Adolescents Who Have Undergone Human Papillomavirus Vaccination Are More Likely to Get a COVID-19 Vaccine.

ABSTRACT

PURPOSE: Human papillomavirus (HPV) and COVID-19 vaccination are both recommended for adolescents of ages 12-17. In May 2021, the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices allowed the two vaccines to be administered concurrently. METHODS: We identified adolescents of ages 12-17 using electronic health records from a large integrated delivery system. We assessed associations between socio-demographic characteristics and uptake of HPV vaccination and COVID-19 vaccination, as well as the cumulative proportion of adolescents who obtained a COVID-19 vaccine over time by HPV vaccination status. RESULTS: We identified 40,819 adolescents; 65% had received any COVID-19 vaccination, and 79% had received any HPV vaccination. Adolescents who had initiated HPV vaccination had about 4-fold greater odds of having obtained a COVID-19 vaccine than those who had not (odds ratio = 4.02, 95% confidence interval = 3.81, 4.24). DISCUSSION: Patterns of vaccination uptake suggest possible advantages to co-promotion of adolescent vaccines.
