    Attitudes toward Adolescent HPV Vaccination after the COVID-19 Pandemic: A National Survey of Mothers

    In the United States, vaccination rates for many routinely recommended vaccines have recovered to pre-pandemic levels, yet human papillomavirus (HPV) vaccination rates still lag pre-pandemic levels. This study sought to uncover the potential effects of the pandemic on attitudes about the HPV vaccine, and factors associated with changes in attitudes. We conducted a national survey (n = 3968) of U.S. mothers with children aged 9-17 years. Outcome variables measured changes in attitude toward the HPV vaccine following the pandemic. Two logistic regression models identified predictors of (1) those who did not have attitude changes (always negative vs. always positive), and (2) those who reported attitude changes (change to negative vs. change to positive). Attitudes toward the HPV vaccine remained unchanged in 78.9% of participants (58.1% positive, 20.8% negative). Of the 21.1% reporting changed attitudes, 9.6% changed to positive and 11.5% to negative. Those reporting changing to a negative attitude had a greater odds of reporting conservative political views, and being unsure/undecided about vaccinating their child against HPV compared to those who reported changing to a positive attitude. Targeted strategies are needed to address erosion in confidence in the HPV vaccine and other vaccines resulting from mis- and disinformation associated with the COVID-19 pandemic and future pandemics.

    Characterizing U.S. mothers with high human papillomavirus vaccine intent yet unvaccinated adolescents
    (Elsevier, 2023-04) Srivastava, Tuhina; Head, Katharine J.; O'Dell, Sean; Feemster, Kristen A.; Panozzo, Catherine A.; Zimet, Gregory D.; Kornides, Melanie L.; Communication Studies, School of Liberal Arts
    HPV vaccination rates remain suboptimal in the United States. While the current literature focuses on expressly hesitant parents, few studies have examined parents with “high intent”, or those indicating they definitely will vaccinate and have had the opportunity but not yet vaccinated their adolescents. Our objective was to differentiate characteristics of mothers with high intent from those who already vaccinated their adolescents using various socioeconomic, previous vaccine decision-making, and healthcare provider relationship-related variables. English-speaking mothers or female guardians of adolescents ages 11–14 years living in low HPV vaccine uptake states within the U.S. in September 2018 were recruited from a national survey panel as part of a larger study. We assessed HPV vaccine status of their adolescents and categorized respondents into two categories: Already Vaccinated and High Intent. We assessed differences using a multivariable logistic regression model. Among 2406 mothers, 18% reported high intent vs. 82% already having vaccinated. Mothers with high intent were more likely to identify as non-Hispanic White (p = 0.01), to have a younger adolescent (p < 0.001), and to report not receiving a provider HPV vaccination recommendation (p < 0.001). Mothers who estimated that half/more (vs. less) of their child's friends have received/will receive the vaccine had higher odds of already vaccinating (p < 0.001). Our findings suggest that clinicians may be able to improve HPV vaccination uptake within their practices by giving repeated, high-quality recommendations to parents of children who are not yet vaccinated. Additionally, these findings indicate perceived social norms may play a large role in on-time vaccine uptake. Reassuring hesitant parents that most parents accept the vaccine may also improve uptake in clinical practice.

    Efficacy of tailored messages to improve behavioral intent to accept HPV vaccination among mothers may be moderated by sociodemographics
    (Elsevier, 2021-05-29) Feemster, Kristen A.; Head, Katharine J.; Panozzo, Catherine A.; O'Dell, Sean M.; Zimet, Gregory D.; Kornides, Melanie L.; Pediatrics, School of Medicine
    We assessed differences in response to a tailored recommendation intervention for HPV vaccine by participants’ sociodemographic characteristics in this exploratory sub-analysis of a larger web-based, randomized-controlled trial on tailored messaging among mothers with low intent to vaccinate their 11–14-year-old child against HPV. The intervention consisted of pre-recorded video messages tailored to 1–5 common concerns about HPV vaccine. In these exploratory analyses, we used generalized linear models to assess differences in post-intervention intent across intervention arms, stratified by sociodemographic characteristics among 496 trial participants. We found significantly higher post-intervention intent in the intervention participants versus the control group among mothers: 1) with younger children; 2) with white vs. black children; 3) with Non-Hispanic children; 4) who were younger; 5) with some college or vocational training; with household incomes of ≥$100,000; and 7) with 1–2 children. Our findings of effect modification by certain sociodemographic factors such as age, race/ethnicity, and household income should be considered when designing similar tailored messaging interventions.
