Parents' Perspectives about Vaccine Hesitancies and Vaccine Rejection, in the West of Turkey

Analysis of Differences in User Groups and Post Sentiment of COVID-19 Vaccine Hesitators in Chinese Social-Media Platforms

(1) Background: The COVID-19 epidemic is still global and no specific drug has been developed for COVID-19. Vaccination can both prevent infection and limit the spread of the epidemic. Eliminating hesitation to the COVID-19 vaccine and achieving early herd immunity is a common goal for all countries. However, efforts in this area have not been significant and there is still a long way to go to eliminate vaccine hesitancy. (2) Objective: This study aimed to uncover differences in the characteristics and sentiments of COVID-19 vaccine hesitators on Chinese social-media platforms and to achieve a classification of vaccine-hesitant groups. (3) Methods: COVID-19-vaccine-hesitation posts and user characteristics were collected on the Sina Microblog platform for posting times spanning one year, and posts were identified for hesitation types. Logistic regression was used to conduct user-group analysis. The differences in user characteristics between the various types of COVID-19 vaccine posts were analysed according to four user characteristics: gender, address type, degree of personal-information disclosure, and whether they followed health topics. Sentiment analysis was conducted using sentiment analysis tools to calculate the sentiment scores and sentiment polarity of various COVID-19 vaccine posts, and the K-W test was used to uncover the sentiment differences between various types of COVID-19-vaccine-hesitation posts. (4) Results: There are differences in the types of COVID-19-vaccine-hesitation posts posted by users with different characteristics, and different types of COVID-19-vaccine-hesitation posts differ in terms of sentiment. Differences in user attributes and user behaviors are found across the different COVID-19-vaccine-hesitation types. Ultimately, two COVID-19-vaccine-hesitant user groups were identified: Body-related and Non-bodily-related. Users who posted body-related vaccine-hesitation posts are more often female, disclose more personal information and follow health topics on social-media platforms. Users who posted non-bodily-related posts are more often male, disclose less personal information, and do not follow health topics. The average sentiment score for all COVID-19-vaccine-hesitant-type posts is less than 0.45, with negative-sentiment posts outweighing positive- and neutral-sentiment posts in each type, among which the "Individual rights" type is the most negative. (5) Conclusions: This paper complements the application of user groups in the field of vaccine hesitation, and the results of the analysis of group characteristics and post sentiment can help to provide an in-depth and comprehensive analysis of the concerns and needs of COVID-19 vaccine hesitators. This will help public-health agencies to implement more targeted strategies to eliminate vaccine hesitancy and improve their work related to the COVID-19 vaccine, with far-reaching implications for COVID-19-vaccine promotion and vaccination.

Childhood vaccine hesitancy in two regions with different socioeconomic backgrounds in Turkey

Aim

This study investigated childhood vaccine hesitancy in two regions with different socioeconomic backgrounds in Kayseri, Turkey.

Subject and methods

The study population consisted of all people over 18 years of age admitted to two family health centers (No 65 and 103) in a city center for any reason.

Results

Participants living in the high socioeconomic status (SES) region had a significantly lower mean rating on the CVHQ (Childhood Vaccine Hesitancy Questionnaire - see below) than those living in the low SES region.

Conclusion

Vaccine hesitancy is the main reason for vaccine refusal. Therefore, authorities should provide adequate and accurate information about the significance of vaccines to raise public awareness.

Changes in parents' attitudes towards childhood vaccines during COVID-19 pandemic

BACKGROUND

Concerns about the safety and adverse reactions of rapidly-developed vaccines against COVID-19 contributed to parents' vaccine hesitancy and this situation created an opportunity for anti-vaccine campaigners. The aim of this study was to examine the changes in parents' attitudes towards childhood vaccines during COVID-19 pandemic.

METHODS

In this cross-sectional study, parents of children who applied to the outpatient clinic of pediatric department of Trakya University Hospital, Edirne, Türkiye, between August 2020 and February 2021 were recruited into two study groups according to COVID-19 peak time in Türkiye. Group 1 included parents of children who applied after first peak of the COVID-19 pandemic and Group 2 included parents of children who applied after second peak. The World Health Organization 10-item Vaccine Hesitancy Scale (WHO-VHS) was applied to each group.

RESULTS

A total of 610 parents agreed to participate in the study. Group 1 and 2 consisted of 160 and 450 parents, respectively. While the number of parents who were hesitant about childhood vaccines was 17 (10.6%) in Group 1, it was 90 (20%) in Group 2. A statistically significant difference was found between the two groups (p = 0.008). The (WHO-VHS) mean ± SD score was found to be higher in Group 2 (23.7 ± 6.9) than Group 1 (21.3 ± 7.3) (p < 0.001). The WHO-VHS- mean ± SD scores of parents who experienced COVID-19 infection themselves or their family or acquaintances were significantly lower than those who did not (20.0 ± 6.5 vs. 24.7 ± 6.9) (p < 0.001).

CONCLUSIONS

The hesitant attitudes towards childhood and COVID-19 vaccines were low in parents who directly or indirectly experienced COVID-19 or were worried about the devastating effects of this disease. However, it was shown that as the COVID-19 pandemic progressed, parents' hesitations towards childhood vaccines increased.

What Motivates People to Receive Continuous COVID-19 Vaccine Booster Shots? An Expectation Confirmation Theory Perspective

(1) Background: Abundant evidence has shown that the COVID-19 vaccine booster is highly effective against the Omicron variant. It is of great practical significance to explore the factors influencing the intention to receive COVID-19 booster shots. (2) Methods: We introduced expectation confirmation theory as the basis to construct a model of the factors of the vaccination intention for COVID-19 vaccine boosters. We obtained two batches of questionnaires through Chinese social platforms, with a valid sample size of 572. To test the model, we used SmartPLS3.0 software for empirical analysis. (3) Results: In terms of the characteristics of the vaccine itself, perceived vaccine efficacy and perceived vaccine safety had significant positive effects on expectation confirmation. Regarding vaccination services, perceived vaccination convenience also had a significant positive effect on expectation confirmation. Expectation confirmation positively affected the vaccination intention for the COVID-19 vaccine boosters. Furthermore, the results showed two moderating effects: first, health consciousness negatively moderated the positive effect of perceived vaccine safety on expectation confirmation; second, the time interval since the last dose negatively moderated the positive effect of perceived vaccine efficacy on expectation confirmation. (4) Conclusions: Our research demonstrated that there is an expectation confirmation process for previous COVID-19 vaccines before people consider whether to obtain a booster shot. Perceived vaccine efficacy and perceived vaccine safety remained important factors in receiving COVID-19 booster shots, and our conclusions were consistent with previous literature. In this study, multiple dimensions such as distance and cost were used to measure perceived vaccination convenience. This new variable improve the explanatory power of the convenience of the vaccination service and enrich the variables of the factor model of vaccination intention. In addition, the moderating effects of health consciousness and time interval were found. The findings can provide a theoretical reference for public health institutions to help them understand the formation process of people's intention to receive the COVID-19 vaccine booster.

A systematic literature review to clarify the concept of vaccine hesitancy

Vaccine hesitancy (VH) is considered a top-10 global health threat. The concept of VH has been described and applied inconsistently. This systematic review aims to clarify VH by analysing how it is operationalized. We searched PubMed, Embase and PsycINFO databases on 14 January 2022. We selected 422 studies containing operationalizations of VH for inclusion. One limitation is that studies of lower quality were not excluded. Our qualitative analysis reveals that VH is conceptualized as involving (1) cognitions or affect, (2) behaviour and (3) decision making. A wide variety of methods have been used to measure VH. Our findings indicate the varied and confusing use of the term VH, leading to an impracticable concept. We propose that VH should be defined as a state of indecisiveness regarding a vaccination decision.

Parental vaccine hesitancy and concerns regarding the COVID-19 virus

PURPOSE

This study assessed parental vaccine hesitancy in a metropolitan area of the United States. The study aimed to determine what characteristics and contributing factors influenced parental vaccine hesitancy and concerns regarding COVID-19.

DESIGN AND METHODS

An online survey was used to recruit 93 parents to answer demographic and vaccine hesitancy information. Vaccine hesitancy was measured using the Parent Attitudes about Childhood Vaccines survey. The study was conducted between June 2020 and September 2020 during the COVID-19 pandemic.

RESULTS

The rate of vaccine hesitancy was 15%. One hundred percent of vaccine hesitant parents were mothers, at least 30 years of age, married, and had completed at least some college. When characteristics of vaccine hesitant parents were compared to non-hesitant parents, the hesitant parents reported having more children, with 93% reporting two or more children compared to only 74% of non-hesitant parents (p = 0.046). Fifty percent of hesitant parents reported no concerns regarding COVID-19 compared to only 20% of non-hesitant parents (p = 0.006), and significantly less hesitant parents reported willingness to have their children receive a safe, effective COVID-19 vaccine if it were available compared to non-hesitant parents (p < 0.001).

CONCLUSIONS

Our findings indicate that older mothers with two or more children are more likely to be vaccine hesitant and this hesitancy extends to the current COVID-19 pandemic.

PRACTICE IMPLICATIONS

Healthcare providers can use the results of this study to identify parents at risk for vaccine hesitancy and initiate individualized education to promote on-time childhood vaccination.

Sleep disturbance and psychological distress among hospitalized children in India: Parental perceptions on pediatric inpatient experiences

PURPOSE

Investigate parental perceptions of children's sleep disturbance and psychological distress associated with an inpatient stay in a low-resource hospital setting.

DESIGN AND METHODS

Demographic and validated survey instruments were adapted for administration to parents of children in the medical wards of a tertiary hospital in India. Parents proficient in English, Hindi, Tamil, or Telugu with a child age 4-12 years admitted for at least 48 h were eligible to participate. All respondents completed the Factors Affecting Sleep Disturbance Scale, Sleep Duration Questionnaire, Sleep Disturbance Scale, and Kessler Psychological Distress Scale. Data analysis entailed descriptive statistics, correlations, and multivariate regressions to analyze relationships across responses on demographics, sleep disturbance, and psychological distress.

RESULTS

Among 105 parents with hospitalized children, most had children 4-6 years old (54%), including 65% boys and 35% girls. Parents reported that their children slept overnight in the hospital for a mean of 8.3 ± 1.6 h. Children 4-6 year old (relative risk ratio [RRR] = 0.63, p = .004), dyspnea (RRR = 8.73, p = .04), previous hospitalization (RRR = 9.17, p = .03), nighttime procedures (RRR = 2.97, p = .03, and missing home (RRR = 6.78, p < .001) were the factors affecting sleep. Factors affecting psychological distress was nighttime medication administration (RRR = 4.92, p = .01). Sleep disturbances correlated with psychological distress (r = 0.56; p < .01).

CONCLUSION

Sleep disturbance and associated psychological distress in hospitalized children were widely reported by parents queried in this low-resource hospital setting.

PRACTICAL IMPLICATIONS

Nurses can lead efforts in ameliorating sleep in hospitalized children, including partnering with stakeholders on measures to reduce sleep disruption. Child-centered interventions may improve sleep hygiene and decrease psychological distress among children.

Adaptation and validation of the Turkish version of the vaccine hesitancy 5 point Likert Scale

The decrease in vaccine acceptance has been recognized as an emerging public health problem and there is therefore a need for reliable and validated tools that identify vaccine hesitancy. The objective of this study was to adapt and validate the Turkish version of the Vaccine Hesitancy 5-point Likert Scale which was originally developed by the WHO Strategic Advisory Group of Experts on Immunization. The study was carried out in a Family Health Center (FHC) in Istanbul over the period June 1-November 30, 2020. The participants were parents who had applied to the FHC for well-child visits and had a child ≤18 months of age. After the process of translation and back-translation, the Turkish version was pilot-tested, and its test-retest reliability was evaluated among 40 parents at a two-week interval. The validation was carried out with 306 parents through exploratory factor analysis. There was no statistical difference between the test-retest scores (p = .17). The intraclass correlation coefficient was 0.98 (p < .001). Cronbach's alpha coefficient was 0.81. Factor analysis yielded two subscales that were named "confidence' and 'risk perception" and explained 63% of total variance. Our results suggest that the Turkish version of the Vaccine Hesitancy 5-point Likert Scale is a reliable and valid instrument.

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.

Exploring and Monitoring the Reasons for Hesitation with COVID-19 Vaccine Based on Social-Platform Text and Classification Algorithms

(1) Background: The COVID-19 pandemic is globally rampant, and it is the common goal of all countries to eliminate hesitation in taking the COVID-19 vaccine and achieve herd immunity as soon as possible. However, people are generally more hesitant about the COVID-19 vaccine than about other conventional vaccines, and exploring the specific reasons for hesitation with the COVID-19 vaccine is crucial. (2) Methods: this paper selected text data from a social platform to conduct qualitative analysis of the text to structure COVID-19 vaccine hesitancy reasons, and then conducted semiautomatic quantitative content analysis of the text through a supervised machine-learning method to classify them. (3) Results: on the basis of a large number of studies and news reports on vaccine hesitancy, we structured 12 types of the COVID-19 vaccine hesitancy reasons. Then, in the experiment, we conducted comparative analysis of three classifiers: support vector machine (SVM), logistic regression (LR), and naive Bayes classifier (NBC). Results show that the SVM classification model with TF-IDF and SMOTE had the best performance. (4) Conclusions: our study structured 12 types of COVID-19 vaccine hesitancy reasons through qualitative analysis, filling in the gaps of previous studies. At the same time, this work provides public health institutions with a monitoring tool to support efforts to mitigate and eliminate COVID-19 vaccine hesitancy.

Scared, powerless, insulted and embarrassed: hesitancy towards vaccines among caregivers in Cavite Province, the Philippines

BACKGROUND

Several studies have highlighted that vaccine hesitancy (VH) is among the most important threats to global health, especially in low- and middle-income countries, including the Philippines. However, there is a dearth of literature exploring family experiences of-or concerns related to-childhood vaccinations that gives voice to vaccine hesitant caregivers (VHCs) of small children. Here, we present insights from VHCs from the Philippines.

METHODS

This research draws on in-depth interviews (IDIs) with 44 VHCs who had previously delayed or refused vaccination for their children in rural and urban communities in Cavite Province, the Philippines. Amid the COVID-19 pandemic, we conducted IDIs via an online platform of the respondents' choosing (ie, Facebook messenger call, Skype and Zoom). All interviews were recorded, transcribed, translated and analysed drawing from the tenets of constructivist grounded theory. We use the social ecological model to structure our results.

RESULTS

Among the reasons for delay or refusal of childhood vaccinations, a fear of side effects emerged as the most salient concern, exacerbated by previous negative experiences (including trauma) from a dengue vaccine controversy in 2017. Respondents cited the dengue vaccine controversy as they expressed reluctance (regarding any new vaccines) and suspicion (towards school-based vaccination, the distribution channel used for the dengue vaccine). Heads of households opposing vaccines, perceptions that vaccines are non-essential and influences from the social and traditional media or neighbours contributed to further refusal and delay. Upon probing, VHCs recounted health system concerns particularly with regards to healthcare workers who are sometimes unable to answer their questions and can be dismissive or disrespectful regarding caregivers' concerns.

CONCLUSION

Understanding VH from the lens of VHCs highlights pathways for interventions to regain trust and bolster confidence towards vaccines. Our findings may serve as linchpins in the development of VH interventions aiming at changing behaviour on a population scale.

Determinants of parental hesitancy to vaccinate their children against COVID-19 in China

Vaccine hesitancy seriously hinders herd immunity. We explored the determinants of parental hesitancy to vaccinate children against Coronavirus Disease 2019 (COVID-19) in China.A population-based self-administered online questionnaire evaluating parental hesitancy in vaccinating their children against COVID-19 was conducted in Taizhou, China. Of the 2463 parents who received the invitation, 1788 (72.6%) responded to the survey.Of the repondents, 52.5% were hesitant. Mothers exhibited a greater proportion of vaccine hesitancy than fathers did (57.5% vs. 41.7%, P < 0.001). Multiple logistic regression analysis indicated that parents with children under 18 years of age (OR = 0.94, 95%CI: 0.90-0.99), lower knowledge scores about COVID-19 vaccination (Q1: OR = 1.92, 95%CI: 1.37-2.69; Q2: OR = 1.51, 95%CI: 1.10-2.08), lower awareness of the permission of vaccinating children (OR = 1.74, 95%CI: 1.36-2.23) and hesitancy to inoculate themselves (OR = 8.18, 95%CI: 6.48-10.33) were associated with parental hesitancy to inoculate their children. Results also revealed the disparity between fathers and mothers regarding associated factors.This study found that a substantial proportion of parents reported being hesitant to vaccinate children against COVID-19, implying the necessity of comprehensive assessment and health education programs for vaccination systems in China.
