaccines.

METHODS

This descriptive, cross-sectional study was conducted between September-November 2019. The study includes parents who rejected vaccines and are registered in the family medicine clinics of Malatya city - total of 453 participants. The objective was to include all parents and avoid a sampling procedure. However, only 151 (33%) parents agreed to participate. These parents who rejected vaccines were individually contacted by phone. Descriptive data was represented by number (n) and percentage (%). The chi-square test was utilized in the statistical analysis of data and p < 0.05 was considered significant in all evaluations.

RESULTS

Mothers in the study group had a mean age of 26.07 ± 3.64, while the fathers were on average 30.03 ± 4.59 years of age; 98% of parents were aware of the health risks that vaccine rejection presented; 93% of parents were not satisfied with the explanation, insight, and advice that the healthcare personnel provided regarding vaccines. All parents of the study group stated the following: vaccines should not be administered because other children in their close environment acquired a disease as a result of vaccination, vaccines can harm the immune system of children - not yet fully developed, vaccines are unsafe and endanger the health of children.

CONCLUSIONS

It can be said that parents who have obtained a lot of false information possess altered decisions and views on vaccinations, to the point where they accept the risks presented by preventable diseases. In addition, individuals lose trust following negative experiences with vaccination.

Knowledge and behaviors of nurses working at Inonu University Turgut Ozal Medical Center on childhood vaccine refusal

Among 10 global problems of 2019 determined by the World Health Organization, vaccine refusal was one of the problems mentioned. In this context, health services and health personnel whose main objectives are to keep individuals healthy and to prevent diseases have major responsibilities. This study aims to analyze knowledge and behavior of nurses working at Inonu University Turgut Ozal Medical Center on childhood vaccine refusal.This study, conducted between June and July 2019, is a descriptive cross-sectional study. It was conducted in a hospital located in Malatya in eastern Turkey. At the time of the study, 850 nurses work in this hospital. Sample size was calculated to be 263 at a confidence interval of 95% and strength of 80%. Chi-square test and Fisher's exact test were used in statistical analyses.In the present study, 31.7% of the participating nurses stated that they had concerns about childhood vaccines. Two-thirds of nurses stated that their knowledge on vaccines was from their education. The level of hesitance in those agreeing to the fact that vaccines caused autism and infertility, those stating that they did not trust vaccine-producing companies, and those stating that catching the disease was a better immunization method than vaccination was significantly higher than those not agreeing to these and those who were indecisive (p < .05).One-third of nurses was proven to have hesitance on childhood vaccines, and this rate is rather high. Nurses, being both health personnel and the communication channel for guiding parents, should be provided necessary training and practices in order to ease their hesitance on vaccination.

I'm a mother, therefore I question": Parents' legitimation sources of and hesitancy towards early childhood vaccination

This study was conducted with mothers living in Ankara and registered in the year 2019 with the Immunization Services Unit of the Provincial Directorate of Health as cases of vaccine refusal. This qualitative study used semi-structured interviews to understand how mothers decide about child vaccination and the attitudes, perceptions, and beliefs underlying these decisions. A total of 23 interviews were conducted by two of the authors between March and September 2019. Each of the 23 participants had at least one child aged five years or younger and were living in Ankara. The study shows that mothers with vaccine hesitancy constitute a heterogeneous group whose members have differing levels of hesitation and concern about the vaccination of their children. It is also observed that the most important factor that affects their decisions is related to trust.

The effects of the COVID 19 pandemic on vaccine decisions in pregnant women

Background

Pregnancy is an important time for developing attitudes and beliefs about childhood vaccinations. Vaccinations are among the most effective way of preventing some infectious diseases. Discussions on vaccinations have increased due to the Covid-19 pandemic and there is an opportunity to give society correct information on vaccinations.

Aim

The aim of the study was to determine the opinions of pregnant women on vaccinations in pregnancy and childhood and the effect of the Covid-19 pandemic on these views.

Methods

The study was conducted as a cross-sectional study. The sample included 152 pregnant women. Data were collected through a 25-item online questionnaire created by the researchers.

Results

It was found in our study that 29.6% of pregnant women using forum websites exhibited hesitant attitudes towards vaccinations. The vaccine hesitancy rate was found to be high in pregnant women who said that their economic level was low and who worried about the risks of vaccination. The Covid-19 pandemic was reported to be the cause of a decrease in vaccine hesitancy in 28.9% of the participants.

Conclusion

The events surrounding the pandemic provided an opportunity to explain how pregnant women feel about vaccinations. Providing pregnant women with access to correct information from health workers may reduce the problem of trust, which is among the most important reasons for vaccine hesitancy.

Vaccine mistrust among family healthcare professionals and vaccine hesitancy in the communities they serve in Turkey in 2019: a cross-sectional study

AIM

This study aims to determine the causes of vaccine mistrust among family healthcare professionals (FHP) in the unit where they serve and vaccine hesitancy of families.

METHOD

The study group consisted of 682 FHPs working in a primary health care institution. The data collection tools of the study included a sociodemographic data form and a vaccine hesitancy data form. Pearson's chi-square analysis and logistic regression analysis were performed to analyze the data.

FINDINGS

To the question of "Do you trust the active ingredient in the vaccines?", only 2.1% of FHPs responded "I do not trust" and 18.9% answered "I am indecisive". 70.7% of FHPs said that at least one vaccine hesitant family was in the unit where they served. The most important reasons stated by FHPs on behalf of such families were vaccine mistrust (73.2%), the belief that they may be harmful for the child (58.7%), and the belief that vaccines cause autism (55.6%). In the univariate analysis, vaccine mistrust was significantly higher in FHPs who were measles-hesitant and responded "The decision to get vaccinated or not should belong to the family voluntarily". From logistic regression analysis, vaccine mistrust in FHPs increased 2.8-fold for those who did not think vaccination should be compulsory, 2.7-fold for those who did not think that vaccination refusal should be legally enforced, and 1.61-fold for those under age 35 years.

CONCLUSION

It was observed that FHPs had high sensitivity and positive attitudes toward vaccination in general.

Parental Opinions and Approaches about Childhood Vaccinations: Are Anti-vaccination Approaches and Indecisiveness Parental Rights?

This study aimed to analyze parental opinions regarding immunization services and the factors that affect parental decisions regarding the vaccination of their children. We conducted descriptive study with 373 parents. The Parent Information Form and the Public Attitude Toward Vaccination Scale-Health Belief Model developed to evaluate vaccination approaches, were used. Of the parents who participated in the study, 35.9% stated that they found the information on childhood vaccinations unreliable or that they doubted the credibility of the information. In addition, most of the parents (71%) stated that they believed that the high number of immigrant children in the country causes contagious diseases to increase. It is found that there are statistically significant higher scores in the subscales of severity, susceptibility, and health motivation among the parents who disagree with the media statements on anti-vaccination attitudes (p < 0,001). Opinions and approaches of parents toward childhood vaccinations are affected by sociodemographic characteristics. In this study, the educational level of parents was found to be the most important variable affecting the approach of parents toward vaccinations.

Unvaccinated children as community parasites in National Qualitative Study from Turkey

Background

This national qualitative study explores (1) the experiences, observations, and opinions of health care workers (HCWs) about beliefs, socioeconomic, cultural, and environmental characteristics of parents refusing vaccination and (2) regional differences in the identified risk factors; (3) recommended solutions to improve vaccine acceptance in each of 12 regions in Turkey.

Methods

In total, we carried out 14 individual semi-structured in-depth interviews and 10 focus group discussions with 163 HCWs from 36 provinces. A thematic analysis was performed to explore HCWs’ observations about the parents’ decisions to reject vaccination and possible solutions for vaccine advocacy.

Results

Within the analyzed data framework, vaccine refusal statements could be defined as vaccine safety, the necessity of vaccines, assumptions of freedom of choice, health workers’ vaccine hesitancy, lack of information about national vaccination schedule and components, not trusting the health system, anti-vaccine publications in social media and newspapers, and refugees. Suggestions based on the HCWs suggestions can be summarized as interventions including (1) creating visual cards with scientific data on vaccine content and disease prevention and using them in counseling patients, (2) writing the vaccine components in a way understandable to ordinary people, (3) highlighting the national quality control and production in the vaccine box and labels, (4) conducting interviews with community opinion leaders, (5) training anti-vaccine HCWs with insufficient scientific knowledge and (6) reducing the tax of parents whose children are fully and punctually vaccinated.

Conclusions

The solution to vaccine rejection begins with the right approaches to vaccination during pregnancy. Prepared written and visual information notes should present the information as “vaccination acceptance” rather than “vaccination refusal”. Further studies on vaccine refusal rates should be carried out in various regions of the world so that region-specific actions are implemented to decrease the anti-vaxxer movement and to prevent an outbreak of infectious diseases.
