Abstract
This study investigated the influences of mother-daughter communication and social media on mothers' HPV vaccine refusal for their daughters aged 9-17. A cross-sectional online survey among 11,728 mothers of girls aged 9-17 in Shenzhen, China was implemented between July and October 2023. Multi-level logistic regression models were fitted. Among 11,728 participants, 43.2% refused to have their daughters receive an HPV vaccination. In multivariate analysis, more openness in the mother-daughter communication (AOR: 0.99, 95%CI: 0.98, 0.99), perceived more positive outcomes of mother-daughter communication (AOR: 0.77, 95%CI: 0.75, 0.79), higher frequency of exposure to testimonials about daughters' HPV vaccination (AOR: 0.81, 95%CI: 0.78, 0.85) and information encouraging parents to vaccinate their daughters against HPV on social media (AOR: 0.76, 95%CI: 0.73, 0.79), and thoughtful consideration of the veracity of the information specific to HPV vaccines (AOR: 0.80, 95%CI: 0.77, 0.83) were associated with lower vaccine refusal. Mothers who were not the main decision-makers of daughters' HPV vaccination (AOR: 1.28 to 1.46), negative outcome expectancies of mother-daughter communication (AOR: 1.06, 95%CI: 1.04, 1.08), and mothers' HPV vaccine refusal (AOR: 2.81, 95%CI: 2.58, 3.06) were associated with higher vaccine refusal for their daughters. The level of mothers' HPV vaccine refusal for their daughters was high in China. Openness and outcome expectancies of mother-daughter communication and information exposure on social media were considered key determinants of HPV vaccine refusal for daughters. Future HPV vaccination programs should consider these interpersonal factors.

Abstract
Background China started to implement the HPV vaccination program for females in 2016. This study investigated associations between mothers' decisional conflicts, satisfaction with governmental health promotion materials, and their daughters' HPV vaccination uptake. Methods A cross-sectional online survey was conducted between July and October 2023 among mothers of girls aged 9-17 years in Shenzhen, China. Participants were mothers having a daughter aged 9-17 years at the survey date and a smartphone with internet access. About 3 % of all primary and secondary schools in Shenzhen were randomly selected by the research team (11 primary schools and 13 secondary schools). Teachers at the selected schools invited mothers of female students aged 9-17 years to complete an anonymous online questionnaire. Multivariate logistic regression was fitted. Results Among 11,728 mothers who completed the survey, 18.9% of their index daughters received at least one dose of HPV vaccination. In multivariate analysis, less decisional conflict about the choice of HPV vaccines for their daughters (AOR: 1.07, 95%CI: 1.05, 1.10), more satisfaction with the government's health promotional materials related to HPV vaccines (AOR: 1.15, 95%CI: 1.12, 1.19), receiving more cue to action from significant others (AOR: 1.23, 95%CI: 1.19, 1.27), and perceived higher self-efficacy related to HPV vaccines (AOR: 1.79, 95%CI: 1.67, 1.92) were associated with a higher uptake of HPV vaccines. Perceived susceptibility to HPV (AOR: 0.79, 95%CI: 0.74, 0.85), perceived barriers to having the index daughter receive HPV vaccines (AOR: 0.82, 95%CI: 0.80, 0.84), and mothers who were hesitant to receive HPV vaccination (AOR: 0.75, 95%CI: 0.68, 0.84) were associated with a lower uptake. Conclusion HPV vaccination uptake was low among girls in China. Future health promotion should address mothers' decisional conflicts about the choice of HPV vaccines for their daughters and improve the health promotional materials. School-based HPV vaccination programs might be useful.

Vaccines (Basel) 2024; 12:167. [PMID: 38400150 PMCID: PMC10892894 DOI: 10.3390/vaccines12020167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 01/27/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024] Open
Abstract
Introduction: Evidence exists that individual-level sociodemographic factors contribute to vaccine hesitancy, but it is unknown how community-level factors affect COVID-19 booster dose hesitancy. The current study aims to fill this knowledge gap by comparing data from a nationwide survey on COVID-19 vaccine hesitancy with a community-level indicator, i.e., the Distressed Communities Index (DCI). Methods: Attitudes toward vaccinations, vaccine literacy, COVID-19 vaccine confidence index, and trust were measured using a 48-item, psychometrically valid and reliable survey tool. In this study, 2138 survey participants residing in the United States were divided into quintiles of varying community distress levels based on their zip codes using the DCI. Data were analyzed through Chi-square, one-way ANOVA, and post hoc analysis with Tukey's test. Results: A significantly higher proportion of participants from the distressed communities had lower trust than their prosperous counterparts (26.6% vs. 37.6%, p < 0.001). On the contrary, participants from the prosperous communities had significantly higher vaccine confidence index scores than those in distressed communities (2.22 ± 1.13 vs. 1.70 ± 1.01, p < 0.001). Conclusions: These findings affirm the importance of developing community-level interventions to promote trust in COVID-19 vaccinations and increase booster dose uptake. From these results, future studies can examine the efficacy of various community-level interventions.

McKinley CJ, Limbu Y. Promoter or barrier? Assessing how social media predicts Covid-19 vaccine acceptance and hesitancy: A systematic review of primary series and booster vaccine investigations. Soc Sci Med 2024; 340:116378. [PMID: 38042027 DOI: 10.1016/j.socscimed.2023.116378] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 10/23/2023] [Accepted: 10/26/2023] [Indexed: 12/04/2023]
Abstract
RATIONALE Prior research indicates that social media is primarily a negative contributor to Covid-19 vaccine outcomes. OBJECTIVE The current systematic review of Covid-19 primary series and booster vaccine investigations provides a more nuanced and comprehensive assessment of this association by exploring a) how distinct social media judgments and actions predict different vaccine-related outcomes - perceptions and intentions/uptake, b) both primary series and booster findings, c) types of social media, and d) comparisons across different populations. METHOD We conducted a systematic review of published research examining the link between social media and COVID-19 vaccine outcomes - judgments, intentions, and uptake. Overall, we identified 113 published articles. RESULTS The findings reveal complex associations between distinct social media predictors and these outcomes. The most consistent negative relationships emerge within studies looking at 'social media as an information source,' 'trust', and 'general social media use/passive exposure' as predictors of less favorable vaccine judgments and intentions/uptake. Conversely, studies focused on 'information seeking' indicate more mixed results. Among the few booster investigations, there are more positive than negative associations between social media predictors and Covid-19 vaccine intentions. Across different social media platforms and sample populations, social media was a less robust/consistent negative predictor of COVID-19 judgments and intentions. CONCLUSIONS While social media can contribute to more negative COVID-19 vaccine judgments and motivations, the consistency of this relationship may vary across populations, the platforms users access, and the nature of exposure. Overall, social media campaigns promoting COVID-19 vaccines should employ distinct strategies to target those individuals that value social media as an information resource.

Potential motivators affecting parental intention in COVID-19 vaccination for children aged 6 months to 4 years: Implications for targeted vaccine interventions in Japan. Hum Vaccin Immunother 2023; 19:2296737. [PMID: 38112133 PMCID: PMC10732636 DOI: 10.1080/21645515.2023.2296737] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 12/14/2023] [Indexed: 12/20/2023] Open
Abstract
Although COVID-19 vaccination was approved for younger children in Japan in October 2022, uptake rates remain critically low. This study aimed to investigate Japanese parents' intentions, hesitators' probability of positive intention change, and factors that motivate COVID-19 vaccination. Parents with a 6-month to 4-year-old child living in Japan participated in this internet-based, cross-sectional survey conducted from December 19, 2022, to January 4, 2023. The modified Poisson regression analysis was used to assess the probabilities of changing intention by each motivator when comparing the degree of hesitancy among hesitators, and the Poisson generalized estimating equations were used to compare the probabilities of changing intentions by potential motivators within hesitant individuals. Among 12,502 participants, 10,008 (80.1%) were hesitators. Parents with lower hesitancy levels were more likely to be motivated to vaccinate their children through potential motivators. Vaccine hesitators were motivated to vaccinate their children, particularly by proven vaccine effectiveness (including "protecting children from getting sick" with a probability ratio [PR] of 3.7 [95% confidence interval (CI) 3.5-3.9] and "less likely to infect adults" with a PR of 2.9 [95% CI 2.8-3.1]), as well as vaccine safety (including "safe vaccination of millions of children" with a PR of 3.1 [95% CI 3.0-3.3]) compared to injunctive norm (including "community leader recommendation"). Therefore, initially addressing parents with low hesitancy levels is an effective strategy that motivates COVID-19 vaccination. Also, providing evidence-based information about COVID-19 vaccine efficacy and safety that is consistent with parents' needs is crucial.

Abstract
Over 16 million children have been detected positive for the coronavirus disease 2019 (COVID-19) in the United States since the outbreak of the pandemic. In general, children infected with severe acute respiratory syndrome coronavirus type 2 tend to have lighter symptoms than adults. However, in some cases, the infection can develop into severe forms, such as multisystem inflammatory syndrome in children. Moreover, long-term public health preventive interventions have had some negative effects on the physical and mental health of children. Given the important role that vaccination plays in reducing severe illness and mortality, it is essential for the efficient implementation of vaccination in the pediatric population. Nevertheless, parental distrust of vaccination, especially with regard to its safety and efficacy, hinders this process. Herein, we comprehensively summarize the available data on the safety and effectiveness of COVID-19 vaccine in children. The results show that the currently approved COVID-19 vaccine is safe and effective for children. Although two doses of vaccine in children seem insufficient to prevent Omicron infection, the booster dose provides enhanced protection against infection and severe illness. Most importantly, the bivalent vaccine has been approved for use in the pediatric population to extend the immune response to currently circulating Omicron variant. And the immune protection afforded to newborns after maternal vaccination appears to last only 6 months. Therefore, in the current situation where the rate of virus mutation is accelerating and the COVID-19 pandemic is still severe, it is crucial to extend vaccine protection to children over 6 months of age to weave a tighter safety net.

Abstract
This study aimed to investigate the associations between COVID-19 vaccination status and self-reported SARS-CoV-2 infection among children and adolescents aged 3-17 years during a massive COVID-19 outbreak after China changed its zero COVID policy. A cross-sectional online survey was conducted between 1 and 9 March 2023. Participants were the parents of children studying in kindergartens, primary schools, or secondary schools in Shenzhen. Convenient sampling was used. All kindergartens, primary schools, and secondary schools in the Longhua District of Shenzhen invited the parents of children and adolescents attending the schools. Interested parents completed an online survey. Multivariate logistic regression was fitted. Among 8538 participants, 40.9% self-reported that their children had SARS-CoV-2 infection after 7 December 2022, where 92.9% of them received two doses of the COVID-19 vaccines, and 74.6% received their second dose for more than six months. In multivariate analysis, children who received their second dose of the COVID-19 vaccination for no more than three months had a lower SARS-CoV-2 infection rate compared to unvaccinated children (<1 month: AOR: 0.17, 95% CI: 0.07, 0.44; 1-3 months: AOR: 0.54, 95% CI: 0.41, 0.75). The duration of protection conferred by the primary COVID-19 vaccination series was relatively short among children. A booster dose should be considered for children.

Abstract
A second COVID-19 vaccine booster dose is effective and safe for older adults. This study investigated hesitancy to take up a second COVID-19 vaccine booster dose and its determinants among older adults in Hong Kong. Participants were Chinese-speaking community-dwelling adults aged 65 years or above. Telephone numbers were randomly selected from up-to-date telephone directories. A total of 370 participants completed the telephone survey. Logistic regression models were fitted for data analysis. Among the participants, half (52.4%) were hesitant to receive the second COVID-19 vaccine booster dose. After adjustment for significant background characteristics, perceived benefits (AOR: 0.50, 95%CI: 0.42, 0.60), cues to action (AOR: 0.39, 95%CI: 0.30, 0.52), and perceived self-efficacy (AOR: 0.37, 95%CI: 0.21, 0.66) of receiving the second booster dose were associated with lower vaccine hesitancy. Perceived barriers (AOR: 1.23, 95%CI: 1.12, 1.34) and vaccine fatigue (tired of receiving repeated COVID-19 vaccination) (AOR: 1.90, 95%CI: 1.52, 2.38) were associated with higher vaccine hesitancy. Level of hesitancy to receive the second booster dose was high among older adults in Hong Kong. Health authorities should address vaccine fatigue and modify perceptions related to the second booster dose.

Abstract
PURPOSE Caregivers who oppose topical fluoride in dental settings may be opposed to other preventive health treatments, including COVID-19 vaccines. The study objective was to examine the association between caregiver opposition to topical fluoride and COVID-19 vaccines. METHODS The study took place at the University of Washington in Seattle, WA. English-speaking caregivers of children aged < 18 years were eligible to participate. An 85-item REDCap survey was administered from February to September 2021. The predictor variable was topical fluoride opposition (no/yes). The outcome was COVID-19 vaccine opposition (no/yes). The models included the following covariates: child and caregiver age; caregiver race and ethnicity, education level, dental insurance type, parenting style, political ideology, and religiosity; and household income. Logistic regression models generated odds ratios (OR) and 95 % confidence intervals (α = 0.05). RESULTS Six-hundred-fifty-one caregivers participated, and 403 caregivers with complete data were included in the final regression model. Mean child age was 8.5 years (SD 4.2), mean caregiver age was 42.1 years (SD 9.1), 53.0 % of caregivers were female, 57.3 % self-reported as white, and 65.5 % were insured by Medicaid. There was a significant positive association between topical fluoride and COVID-19 vaccine opposition (OR = 3.13; 95 % CI: 1.87, 5.25; p < 0.001). Other factors associated with COVID-19 vaccine opposition included conservative political views (OR = 2.77; 95 % CI: 1.26, 6.08; p < 0.011) and lower education (OR = 3.47; 95 % CI: 1.44, 8.38; p < 0.006). CONCLUSIONS Caregivers opposed to topical fluoride in dental settings were significantly more likely to oppose COVID-19 vaccines for their child. Future research should identify ways to address both topical fluoride and vaccine opposition to prevent diseases in children.

Changes in COVID-19 Vaccine Acceptability among Parents with Children Aged 6-35 Months in China-Repeated Cross-Sectional Surveys in 2020 and 2021. Vaccines (Basel) 2023; 11:vaccines11010170.

Abstract
China is considering to offer COVID-19 vaccination for children aged 6−35 months. This study investigated the changes in COVID-19 vaccine acceptability and associated factors among parents with children aged 6−35 months in 2020 and 2021. Two rounds of cross-sectional online surveys were conducted among adult factory workers in Shenzhen, China. A subset of 208 (first round) and 229 (second round) parents with at least one child aged 6−35 months was included in the study. Parental acceptability of COVID-19 vaccination increased significantly from 66.8% in the first round to 79.5% in the second round (p = 0.01). Positive attitudes, perceived subjective norm, and perceived behavioral control were associated with higher parental acceptability in both rounds of surveys (p values ranged from <0.001 to 0.003). A negative association of negative attitudes with parental acceptability was observed in the second round (p = 0.02). No significant associations of exposure to information related to COVID-19 vaccination on social media with parental acceptability was found in either round of survey. Expanding the existing COVID-19 vaccination programs to cover children aged 6−35 months is necessary in China. Future programs should focus on modifying perceptions among parents to promote COVID-19 vaccination for children in this age group.
