What went wrong with Gardasil sales? | LifeSiteNews.com: Gardasil’s flat and declining sales are due to a design flaw. To be completely immunized, women and girls have to receive a series of three injections over six months. Many women and girls didn’t do so. For example, according to the U.S. Center for Disease Control, in their report of August 2010, although 44% of teenagers had received the HPV vaccine in 2009, only 27% of them received all three doses of the vaccine. There is no evidence to support the possibility that only one injection effectively protects against cervical cancer.
