Purpose: The goal of this study was to assess if caregivers' attitudes toward the regulatory process of approving the vaccine against coronavirus disease 2019 (COVID-19) for children aged <12 years changed after a vaccine was approved for adults., Methods: This was a larger scale COVIPAS (COVID-19 Parental Attitude Study) survey of caregivers presenting with their children aged ≤12 years for emergency care in 12 hospitals in the United States, Canada, and Israel. The study compared willingness to support abridged research into COVID-19 vaccines for children between the peak of the pandemic (March-May 2020) and after a COVID-19 vaccine became available for adults (December 2020-March 2021)., Findings: A total of 1956 surveys were included in the analyses. Overall, 385 (30.9%) caregivers in the pre-vaccine approval period and 250 (35.3%) caregivers in the post-adult vaccine phase supported abridged research into COVID-19 vaccines (P < 0.001). In both phases, mothers were less likely to favor abridged approval. Those with children who were fully vaccinated based on the pediatric schedule in their country favored abridged approval in phase 1 (odds ratio, 1.98; 95% confidence interval, 1.31-3.08) but less so in phase 2. In both phases, age and concerns of parents that they had COVID-19 or their child had COVID-19 were not associated with changes in response between phases., Implications: Willingness to expedite vaccine approval increased after the emergency approval of COVID-19 vaccine for adults. Mothers are much less likely to approve expedited approval. No significant changes have been found in the composition of caregivers willing to forego regulatory demands on vaccine approval., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Vaccinating children against COVID-19 is critical as a public health strategy in order to reach herd immunity and prevent illness among children and adults. The aim of the study was to identify correlation between willingness to vaccinate children under 12 years old, and vaccination rate for adult population in Canada, the United States, and Israel. This was a secondary analysis of a cross-sectional survey study (COVID-19 Parental Attitude Study) of parents of children 12 years and younger presenting to 12 pediatric emergency departments (EDs). Parental reports of willingness to vaccinate against COVID-19 when vaccines for children will be approved was correlated to country-specific rate of vaccination during December 2020-March 2021, obtained from ourworldindata.org. Logistic regression models were fit with covariates for week and the corresponding vaccine rate. A total of 720 surveys were analyzed. In Canada, administering mostly first dose to the adult population, willingness to vaccinate children was trending downward (correlation = -0.28), in the United States, it was trending upwards (correlation = 0.21) and in Israel, initially significant increase with decline shortly thereafter (correlation = 0.06). Odds of willingness to vaccinate in Canada, the United States, and Israel was OR = 0.82, 95% CI = 0.63-1.07, OR = 1.24, 95% CI = 0.99-1.56, and OR = 1.03, 95% CI = 0.95-1.12, respectively. A robust population-based vaccination program as in Israel, and to a lesser degree the United States, led to increasing willingness by parents to vaccinate their children younger than 12 years against COVID-19. In Canada, slow rate of vaccination of the adult population was associated with lower willingness to vaccinate children.

Objective: To determine if caregivers of children presenting to pediatric emergency departments (EDs) during the COVID-19 pandemic are delaying presenting to care for fear of contracting COVID-19., Methods: This was a pre-planned secondary analysis of a cross-sectional survey study of caregivers accompanying their children aged 0-19 years to 16 pediatric EDs in 5 countries from May to June 2020. An anonymous online survey, completed by caregivers via RedCAP, included caregiver and child demographics, presenting complaints, if they delayed presentation and whether symptoms worsened during this interval, as well as caregiver concern about the child or caregiver having COVID-19 at the time of ED visit., Results: Of 1543 caregivers completing the survey, 287 (18.6%) reported a delay in seeking ED care due to concerns of contracting COVID-19 in the hospital. Of those, 124 (43.2%) stated their child's symptoms worsened during the waiting interval. Caregiver relationship to child [mother] (OR 1.85, 95% CI 1.27-2.76), presence of chronic illness in child (OR 1.78. 95% CI 1.14-2.79), younger age of caregiver (OR 0.965, 95% CI 0.943-0.986), and caregiver concerns about lost work during the pandemic (OR 1.08, 95% CI 1.04-1.12) were independently associated with a COVID-19-related delayed presentation in multivariable regression analysis., Conclusions: Almost one in five caregivers reported delaying ED presentation for their ill or injured child specifically due to fear of contracting COVID-19 while in hospital, with mothers, younger caregivers, caregivers of children with chronic illness, and those concerned about lost work more likely to report delaying ED presentation., (© 2021.

Vaccines against COVID-19 are likely to be approved for children under 12 years in the near future. Understanding vaccine hesitancy in parents is essential for reaching herd immunity. A cross-sectional survey of caregivers in 12 emergency departments (ED) was undertaken in the U.S., Canada, and Israel. We compared reported willingness to vaccinate children against COVID-19 with an initial survey and post-adult COVID-19 vaccine approval. Multivariable logistic regression models were performed for all children and for those <12 years. A total of 1728 and 1041 surveys were completed in phases 1 and 2, respectively. Fewer caregivers planned to vaccinate against COVID-19 in phase 2 (64.5% and 59.7%, respectively; p = 0.002). The most significant positive predictor of willingness to vaccinate against COVID-19 was if the child was vaccinated per recommended local schedules. Fewer caregivers plan to vaccinate their children against COVID-19, despite vaccine approval for adults, compared to what was reported at the peak of the pandemic. Older caregivers who fully vaccinated their children were more likely to adopt vaccinating children. This study can inform target strategy design to implement adherence to a vaccination campaign.

The coronavirus disease 2019 (COVID-19) pandemic has taken an unprecedented global toll and vaccination is needed to restore healthy living. Timely inclusion of children in vaccination trials is critical. We surveyed caregivers of children seeking care in 17 Emergency Departments (ED) across 6 countries during the peak of the pandemic to identify factors associated with intent to participate in COVID-19 vaccine trials. Questions about child and parent characteristics, COVID-19 expressed concerns and parental attitudes toward participation in a trial were asked.Of 2768 completed surveys, 18.4% parents stated they would enroll their child in a clinical trial for a COVID-19 vaccine and 14.4% would agree to a randomized placebo-controlled study. Factors associated with willingness to participate were parents agreeing to enroll in a COVID-19 vaccine trial themselves (Odds Ratio (OR) 32.9, 95% Confidence Interval (CI) (21.9-51.2)) having an older child (OR 1.0 (1.0-1.01)), having children who received all vaccinations based on their country schedule (OR 2.67 (1.35-5.71)) and parents with high school education or lower (OR 1.79 (1.18-2.74)). Mothers were less likely to enroll their child in a trial (OR 0.68 (0.47-0.97)). Only one fifth of families surveyed will consider enrolling their child in a vaccine trial. Parental interest in participation, history of vaccinating their child, and the child being older all are associated with parents allowing their child to participate in a COVID vaccine trial. This information may help decision-makers and researchers shape their strategies for trial design and participation engagement in upcoming COVID19 vaccination trials.

Objectives: To determine factors associated with parents who plan to vaccinate their children against influenza next year, especially those who did not vaccinate against influenza last year using a global survey., Study Design: A survey of caregivers accompanying their children aged 1-19 years old in 17 pediatric emergency departments in 6 countries at the peak of the coronavirus disease 2019 (COVID-19) pandemic. Anonymous online survey included caregiver and child demographic information, vaccination history and future intentions, and concern about the child and caregiver having COVID-19 at the time of emergency department visit., Results: Of 2422 surveys, 1314 (54.2%) caregivers stated they plan to vaccinate their child against influenza next year, an increase of 15.8% from the previous year. Of 1459 caregivers who did not vaccinate their children last year, 418 (28.6%) plan to do so next year. Factors predicting willingness to change and vaccinate included child's up-to-date vaccination status (aOR 2.03, 95% CI 1.29-3.32, P = .003); caregivers' influenza vaccine history (aOR 3.26, 95% CI 2.41-4.40, P < .010), and level of concern their child had COVID-19 (aOR 1.09, 95% CI 1.01-1.17, P = .022)., Conclusions: Changes in risk perception due to COVID-19, and previous vaccination, may serve to influence decision-making among caregivers regarding influenza vaccination in the coming season. To promote influenza vaccination among children, public health programs can leverage this information., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Purpose: This study determined the predictors of caregivers' willingness to accept an accelerated regulatory process for the development of vaccines against coronavirus disease 2019 (COVID-19)., Methods: An international cross-sectional survey was administered to 2557 caregivers of children in 17 pediatric emergency departments (EDs) across 6 countries from March 26, 2020, to June 30, 2020. Caregivers were asked to select 1 of 4 choices with which they most agreed regarding a proposed COVID-19 vaccine-approval process, in addition to questions regarding demographic characteristics, the ED visit, and attitudes about COVID-19. Univariate analyses were conducted using the Mann-Whitney U test for comparing non-normally distributed continuous variables, an independent t test for comparing normally distributed continuous variables, and a χ 2 or Fisher exact test for categorical variables. Multivariate logistic regression analysis was used for determining independent factors associated with caregivers' willingness to accept abridged development of a COVID-19 vaccine. A P value of <0.05 was considered significant., Findings: Almost half (1101/2557; 43%) of caregivers reported that they were willing to accept less rigorous testing and postresearch approval of a new COVID-19 vaccine. Independent factors associated with caregivers' willingness to accept expedited COVID-19 vaccine research included having children who were up to date on the vaccination schedule (odds ratio [OR] = 1.72; 95% CI, 1.29-2.31), caregivers' concern about having had COVID-19 themselves at the time of survey completion in the ED (OR = 1.1; 95% CI, 1.05-1.16), and caregivers' intent to have their children vaccinated against COVID-19 if a vaccine were to become available (OR = 1.84; 95% CI, 1.54-2.21). Compared with fathers, mothers completing the survey were less likely to approve of changes in the vaccine-development process (OR = 0.641; 95% CI, 0.529-0.775)., Implications: Less than half of caregivers in this worldwide sample were willing to accept abbreviated COVID-19 vaccine testing. As a part of an effort to increase acceptance and uptake of a new vaccine, especially in order to protect children, public health strategies and individual providers should understand caregivers' attitudes toward the approval of a vaccine and consult them appropriately., (Copyright © 2020 Elsevier Inc.
