An article published in Pediatrics this month reports that rates of HPV have dropped since vaccination was introduced in the U.S. in 2006, however, a closer look reveals that the decrease only came for the four strains included in the vaccine. There are over 100 serotypes of HPV, many of which can cause cancer.
This study found that although the 4 types of HPV in the vaccine have decreased, the prevalence of HPV infection has actually gone up 3.7%, evidence that the vaccine is causing other strains to take the place of those eliminated through vaccination.
This is a well understood phenomenon called “serotype replacement” that was seen early on in the clinical trial stage of HPV vaccination. The solution consists of either stopping vaccination, or adding more HPV serotypes to the original vaccine.
From the article:
The U.S. HPV vaccination program has not decreased the prevalence of HPV, it has only changed the types of HPV that are infecting the population. The CDC reports that serotypes now on the decline had been the most common prior to introduction of the vaccine, therefore those strains were historically responsible for causing the most cervical cancers. There is a real possibility, however, that the new ‘common’ strains will be even more virulent, leading to an increase in cancer rates over time.
