Gardasil is a vaccine that helps protect against 4 types of human papillomavirus (HPV) that cause cervical cancer and genital warts. It was given around 2.2 million doses of the vaccine in 2006 and 11.3 million in 2007 in the US.
The CDC's Vaccine Adverse Event Reporting System (VAERS) reported there were as much as 7,802 cases of people reporting about adverse reactions to the vaccine during the period between June 8, 2006 and April 30, 2008. They ranged from the minor pain in the place of injection to serious side effects. As much as 31 vaccine recipients reported about Guillain-Barré syndrome, an acute condition affecting nervous system that usually exhibits as a total body paralysis.
There were also 15 cases of death reported after vaccine. However, specialists analyzing the reports could not find the relationship between the vaccine and the deaths.
Gardasil vaccine was tested in over 11,000 females in the US. There were 10 cases of death reported in a group, who received the vaccine and 7 cases of death in the placebo group. The cases were considered unrelated to the vaccination.
HPV is considered to be one of the most common sexually transmitted infections in the United States. It is estimated that around 11,070 women will contract the sexually transmitted virus and almost 3,870 women die of cervical cancer.
