HPV vaccine cut Cervical Cancer rates among women by 87%.The study was published Wednesday in the journal The Lancet.The study estimates that by mid-2019, there were 450 fewer cases of Cervical Cancer and 17,200 fewer cases of pre-cancers than expected in the vaccinated population.
Researchers at Kings College London and the British government looked at population-based cancer registry data in the UK between January 2006 and June 2019 for seven groups of women, comparing those who were vaccinated to those who were not.They were looking at data covering the Cervarix vaccine, which protects against two strains of Cervical Cancer-causing human papillomavirus or HPV. Newer vaccines sold under the Gardasil brand protect against even more strains of cancer-causing viruses.
Of the three groups that were vaccinated, each was vaccinated at different ages. One group was vaccinated at age 12-13, another at 14-16, and another at 16 -18. Those vaccinated at the earliest ages were the most protected. Those who got the shot between the ages of 14 and 16 saw a 62% reduced rate, and rates were reduced by 24% among those vaccinated between 16 and 18.
Dr Kate Soldan from the UK Health the co-author of the study said that this study provides the first direct evidence of the impact of the UK HPV vaccination campaign on Cervical Cancer incidence, showing a large reduction in Cervical Cancer rates in vaccinated cohorts.
