How effective are the human papillomavirus(HPV) vaccines?

The human papillomavirus (HPV) vaccine works very well. A recent study by the CDC showed that the HPV vaccine is very effective and helped to lower HPV infection rates in teen girls by more than half. Other studies have shown that genital warts (caused by HPV infections) have also decreased in teens since the HPV vaccine came out.

Gardasil and Cervarix are highly effective in preventing infection with the types of human papillomaviruses (HPV) they target. Studies have shown that both Gardasil and Cervarix prevent 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 among women who were not infected at the time of vaccination.

This answer is based on source information from the National Cancer Institute.

Human papillomavirus (HPV) vaccines can be very effective. In a number of studies in women it was shown that 93 to 97 percent of disease from HPV could be prevented by vaccines. HPV vaccination in boys has been shown to reduce HPV spread.
