A research group led by Dr. Yusuke Tanaka and Assistant Professor Yutaka Ueda of the Department of Organ Control and Foreign Science, Graduate School of Medicine, Osaka University calculated the effects of suspension of cervical cancer preventive vaccine vaccination and calculated the effects of HPV (human papillomavirus). ) It was clarified that the risk of infection may differ greatly depending on the "year of birth".
The research group has set the risk of infecting Japanese women born between 6 and 7 at the age of 16 for HPV 18/1993, which is thought to be involved in 2008 to 20% of cervical cancer, by year of birth. Calculated in.As a result, it was clarified that every year after the resumption of vaccination recommendation is delayed, a population with a significantly high infection rate is generated, and the risk of HPV infection may vary greatly depending on the year of birth.
The cervical cancer preventive vaccine was subsidized by the public in Japan in 2010, and regular vaccination for 2013 to 4 years old started in April 12. The recommendation has been suspended since June 16, and as a result, there is a big difference in the vaccination rate depending on the year of birth.
The results of this study revealed that it is desirable to resume vaccination recommendations during FY2016 in order to minimize the disparity in future HPV infection risk due to different birth years.If the recommendation by the Ministry of Health, Labor and Welfare will be resumed after 2017, the risk of infection can be suppressed and the impact can be minimized by including women who were 12 to 16 years old during the recommendation suspension period. It is said that there is sex.
The research results were published in the July 2016 issue of the English medical journal "The Lancet Oncology" (online version on June 7).
