Almost 8,000 U.S. recipients of the vaccine used to protect against cervical cancer have reported adverse reactions to it, says the U.S. Centers for Disease Control and Prevention.
A total of 7,802 people who received Gardasil, made by Merck and Co. Inc., have reported adverse events to the CDC’s Vaccine Adverse Event Reporting System (VAERS) between June 8, 2006, and April 30, 2008.
Seven per cent of these were serious side effects, which, according to a recent CDC report, is “about half” the average of vaccines overall. There were 31 reported cases of Guillain-BarrÃƒÆ’Ã‚Â© syndrome (GBS), a neurological condition that results in temporary but often total body paralysis, with 10 cases confirmed.
Fifteen deaths were also reported, with 10 of these containing the level of information required for further analysis, according to the CDC.
“After careful review of those reports, we could not establish the causal relationship between vaccination and death,” reads the VAERS report.
The report notes that when Gardasil was being tested in the U.S. before being licensed, 10 individuals who were in the group that received the vaccine died, and seven in the placebo group died. None of these deaths were considered vaccine-related.
The CDC report points out that most common side effect of the injection is site pain.
The U.S. distributed a total of 2.2 million doses of the vaccine in 2006 and 11.3 million in 2007.
Health Canada approved Gardasil on July 18, 2006. As of Jan. 8, 2008, The Public Health Agency of Canada had received a total of 145 reports of adverse events following vaccination with Gardasil, none of which were of death or GBS, according to the agency.
“These reports are mostly of minor adverse events, including injection site reactions, which are consistent with the results reported by clinical trials conducted prior to the approval of the vaccine, and can be expected with the administration of any vaccine,” reads PHAC’s website.
The vaccine works by boosting the immune system so that it effectively fights off four types of human papillomavirus, the most prevalent STD in modern society. In North America, HPV is said to infect half of all sexually active women between 18 and 22.
