    Factors impacting parental uptake of COVID-19 vaccination for U.S. Children ages 5-17
    (Elsevier, 2023) Harris, Julen N.; Mauro, Christine M.; Morgan, Tucker L.; de Roche, Ariel; Zimet, Gregory D.; Rosenthal, Susan L.; Pediatrics, School of Medicine
    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.

    Understanding factors that influence those who are initially COVID-19 vaccine hesitant to accept vaccination is valuable for the development of vaccine promotion strategies. Using Ipsos KnowledgePanel®, we conducted a national survey of adults aged 18 and older in the United States. We created a questionnaire to examine factors associated with COVID-19 vaccine uptake over a longitudinal period ("Wave 1" in April 2021 and "Wave 2" in February 2022), and utilized weighted data provided by Ipsos to make the data nationally representative. Overall, 1189 individuals participated in the Wave 1 survey, and 843 participants completed the Wave 2 survey (71.6% retention rate). Those who intended to be vaccinated as soon as possible ("ASAP") were overwhelmingly vaccinated by Wave 2 (96%, 95% CI: 92% to 100%). Of those who initially wished to delay vaccination until there was more experience with it ("Wait and See"), 57% (95% CI: 47% to 67%) were vaccinated at Wave 2. Within the "Wait and See" cohort, those with income <$50,000 and those who had never received the influenza vaccine were significantly less likely to be vaccinated at Wave 2. Among those who initially indicated that they would not receive a COVID-19 vaccine ("Non-Acceptors"), 28% (95% CI: 21% to 36%) were vaccinated at Wave 2. Those who believed COVID-19 was not a major problem in their community were significantly less likely to be vaccinated, while those with more favorable attitudes toward vaccines in general and public health strategies to decrease the impact of COVID-19 were significantly more likely to be vaccinated. Overall, barriers to vaccine uptake for the "Wait and See" cohort appear to be more practical, whereas barriers for the "Non-Acceptor" cohort seem to be more ideological. These findings will help target interventions to improve uptake of COVID-19 boosters and future novel vaccines.

    U.S. pregnant women's knowledge and attitudes about behavioral strategies and vaccines to prevent Zika acquisition
    (Elsevier, 2018-01-02) Fraiz, Lauren Dapena; de Roche, Ariel; Mauro, Christine; Catallozzi, Marina; Zimet, Gregory D.; Shapiro, Gilla K.; Rosenthal, Susan L.; Pediatrics, School of Medicine
    INTRODUCTION: Zika virus infection during pregnancy can cause significant infant morbidity. Little is known about pregnant women's attitudes regarding behavioral strategies and hypothetical vaccination to prevent Zika infections and sequelae. METHODS: Pregnant women across the United States (N = 362) completed an online questionnaire regarding attitudes about Zika, including six behavioral prevention strategies (i.e., abstaining from sex, using condoms, not traveling to an area with Zika, their partner not traveling into an area with Zika, using mosquito repellant, wearing long pants and sleeves) and vaccination. RESULTS: Most women (91%) were married/living with the baby's father, 65% were non-Hispanic White, and 71% had been pregnant. Seventy-four percent were worried about Zika, while 30% thought they were knowledgeable about Zika. The mean knowledge score was 5.0 out of 8 (SD = 2.09), and the mean behavioral strategies score was 4.9 out of 12 (SD = 3.7) with a range of 0 (none would be hard to do) to 12 (all would be hard to do). In a multivariable model, having had a sexually transmitted infection, living/traveling in an area with Zika, and worrying about Zika were significantly related to reporting behavioral strategies as hard to do. Seventy-two percent would be willing to be vaccinated. In the multivariable model, living/traveling in an area with Zika, believing they knew a lot about Zika, worrying about Zika, and considering Zika vaccine development as important were significantly associated with willingness to get vaccinated. CONCLUSIONS: Pregnant women were worried about Zika, yet had gaps in their factual knowledge. Most women reported they would get vaccinated if a vaccine was available. Pregnant women who reported themselves as vulnerable (being worried, having lived in or traveled to a Zika area) were more likely to view behavioral strategies as hard to do and to accept vaccination.
