The FDA and the CDC consider the vaccine to be safe.
It does not contain mercury, thiomersal or live virus or dead virus, only virus-like particles, which cannot reproduce in the human body.
Each woman was injected with either Gardasil or a placebo on Day 1, Month 2, and Month 6.In total, 6,082 women were given Gardasil and 6,075 received the placebo.These VLPs were the basis for the HPV16 component of the Gardasil vaccine.The history of the discovery of this vaccine is described by Mc Neil. conducted a Phase III study named Females United to Unilaterally Reduce Endo/Ectocervical Disease (FUTURE II).The National Cancer Institute says, "FDA-approved Gardasil prevented nearly 100 percent of the precancerous cervical cell changes caused by the types of HPV targeted by the vaccine for up to 4 years after vaccination." The vaccine is believed to be effective for longer, but for how long, and whether a booster shot will be needed is still being studied.
Darren Brown of Indiana University, reported at the 2007 Interscience Conference on Antimicrobial Agents and Chemotherapy that Gardasil had 38% efficacy against 10 other HPV types responsible for The Food and Drug Administration and the Centers for Disease Control and Prevention say that the vaccine has only minor side effects, such as soreness around the injection area.
HPV types 6 and 11 cause about 90% of genital warts cases. The research that led to the development of the vaccine began in the 1980s by groups at the University of Rochester, Georgetown University, and the US National Cancer Institute (NCI).
In 1993, a laboratory at the US National Cancer Institute was able to generate HPV16 VLPs that were morphologically correct.
Many state legislators have penned bills that do this.
Almost all pieces of legislation currently pending in the states that would make the vaccine mandatory for school entrance have an "opt-out" policy.
