A Single Dose of HPV Vaccine Could Prevent Cervical Disease

A single dose of human papillomavirus (HPV) vaccine is associated with significant reductions in the risk of cervical disease, according to the results of a recent study.

“Human papillomavirus (HPV)–related disease remains a significant source of morbidity and mortality, and this underscores the need to increase HPV vaccination to reduce the burden of the disease,” the authors wrote.

They conducted a retrospective matched cohort study using administrative data from Optum’s Clinformatics DataMart Database, identifying 66,541 vaccinated and 66,541 unvaccinated female patients aged 9 to 26 years who had received 1 or more doses of the quadrivalent HPV vaccine between January 2006 and June 2015.

Overall, in participants aged 15 to 19 years, the estimated rate of cervical disease after 5 years of follow-up was 2.65% in the unvaccinated group and 1.62%, 1.99%, and 1.86% in those that received 1, 2, or 3 doses of the HPV vaccine, respectively.

HRs for confirmed cervical disease were 0.64 (95% CI, 0.47‐0.88), 0.72 (95% CI, 0.54‐0.95), and 0.66 (95% CI, 0.55‐0.80) for 1, 2, and 3 doses, respectively.

“The receipt of 1, 2, or 3 doses of an HPV vaccine by females aged 15 to 19 years was associated with a lower incidence of preinvasive cervical disease in comparison with unvaccinated females, and this supports the use of any HPV vaccination in reducing the burden of the disease,” the researchers concluded.
