COVID-19 Vaccine Acceptance Among US Parents: A Nationally Representative Survey

COVID-19 Vaccine Hesitancy in Caregivers of Hospitalized Children From 2020 Through 2023

OBJECTIVES

Data on US caregiver perceptions on coronavirus disease 2019 (COVID-19) and COVID-19 vaccination are limited. We identified trends in and associations with COVID-19 vaccine hesitancy in caregivers of hospitalized children.

METHODS

Cross-sectional surveys on pediatric COVID-19 disease and vaccine attitudes, behaviors, and beliefs were administered across study years (December 8, 2020-April 5, 2021, November 30, 2021-March 15, 2022, and October 26, 2022-March 15, 2023). English and Spanish-speaking caregivers of hospitalized children ages 6 months to 11 years were included. General vaccine hesitancy was assessed using the Parent Attitudes about Childhood Vaccines survey.

RESULTS

Of 1268 caregivers from diverse backgrounds, one-third vaccinated or intended to vaccinate their child. Half endorsed fear of their child receiving the COVID-19 vaccine and were concerned the vaccine was new. Over time, more believed "the COVID-19 vaccine does not work" and fewer agreed "children who are otherwise healthy can die from COVID-19." Study season (2022-2023), older child age, higher income, child receipt of influenza vaccine, caregiver receipt of COVID-19 vaccine, and not being worried about vaccine novelty were positively associated with child vaccination. Intent to vaccinate was negatively associated with study season (2022-2023), Parent Attitudes about Childhood Vaccines score ≥50, lack of child influenza and caregiver COVID-19 vaccination, lack of fear of their child "getting COVID-19" and being "worried that the COVID-19 vaccine is new." The majority who intended to vaccinate were willing to immunize before discharge.

CONCLUSIONS

Vaccine novelty and perceived lack of need were associated with refusal. Caregiver COVID-19 and child influenza vaccine acceptance were positively associated with COVID-19 vaccine acceptance. The inpatient setting offers the opportunity to improve vaccine uptake.

A health equity science approach to assessing drivers of COVID-19 vaccination coverage disparities over the course of the COVID-19 pandemic, United States, December 2020-December 2022

INTRODUCTION

Health equity science examines underlying social determinants, or drivers, of health inequities by building an evidence base to guide action across programs, public health surveillance, policy, and communications efforts. A Social Vulnerability Index (SVI) was utilized during the COVID-19 response to identify areas where inequities exist and support communities with vaccination. We set out to assess COVID-19 vaccination coverage by two SVI themes, Racial and Ethnicity Minority Status and Housing Type and Transportation to examine disparities.

METHODS

US county-level COVID-19 vaccine administration data among persons aged 5 years and older reported to the Centers for Disease Control and Prevention from December 14, 2020 to December 14, 2022, were analyzed. Counties were categorized 1) into tertiles (low, moderate, high) according to each SVI theme's level of vulnerability or 2) dichotomized by urban or rural classification. Primary series vaccination coverage per age group were assessed for SVI social factors by SVI theme tertiles or urbanicity.

RESULTS

Older adults aged 65 years and older had the highest vaccination coverage across all vulnerability factors compared with children aged 5-17 years and adults aged 18-64 years. Overall, children and adults had higher vaccination coverage in counties of high vulnerability. Greater vaccination coverage differences were observed by urbanicity as rural counties had some of the lowest vaccination coverage for children and adults.

CONCLUSION

COVID-19 vaccination efforts narrowed gaps in coverage for adults aged 65 years and older but larger vaccination coverage differences remained among younger populations. Moreover, greater disparities in coverage existed in rural counties. Health equity science approaches to analyses should extend beyond identifying differences by basic demographics such as race and ethnicity and include factors that provide context (housing, transportation, age, and geography) to assist with prioritization of vaccination efforts where true disparities in vaccination coverage exist.

Navigating parental attitudes on childhood vaccination in Jordan: a cross-sectional study

This study investigated parental attitudes toward childhood vaccination in Jordan, focusing on acceptance, concerns, and perceptions. A cross-sectional survey conducted from January to February 2024 included 939 parents. Findings indicated that 85.4% (n = 802) of respondents received the COVID-19 vaccine, while only 25% (n = 229) vaccinated their children. Concerns regarding vaccine safety and efficacy were prevalent, with 63.9% (n = 600) expressing worries about side effects and 46.9% (n = 440) trusting immunization programs. Post-pandemic, 34% (n = 319) reported a more negative attitude. Logistic regression showed parents not vaccinating their children against COVID-19 were significantly less likely to exhibit positive attitudes toward childhood vaccination (OR = 0.412, p < 0.001). Older participants were more inclined toward negativity post-pandemic (OR = 1.031, p = 0.007). In conclusion, parental attitudes shifted post-COVID-19, reflecting hesitancy and decreased trust. Addressing concerns and restoring confidence are crucial, especially for children's health. Education through healthcare providers and dispelling social media misinformation are essential. Implementing strategies to enhance post-pandemic vaccine acceptance is imperative for preventing outbreaks of vaccine-preventable diseases.

Latino Parents' Reactions to and Engagement With a Facebook Group-Based COVID-19 Vaccine Promotion Intervention: Mixed Methods Pilot Study

BACKGROUND

Misinformation in Spanish on social media platforms has contributed to COVID-19 vaccine hesitancy among Latino parents. Brigada Digital de Salud was established to disseminate credible, science-based information about COVID-19 in Spanish on social media.

OBJECTIVE

This study aims to assess participants' reactions to and engagement with Brigada Digital content that sought to increase COVID-19 vaccine uptake among US Latino parents and their children.

METHODS

We conducted a 5-week intervention in a private, moderator-led Facebook (Meta Platforms, Inc) group with Spanish-speaking Latino parents of children aged ≤18 years (N=55). The intervention participants received 3 to 4 daily Brigada Digital posts and were encouraged to discuss the covered topics through comments and polls. To assess participants' exposure, reactions, and engagement, we used participants' responses to a web-based survey administered at 2 time points (baseline and after 5 weeks) and Facebook analytics to calculate the average number of participant views, reactions, and comments. Descriptive statistics were assessed for quantitative survey items, qualitative responses were thematically analyzed, and quotes were selected to illustrate the themes.

RESULTS

Overall, 101 posts were published. Most participants reported visiting the group 1 to 3 times (22/55, 40%) or 4 to 6 (18/55, 33%) times per week and viewing 1 to 2 (23/55, 42%) or 3 to 4 (16/55, 29%) posts per day. Facebook analytics validated this exposure, with 36 views per participant on average. The participants reacted positively to the intervention. Most participants found the content informative and trustworthy (49/55, 89%), easy to understand, and presented in an interesting manner. The participants thought that the moderators were well informed (51/55, 93%) and helpful (50/55, 91%) and praised them for being empathic and responsive. The participants viewed the group environment as welcoming and group members as friendly (45/55, 82%) and supportive (19/55, 35%). The 3 most useful topics for participants were the safety and efficacy of adult COVID-19 vaccines (29/55, 53%), understanding child risk levels (29/55, 53%), and the science behind COVID-19 (24/55, 44%). The preferred formats were educational posts that could be read (38/55, 69%) and videos, including expert (28/55, 51%) and instructional (26/55, 47%) interviews. Regarding engagement, most participants self-reported reacting to posts 1 to 2 (16/55, 29%) or 3 to 4 (15/55, 27%) times per week and commenting on posts 1 to 2 (16/55, 29%) or <1 (20/55, 36%) time per week. This engagement level was validated by analytics, with 10.6 reactions and 3 comments per participant, on average, during the 5 weeks. Participants recommended more opportunities for engagement, such as interacting with the moderators in real time.

CONCLUSIONS

With adequate intervention exposure and engagement and overall positive participant reactions, the findings highlight the promise of this digital approach for COVID-19 vaccine-related health promotion.

Patient receptivity to receiving vaccinations in the dental clinic at a rural federally qualified health center

BACKGROUND

More than 28 million people in the United States visited their dentists but not a physician in 2018, yet only a few states allow dentists to administer vaccines to patients, and those vaccines are limited to influenza, COVID-19, and human papillomavirus.

METHODS

To assess the receptiveness of adult dental patients and caregivers of pediatric dental patients to receive necessary vaccines during their dental appointment, a survey was distributed to patients attending a dental visit at a rural federally qualified health center from June 28, 2021, through December 31, 2021.

RESULTS

Among the responses from 643 adult patients and 625 pediatric caregivers, approximately one-half (54.2% and 49.9%, respectively) reported being receptive to receiving vaccines in the dental clinic, with 28.5% and 21.8% not being receptive to vaccines, respectively. Primary language, age group, number of children, and primary care center all were associated significantly with reported likelihood of receiving vaccines (P < .05). The most reported concern about receiving vaccines at a dental clinic was a preference for their primary care physician to provide all vaccinations, according to 22.2% of adult patients and 39.8% of pediatric caregivers.

CONCLUSIONS

The authors' findings support efforts to administer vaccines during dental visits to improve immunization rates among adults and children. Ongoing communication with primary care physicians regarding administration of vaccines in the dental clinic could reduce concerns by adult patients and pediatric caregivers.

PRACTICAL IMPLICATIONS

Strategies and policies that establish protocols to ensure the safe and effective administration of vaccines in dental visits should be implemented and supported.

Understanding caregivers' decision to vaccinate childhood cancer survivors against COVID-19

BACKGROUND

Vaccination against COVID-19 is recommended for childhood cancer survivors (CCS). This study aimed to identify antecedents contributing to caregivers' decisions to vaccinate CCS aged 5-17 years against COVID-19 by applying the Theory of Planned Behavior.

METHODS

Participants in this cross-sectional study completed an online survey assessing caregiver attitudes, subjective norms, perceived behavioral control, intention to vaccinate CCS, CCS vaccination status, COVID-19 health literacy, and frequency of COVID-19 information-seeking. Surveys were completed between May and June 2022 following approval for the emergency use of COVID-19 vaccines among children aged ≥5 years in the U.S. Data were analyzed using unadjusted linear regressions and structural equation modeling.

RESULTS

Participants were caregivers (n = 160, 87.5% biological mothers, 75.6% white/non-Hispanic) of CCS (n = 160, 44.4% female, mean (M) = 12.5 years old, M = 8.0 years off treatment). 70.0% (n = 112) of caregivers and 53.8% (n = 86) of CCS received a COVID-19 vaccine. Over one-third (37.5%) of caregivers reported disagreement or indecision about future COVID-19 vaccination for the CCS. Caregivers' intention (β = 0.962; standard error [S.E.] = 0.028; p < 0.001) was highly related to CCS vaccination status. Attitudes (β = 0.568; S.E. = 0.078; p < 0.001) and subjective norms (β = 0.322; S.E. = 0.062; p < 0.001) were associated with intention. Higher frequency of COVID-19 information-seeking (β = 0.313; S.E. = 0.063; p < 0.001) and COVID-19 health literacy (β = 0.234; S.E. = 0.059; p < 0.001) had a positive indirect effect on intention through attitudes and subjective norms.

CONCLUSIONS

Caregivers' vaccination intentions for minor CCS are highly related to vaccination behavior and shaped by attitudes, subjective norms, COVID-19 health literacy, and frequency of COVID-19 information-seeking. Promoting tailored communication with caregivers of CCS and encouraging them to review reputable sources of information can address their vaccine hesitancy.

COVID-19 vaccination attitudes, values, intentions: US parents for their children, September 2021

OBJECTIVES

To compare vaccine-related attitudes and values of parents of children 2-17 years old to other adults, examine intentions to vaccinate their children, and identify factors associated with intending to vaccinate children.

METHODS

A nationally representative survey was conducted in September 2021 (just before the EUA for children 5-11 years old) using Ipsos KnowledgePanel, a probability-based web panel. The survey measured COVID-19 vaccination status, intentions, attitudes, values, and trust in public health authorities among US adults. Scale response options to survey items were dichotomized, and cross-tabulations and logistic regressions were performed.

RESULTS

Parents had lower odds of reporting being vaccinated against COVID-19 than other adults even after adjusting for associated sociodemographic characteristics such as age (aOR: 0.66; 95 %CI: 0.50-0.87). The most prevalent parental concerns about COVID-19 vaccines included the speed of their development (88 %), potential side effects (78 %), suspicion of government (77 %), and suspicion of pharmaceutical companies (72 %). Fewer than half (42 %) of parents intended to vaccinate their children 5-11 years old, while 38 % were uncertain and 20 % were unlikely to ever vaccinate their children. Vaccinated parents had higher odds than unvaccinated parents of intending to vaccinate their children (OR: 675.51; 95 %CI: 106.46-4286.12). Discussions with healthcare providers who encouraged COVID-19 vaccination were positively associated with intent to vaccinate children (OR: 11.29; 95 %CI: 2.60-49.02).

CONCLUSIONS

We found parental vaccination and conversations with providers were positively associated with intent to vaccinate children. Decisions about childhood vaccination need to be supported by healthcare providers and a public health system that makes vaccine access and related information equitable and accessible. Vaccination-related decision making should be guided by healthcare providers and provide information about safety and risk to children.

Attitudes toward COVID-19 and Other Vaccines: Comparing Parents to Other Adults, September 2022

Few analyses of COVID-19 vaccine attitudes also cover routine vaccines or focus on parents. In this cross-sectional study, we surveyed US adults in September 2022, immediately following the authorization of updated bivalent COVID-19 boosters for adults but before their authorization for children. The vaccine attitudes of parents were compared to other adults. Fewer parents were up-to-date on COVID-19 vaccines than other adults (54% vs. 67%), even after adjusting for age, education, and race/ethnicity (Adjusted Odds Ratio: 0.58; 95% Confidence Interval: 0.45-0.76). More parents had concerns about COVID-19 vaccines' safety in children (67% vs. 58%; aOR: 1.59; 95%CI: 1.23-2.06) and vaccine ingredients (52% vs. 45%; aOR: 1.41; 95%CI: 1.09-1.81), and more parents perceived COVID-19 in children to be no worse than a cold or the flu (51% vs. 38%; aOR: 1.56; 95%CI: 1.22-2.01). Fewer parents supported COVID-19 vaccine school requirements (52% vs. 57%; aOR: 0.75; 95%CI: 0.58-0.97) and perceived high vaccine coverage among their friends (51% vs. 61%; aOR: 0.60; 95%CI: 0.46-0.78). However, three-quarters of parents intended their child to receive all routinely recommended vaccines, whereas only half of adults intended to receive all routinely recommended vaccines themselves. To improve parental informed vaccine decision-making, public health must ensure pediatric providers have updated resources to support their discussions of vaccine risks and benefits with their patients' parents.

Assessing Changes in COVID-19 Vaccine Uptake and Intentions among the Brigada Digital Latino Social Media Audience: A Repeated Cross-Sectional Study

BACKGROUND

U.S. Latinos experienced disproportionate COVID-19 impacts in terms of morbidity and mortality. Vaccination against COVID-19 is an important strategy for mitigating health impacts, and yet, vaccine uptake was slower among U.S. Latino adults compared to other racial/ethnic groups. Vaccine hesitancy has been a significant barrier within Latino communities, and exposure to misinformation has been associated with negative attitudes toward vaccination. While some COVID-19 mitigation efforts have included community-based outreach, few studies have explored the impact of community-based digital messaging in Spanish to counter COVID-19 misinformation, build trust, and promote vaccination.

METHODS

To address this gap, we conducted a one-year repeated cross-sectional study to assess changes in COVID-19 vaccine uptake, intentions, and perceived norms, as well as barriers to accessing reliable information and levels of trust in COVID-19 information sources among Latino adults exposed to Brigada Digital de Salud social media content. This culturally-tailored content disseminated on Facebook, Instagram, and X platforms was amplified by community health workers and partners, and focused on COVID-19 risk and prevention, vaccine safety and efficacy, and correcting related misinformation.

RESULTS

Statistically significant increases in COVID-19 vaccination, intentions to vaccinate children, and vaccination subjective norms were observed from May 2022 (wave 1) to April 2023 (wave 2). Among perceived difficulties accessing information, respondents indicated the most difficulty in judging the reliability of COVID-19 information in the media; however, a statistically significant decrease in perceived difficulty was observed between waves. With regard to trust in COVID-19 information sources, levels of trust were highest for healthcare providers in both waves. From wave 1 to wave 2, there were statistically significant increases in trust in the FDA to ensure COVID-19 vaccine safety and trust in the federal government to ensure child COVID-19 vaccine safety.

CONCLUSIONS

Social media messaging by trusted community-based sources shows promise as a strategy for combating health misinformation and ameliorating information access gaps for language minority populations. This digital approach represents an important tool for deploying critical information to underserved populations in public health emergency and crisis contexts, and for supporting changes in attitudes, trust, and behaviors to improve health outcomes.

Analysis of the COVID-19 vaccine willingness and hesitancy among parents of healthy children aged 6 months-4 years: a cross-sectional survey in Italy

Introduction

In Italy, since December 2022, the COVID-19 vaccination has been extended to children aged 6 months-4 years with conditions of fragility and to those healthy at the request of the parent. The purposes of the cross-sectional survey were to determine the willingness and hesitancy of the parents/guardians to have their healthy children vaccinated against COVID-19.

Methods

The survey was performed among 389 parents/guardians with a child aged 6 months-4 years randomly selected from seven kindergartens and eight nursery schools in the geographic area of Naples, Italy.

Results

Only 10.5% were very concerned about the risk of infection, and the mean values regarding the perceived utility and safety of the COVID-19 vaccine were 3.3 and 3.2, respectively. Only 13.7% of participants were willing to consent to vaccinate the selected child against COVID-19, while 20.1% were uncertain and 66.2% did not intend. Parents/guardians of older children, those who received information about the COVID-19 vaccine from physicians or pediatricians, those who believed that the COVID-19 vaccine was useful, and those with lower hesitancy regarding the COVID-19 vaccine were more willing to vaccinate their child. The mean Parent Attitudes About Childhood Vaccines (PACV-5) score was 5.6, with 33.1% of respondents who were identified as highly hesitant toward COVID-19 vaccination (score ≥ 7). Parents/guardians with a lower perceived safety of the COVID-19 vaccine were more likely to be highly hesitant.

Discussion

The findings reveal the need to improve community-based education campaigns and effective promotion of the COVID-19 vaccination to increase willingness and address parental safety concerns.

Awareness of Multisystem Inflammatory Syndrome in Children Among US Parents: A Cross-Sectional Survey

Background

Little is known about parental awareness of multisystem inflammatory syndrome in children (MIS-C), a rare but severe sequela of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Methods

Via a nationally representative, cross-sectional survey of US parents conducted via Ipsos KnowledgePanel from October to November 2021, we used bivariate and multivariable analyses to describe and identify demographic variables associated with parental knowledge of and attitudes toward MIS-C and to examine associations with perceived coronavirus disease 2019 (COVID-19) severity and susceptibility.

Results

Response rate was 64.2% (3230/5034). Thirty-two percent of respondents had heard of MIS-C. After adjustment, higher educational level (compared to high school degree; some college: odds ratio [OR], 2.00 [95% confidence interval {CI}, 1.44-2.77]; bachelor's degree or higher: OR, 3.14 [95% CI, 2.26-4.35]), being a healthcare worker (OR, 1.82 [95% CI, 1.37-2.42]), having a child with a chronic medical condition (OR, 1.62 [95% CI, 1.22-2.14]), and experience with more severe COVID-19 (OR, 1.46 [95% CI, 1.14-1.86]) were associated with MIS-C awareness. Respondents with a child aged 12-17 years were less likely to be aware of MIS-C compared to those without (OR, 0.78 [95% CI, .63-.96]), as were male respondents (OR, 0.56 [95% CI, .46-.69]) and respondents aged 18-34 years (OR, 0.72 [95% CI, .54-.94]) compared to those aged 35-44 years. Awareness of MIS-C was associated with higher perceived COVID-19 severity and susceptibility (regression coefficients, 0.18 [95% CI, .10-.25], P < .001; 0.19 [95% CI, .11-.28], P < .001, respectively).

Conclusions

This survey highlights the need to increase parental awareness of MIS-C. Future studies should explore how education regarding MIS-C as a complication of SARS-CoV-2 infection could improve understanding of pediatric disease severity and susceptibility.

Myocarditis and Pericarditis Post-mRNA COVID-19 Vaccination: Insights from a Pharmacovigilance Perspective

Concerns remain regarding the rare cardiovascular adverse events, myocarditis and pericarditis (myo/pericarditis), particularly in younger individuals following mRNA COVID-19 vaccination. Our study aimed to comprehensively assess potential safety signals related to these cardiac events following the primary and booster doses, with a specific focus on younger populations, including children as young as 6 months of age. Using the Vaccine Adverse Events Reporting System (VAERS), the United States national passive surveillance system, we conducted a retrospective pharmacovigilance study analyzing spontaneous reports of myo/pericarditis. We employed both frequentist and Bayesian methods and conducted subgroup analyses by age, sex, and vaccine dose. We observed a higher reporting rate of myo/pericarditis following the primary vaccine series, particularly in males and mainly after the second dose. However, booster doses demonstrated a lower number of reported cases, with no significant signals detected after the fourth or fifth doses. In children and young adults, we observed notable age and sex differences in the reporting of myo/pericarditis cases. Males in the 12-17 and 18-24-year-old age groups had the highest number of cases, with significant signals for both males and females after the second dose. We also identified an increased reporting for a spectrum of cardiovascular symptoms such as chest pain and dyspnea, which increased with age, and were reported more frequently than myo/pericarditis. The present study identified signals of myo/pericarditis and related cardiovascular symptoms after mRNA COVID-19 vaccination, especially among children and adolescents. These findings underline the importance for continued vaccine surveillance and the need for further studies to confirm these results and to determine their clinical implications in public health decision-making, especially for younger populations.

Willingness and hesitancy of parents to vaccinate against COVID-19 their children ages 6 months to 4 years with frail conditions in Italy

Background

In Italy, on December 2022, COVID-19 vaccination was recommended for children aged 6 months-4 years with frail conditions and for those healthy. The purposes of the survey were to understand parental willingness and hesitancy toward COVID-19 vaccination of children with frail conditions in Italy and related influencing factors.

Methods

A cross-sectional survey was performed among 445 parents with a child aged 6 months-4 years with frail conditions who attended a teaching hospital and a public hospital randomly selected in the city of Naples, Italy.

Results

Almost one third (29.9%) were willing to vaccinate their frail children against COVID-19, whereas 21.3% were uncertain, and 48.8% did not intend to vaccinate. Parents with a higher level of perception that the vaccine is useful and safe and those who had received information by pediatrician were more likely to be willing to vaccinate their child. The mean Parent Attitudes About Childhood Vaccines (PACV-5) score was 3.4, with 13.5% of parents high-hesitant for the COVID-19 vaccination for their child. Parents with a higher COVID-19 vaccine-related safety concerns, those who have delayed at least one shot of a recommended vaccine for their child, and those who did not have received at least three doses of the vaccine against SARS-CoV-2 were more likely to be high-hesitant.

Conclusion

The survey findings have important implications for designing interventions to increase willingness and to reduce hesitancy for COVID-19 vaccine among parents of frail children aged 6 months-4 years in Italy.

Mild Hyperglycaemia in Hospitalised Children with Moderate COVID-19 Infection

Background and Objectives: COVID-19 infection may influence many physiological processes, including glucose metabolism. Acute hyperglycaemia has been related to a worse prognosis in patients with severe COVID-19 infection. The aim of our study was to find out if moderate COVID-19 infection is associated with hyperglycaemia. Materials and Methods: A total of 235 children were enrolled in the study between October 2021 and October 2022, 112 with confirmed COVID-19 infection and 123 with other RNA viral infection. In all patients, types of symptoms, glycaemia at the time of admission, and basic anthropometric and biochemical parameters were recorded. Results: Average glycaemia was significantly higher in COVID-19 patients compared to other viral infections (5.7 ± 1.12 vs. 5.31 ± 1.4 mmol/L, p = 0.011). This difference was more obvious in subgroups with gastrointestinal manifestations (5.6 ± 1.11 vs. 4.81 ± 1.38 mmol/L, p = 0.0006) and with fever (5.76±1.22 vs. 5.11±1.37 mmol/L, p = 0.002), while no significant difference was found in subgroups with mainly respiratory symptoms. The risk of hyperglycaemia (>5.6 mmol/L) was higher in COVID-19 patients compared to other viral infections (OR = 1.86, 95%CI = 1.10-3.14, p = 0.02). The risk of hyperglycaemia was significantly higher in COVID-19 compared to other viral infections in the subgroups of patients with fever (OR = 3.59, 95% CI 1.755-7.345, p = 0.0005) and with gastrointestinal manifestations (OR = 2.48, 95% CI 1.058-5.791, p = 0.036). Conclusion: According to our results, mild hyperglycaemia was significantly more common in children with moderate COVID-19 infection compared to other RNA virus respiratory and gastrointestinal infections, especially when accompanied by fever or gastrointestinal symptoms.

Factors impacting parental uptake of COVID-19 vaccination for U.S. Children ages 5-17

COVID-19 vaccination of U.S. children lags behind adult vaccination, but remains critical in mitigating the pandemic. Using a subset of a nationally representative survey, this study examined factors contributing to parental uptake of COVID-19 vaccine for children ages 12-17 and 5-11, stratified by parental COVID-19 vaccination status. Among vaccinated parents, uptake was higher for 12-17-year-olds (78.6%) than 5-11-year-olds (50.7%); only two unvaccinated parents vaccinated their children. Child influenza vaccination was predictive of uptake for both age groups, while side effect concerns remained significant only for younger children. Although parents were more likely to involve adolescents in vaccine decision-making than younger children, this was not predictive of vaccine uptake. These results highlight the importance of addressing the unique and shared concerns parents have regarding COVID-19 vaccination for children of varying ages. Future work should further explore adolescent/child perspectives of involvement in COVID-19 vaccination decision-making to support developmentally appropriate involvement.

Coronavirus Disease-2019 Vaccine Hesitancy

Early in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, before coronavirus disease-2019 (COVID-19) vaccines were authorized, surveys began tracking public acceptance of a hypothetical COVID-19 vaccine. As vaccines became more widely available, the focus shifted from evaluating premeditative thoughts about COVID-19 vaccines to observing behaviors, measuring uptake, and characterizing factors associated with acceptance. A wealth of peer-reviewed literature examining the complexities of COVID-19 vaccine acceptance has emerged, but our understanding of COVID-19 vaccine acceptance is constantly evolving. In this article, we review the current state of knowledge regarding COVID-19 vaccine hesitancy, with an emphasis on pediatric vaccination.

Assessment of Efficacy and Safety of mRNA COVID-19 Vaccines in Children Aged 5 to 11 Years: A Systematic Review and Meta-analysis

Importance

Evidence of the efficacy and safety of messenger RNA (mRNA) COVID-19 vaccines in children aged 5 to 11 years has been emerging. Collecting these data will inform clinicians, families, and policy makers.

Objective

To evaluate the efficacy and safety of mRNA COVID-19 vaccines in children aged 5 to 11 years in a systematic review and meta-analysis.

Data Sources

PubMed and Embase databases were searched on September 29, 2022, without language restrictions.

Study Selection

Randomized clinical trials and observational studies comparing vaccinated vs unvaccinated children aged 5 to 11 years and reporting efficacy or safety outcomes were included. Studies reporting safety outcomes in vaccinated children only (ie, no control group) were also included.

Data Extraction and Synthesis

Two investigators independently extracted relevant data from each study. Odds ratios (ORs) for efficacy and safety outcomes and incidences of adverse events (AEs) following vaccination were synthesized using a random-effects model. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses and Meta-analysis of Observational Studies in Epidemiology reporting guidelines.

Main Outcomes and Measures

The primary outcome was SARS-CoV-2 infections with or without symptoms. The secondary outcomes included symptomatic SARS-CoV-2 infections, hospitalizations, and multisystem inflammatory syndrome in children. The incidences of each AE following vaccination were also evaluated.

Results

Two randomized clinical trials and 15 observational studies involving 10 935 541 vaccinated children (median or mean age range, 8.0-9.5 years) and 2 635 251 unvaccinated children (median or mean age range, 7.0-9.5 years) were included. Two-dose mRNA COVID-19 vaccination compared with no vaccination was associated with lower risks of SARS-CoV-2 infections with or without symptoms (OR, 0.47; 95% CI, 0.35-0.64), symptomatic SARS-CoV-2 infections (OR, 0.53; 95% CI, 0.41-0.70), hospitalizations (OR, 0.32; 95% CI, 0.15-0.68), and multisystem inflammatory syndrome in children (OR, 0.05; 95% CI, 0.02-0.10). Two randomized clinical trials and 5 observational studies investigated AEs among vaccinated children. Most vaccinated children experienced at least 1 local AE following the first injection (32 494 of 55 959 [86.3%]) and second injection (28 135 of 46 447 [86.3%]). Vaccination was associated with a higher risk of any AEs compared with placebo (OR, 1.92; 95% CI, 1.26-2.91). The incidence of AEs that prevented normal daily activities was 8.8% (95% CI, 5.4%-14.2%) and that of myocarditis was estimated to be 1.8 per million (95% CI, 0.000%-0.001%) following the second injection.

Conclusions and Relevance

In this systematic review and meta-analysis, COVID-19 mRNA vaccines among children aged 5 to 11 years were associated with measures of efficacy in preventing SARS-CoV-2 infection and severe COVID-19-related illnesses. While most children developed local AEs, severe AEs were rare, and most of AEs resolved within several days. These data provide evidence for future recommendations.

Vaccine hesitancy and the willingness to recommend the COVID-19 vaccine to children in a rural country on the United States-Mexico border

Introduction

As of October 26, 2022, only 9% of children in the United States aged 6 months to 4 years have received at least one dose of COVID-19 vaccine despite FDA approval since June 17, 2022. Rates are better yet still low for children aged 5 to 11 years as nearly 30% were fully vaccinated as of August 23, 2022. Vaccine hesitancy among adults is one of the major factors affecting low vaccine uptake rates in children against COVID-19, yet most studies examining vaccine hesitancy have targeted school-age and adolescent children.

Methods

With the aim of assessing the willingness to recommend the COVID-19 vaccination to children under 5 years compared to children 5 to 12 years of age, a county-wide survey was conducted between January 11 and March 7, 2022, among adults on the United States-Mexico border.

Results

Among the 765 responses, 72.5% were female and 42.3% were Latinx. The most significant factor associated with likelihood to recommend the COVID-19 vaccine to children less than 5 years and 5-12 years of age was adult vaccination status. Ordinal logistic regression also indicated that ethnicity, primary language, being a parent, previous COVID-19 infection, and concern about getting COVID-19 in the future were significantly associated with likelihood of COVID-19 vaccine recommendation to children < 5 years and 5-12 years old.

Discussion

This study found high consistency among respondents in their willingness to vaccinate children aged < 5 years compared with children aged 5-12 years. Our findings support public health strategies that target adult vaccinations as an avenue to improve childhood vaccinations for young children.

Barriers and facilitators of childhood COVID-19 vaccination among parents: A systematic review

BACKGROUND

The acceptance of vaccination against COVID-19 among parents of young children plays a significant role in controlling the current pandemic. A wide range of factors that influence vaccine hesitancy in adults has been reported worldwide, but less attention has been given to COVID-19 vaccination among children. Vaccine hesitancy is considered a major challenge in achieving herd immunity, and it is more challenging among parents as they remain deeply concerned about their child's health. In this context, a systematic review of the current literature is inevitable to assess vaccine hesitancy among parents of young children to ensure a successful ongoing vaccination program.

METHOD

A systematic search of peer-reviewed English literature indexed in Google Scholar, PubMed, Embase, and Web of science was performed using developed keywords between 1 January 2020 and August 2022. This systematic review included only those studies that focused on parental concerns about COVID-19 vaccines in children up to 12 years without a diagnosis of COVID-19. Following PRISMA guidelines, a total of 108 studies were included. The quality appraisal of the study was performed by Newcastle-Ottawa Scale (NOS).

RESULTS

The results of 108 studies depict that vaccine hesitancy rates differed globally with a considerably large number of factors associated with it. The highest vaccine hesitancy rates among parents were reported in a study from the USA (86.1%) and two studies from Saudi Arabia (>85%) and Turkey (89.6%). Conversely, the lowest vaccine hesitancy rates ranging from 0.69 and 2% were found in two studies from South Africa and Switzerland, respectively. The largest study (n = 227,740) was conducted in Switzerland while the smallest sample size (n = 12) was represented by a study conducted in the USA. The most commonly reported barriers to childhood vaccination were mothers' lower education level (N = 46/108, 43%), followed by financial instability (N = 19/108, 18%), low confidence in new vaccines (N = 13/108, 12%), and unmonitored social media platforms (N = 5/108, 4.6%). These factors were significantly associated with vaccine refusal among parents. However, the potential facilitators for vaccine uptake among respondents who intended to have their children vaccinated include higher education level (N = 12/108, 11%), followed by information obtained through healthcare professionals (N = 9/108, 8.3%) and strong confidence in preventive measures taken by the government (N = 5/81, 4.6%).

CONCLUSION

This review underscores that parents around the globe are hesitant to vaccinate their kids against COVID-19. The spectrum of factors associated with vaccine hesitancy and uptake varies across the globe. There is a dire need to address vaccine hesitancy concerns regarding the efficacy and safety of approved vaccines. Local context is inevitable to take into account while developing programs to reduce vaccine hesitancy. There is a dire need to devise strategies to address vaccine hesitancy among parents through the identification of attributing factors.
