Impact of a human papillomavirus vaccination clinical program in a commercially insured population

The difference observed between cohorts for the proportion of members who completed the series was not statistically significant. Cohorts B and C completed the series later compared with Cohort A, and a higher proportion received doses 1 and 2 more than 1 year apart. Although the years 2020 and 2021 were not included, lasting impact from the pandemic may have influenced study results; however, BCBSM's efforts may have mitigated the impact of the national decrease seen in HPV vaccination among in-state members.
