Shared Determinants for Human Papillomavirus and COVID-19 Vaccination Intention: An Opportunity for Resource Consolidation.

PURPOSE

This study aimed at targeting shared factors that influence the prevention of multiple diseases, which can help address various health problems simultaneously. We identified correlates of human papillomavirus (HPV) vaccination that overlap with COVID-19 vaccination.

DESIGN

Cross-sectional survey data.

SETTING

Online Qualtrics recruitment panel.

SUBJECT

Religious parents of 342 adolescents who were unvaccinated for HPV (response rate was 68.1%).

MEASURES

Outcome variables were COVID-19 vaccination intention for (1) self, (2) child, and (3) HPV vaccination intention for child. Independent variables were psychological factors. Covariates were sociodemographic and socioeconomic factors.

ANALYSIS

We conducted multivariate linear regressions on each outcome variable after controlling for covariates.

RESULT

Some psychological correlates of HPV overlapped as protective factors for all three outcomes. Higher perceived vulnerability of child to HPV was associated with higher vaccination intention against COVID-19 for self (β = .37, 95% confidence interval [CI] = .25-.48), child (β = .32, .21-.44), and HPV for child (β = .38, .27-.49). Higher perceived response efficacy of HPV vaccine was associated with greater vaccination intention against COVID-19 for self (β = .46, .33-.59), child (β = .41, .28-.53), and HPV for child (β = .75, .64-.85).

CONCLUSION

Given the overlap in HPV and COVID-19 vaccination correlates, interventions should target shared factors that address both diseases to maximize public health efforts. A major limitation of this study is the inability to measure the actual vaccination behavior.
