Gardasil may have played a role in two fatal cases of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, according to researchers from the ALS Center at the University of California San Francisco Medical Center. According to WebMD, the researchers looking into the cases can't confirm a connection, but are hoping that by raising awareness, they will learn of any other incidents of ALS that have followed Gardasil vaccination.
Gardasil prevents four strains of HPV, two of which cause 70 percent of all cervical cancers. The other two HPV strains are responsible for about 90 percent of genital warts. However, Gardasil has been the subject of controversy ever since it was approved in 2006. As of June 2009, 15 million girls had received Gardasil, with more than 14,000 recipients reporting adverse reactions. The complaints included reports of dizziness numbness, and blood clots. Health regulators are also looking at 43 reports of fatalities that occurred following Gardasil administration.
