Vaccine works best when given to girls before they begin having sex and run the risk of HPV infection.

Gardasil, built by Merck & Co. Inc., is protected from the two types of HPV responsible for roughly 70 percent for the cervical cases for cancer.

The vaccine also blocks the infection by two other constraints responsible for 90 percent of genital cases of wart. The clinical trials proved that Gardasil prevented 100 percent of cervical cancer related to the two constraints of HPV among the women who had not been previously infected, Merck known under the name of.

One counts rather than Merck launches Gardasil like cancer, than a STD, vaccine. There does not remain very clear how to be widespread the use of the trois-a drawn from the series, partly because of its current price running $360. The opposition of safeguarding to make the vaccine obligatory to inform can also limit its adoption.

The age of the target to receive Gardasil is low because the vaccine works better once given the girls before they start to have the sex and to run the risk of infection of HPV. The vaccine cannot be protected from the already infected people and can increase their risk as the lesions which can lead to cervical cancer.
