A Norwegian study came out this year about the link between HPV and CFS/ME. For those who don't know, there have been some complaints about onset of ME after receiving the vaccine. This study claims, "Girls who have received one or more doses of HPV vaccine have no greater risk of CFS / ME than girls who have not received HPV vaccine." The study: http://www.sciencedirect.com/science/article/pii/S0264410X17308083 Summary (source: solvecfs): I'm hoping to get thoughts on this study, since I'm not able to ingest all of it due to cognitive issues. I personally had sudden onset ME 2 weeks after receiving the Gardasil HPV vaccine and would like to know for sure if it's just a coincidence. My question is: Is this study definitive? Would there be issues with diagnosing ME in the first place, or would that not affect the outcome of the study?
