The pre-licensure studies are laughable and I don’t even think we can call them “scientific,” which is both funny and sad at the same time. They lacked proper placebos, adequate controls, and literally no monitoring for long-term side-effects. In some of the studies, the participants in third-world countries didn’t even consent to being used as test subjects. Don’t take my word for it though, read the package inserts and the petitions against Gardasil from the countries who can’t be bought
Sure, you’ll find some post-licensure studies that praise the HPV vaccine, but almost all of them (if not all of them) have been conducted by the manufacturer themselves, an individual who receives funding from them, or they were published by a publication that has Merck in it’s back pocket. The safety and efficacy of Gardasil is nothing short of a joke.
