Came across two studies relevant to concerns over the safety and effectiveness of HPV vaccines this morning.
The first on is an Australian study of the incidence of HPV viruses in girls 18-24 before (2005-2007) and after (2010-2012) HPV vaccines were wide spread in Australia.
They concludes that certain types of HPV virus they tested for were significantly lower int he postvaccine group (6.6% versus 28.7%) and that this applied both to women who had been vaccinated (drop to 5.0% of them having the virus) and those unvaccinated, presumably benefiting from herd immunity (drop to 15.8% of them having the virus in the postvaccination time period sample).
The safety study was done in the US. They looked at hospital admissions in a sample of girls almost 190,000 girls who had have the HPV vaccination. The compared admission in the time period right after the vaccination, and in a time period not related to when they got vaccinated. They found no significant difference in admissions, except a slightly higher incidence of skin infections following vaccination.
Isn't it good to see these studies being done.
