A recent study from the U.K. has found that the first cohort of women vaccinated against HPV experienced an impressive 87% reduction in cervical cancer cases. The HPV vaccine has been recommended by health authorities since 2006, yet research continues to assess its effectiveness in real-world settings. This new data, published in The Lancet, highlights the significant impact of the vaccine on cervical cancer incidence among women.
Researchers analyzed cancer registry data from June 2006 to June 2019, comparing seven groups of women—those who received the HPV vaccine versus those who did not. The findings indicated that the vaccinated population had 450 fewer cervical cancer cases and 17,200 fewer pre-cancer cases than anticipated.
The study examined various age groups among the vaccinated participants, noting that those who received the vaccine at a younger age benefitted the most. For instance, individuals vaccinated at ages 12-13 exhibited the highest level of protection, while those vaccinated at ages 14-16 and 16-18 showed reductions of 62% and 24%, respectively, in cervical cancer cases.
Encouragingly, this research focused on Cervarix, the initial HPV vaccine that targets only two strains of the virus. The more widely used Gardasil vaccine, which protects against additional strains, is expected to further decrease cancer rates.
Dr. Lila Johnson, one of the study’s authors, remarked, “This research showcases the significant impact of the U.K.’s vaccination program on cervical cancer rates. It is a pivotal advancement in the fight against cervical cancer, and we hope it motivates more people to get vaccinated to ensure the program’s continued success.”
While cervical cancer remains rare among young women, the long-term effects of widespread HPV vaccination are still being evaluated. Experts anticipate even lower cancer rates as more effective vaccines are developed, akin to the transition from Cervarix to Gardasil.
Last year, the World Health Organization set a historic goal to eliminate cervical cancer globally, aiming to vaccinate 90% of girls by age 15.

Summary
A U.K. study reveals that the HPV vaccine has led to an 87% reduction in cervical cancer rates among vaccinated women, with significant disparities based on age at vaccination. This research underscores the importance of vaccination in preventing cervical cancer and aligns with global efforts to eradicate the disease.
