HPV Vaccination for the Prevention of Cervical Cancer Reduced Cervical Cancer by 88%

A Swedish research group has reported that the vaccination for human papillomavirus (HPV) significantly reduced cervical cancer. This study was published in the New England Journal of Medicine, a leading academic journal, on October 1, 2020.
In Sweden, HPV vaccination was started for 13-17 year old girls in 2007. From 2012, regular vaccination (school vaccination) started for 10-12 year old girls and free vaccination for 13-18 year old girls who wish it. This research group analyzed the incidence of cervical cancer in women aged 10-30 years using the data on the number of cancer incidence in Sweden over ten years from 2006 to 2017.
Assuming the incidence of cervical cancer in women who did not receive HPV vaccine as 1, the incidence of cervical cancer in women who received HPV vaccine before the age of 17 was "0.12", which corresponds to 88% decrease. The incidence of cervical cancer in the women vaccinated at the age of 17-30 years was "0.47", which is 53% decrease.
A body of results have been reported on the effectiveness of HPV vaccine from Japan and overseas. They demonstrated the effects of HPV vaccine in reducing precancerous lesions of cervical cancer. The results in the study introduced herein scientifically demonstrated that cervical cancer itself, which affects life and death and often requires total hysterectomy, can be drastically reduced with HPV vaccine.

Based on these scientific grounds, our society strongly recommends you to receive HPV vaccination to prevent cervical cancer.
