A study published in the Journal of the National Cancer Institute found that the vaccine Cervarix effectively protected women from cervical cancer when administered between ages 12 and 13. Data was collected from 447,845 women in Scotland, with no cases of cervical cancer found among those vaccinated at ages 12-13, regardless of the number of doses received. Women vaccinated between ages 14-18 with three doses had fewer instances of cervical cancer compared to unvaccinated women. Ongoing monitoring is needed to assess the effects of changes in vaccines and dosage schedules since the start of vaccination in Scotland. The study was funded by Public Health Scotland and some authors reported previous advisory board meetings and research funding from various companies.
