Background: Human papillomavirus (HPV) is the most common sexually transmitted infection in the US.The first HPV vaccine was introduced in 2006. There are three different HPV vaccines that commonly target high-risk HPV types.

Objective: This study compares HPV vaccine efficacy based on alternative endpoints with the most recently available cervical cancer incidence data from the Surveillance, Epidemiology and End Results (SEER) program and SEER*Stat statistical software.

Methods: The incidence of cervical cancer, mined from the most recent April 2021 SEER data set, was stratified according to age and racial groups. Trend analysis reporting cervical cancer incidence percentage change (PC) and annual percentage change (APC) was calculated by SEER*Stat statistical software.

Results: A total of 46,583 cases of cervical cancer were reported, with an average of about 3,580 incidents of cervical cancer per year, with an overall decrement of about 60 cases over the period of 12 years. The percentage change according to age and race groups varied between -15.9 among 40- 44 years old (yo) and +13.8 among 30-34 yo, and from -12 among non-Hispanic White women to +13 among Hispanic women. Statistically significant APC was observed for five of the nine age groups and four of the five racial groups.

Conclusion: There seems to be little if any, correlation between cervical cancer incidence and the HPV vaccine program in the US. HPV vaccine efficacy based on alternative endpoints, such as nucleic acid testing and cytological, surgical, and seropositivity endpoints, is fair. Therefore, it is important to emphasize such alternative testing and surrogate endpoints.

Keywords: Human papillomavirus, cervical cancer, vaccine efficacy, cancer incidence, SEER, alternative endpoints, sexually transmitted infection.
