This video defines Human Papillomavirus (HPV), a common sexually transmitted disease that often does not show symptoms, and describes how HPV is transmitted. It states that many types of HPV and most will go away on their own within two years, but In some cases, HPV can cause genital warts, and a few specific types of HPV can increase someone’s risk for cancer.The video also describes the HPV vaccine, which is safe and effective and can protect against almost 100% of types of HPV. The HPV vaccine is most effective if given before someone has sex, but if you’ve already had sex, the vaccine can still be very effective. The video suggests asking your parents or guardian if you’re not sure if you’ve gotten the vaccine, and that it’s still a good idea to use condoms even if you’ve gotten the vaccine to protect against pregnancy and other STDs.
