HPV vaccine helps protects against a virus that causes several cancers that can affect anyone. These include cancers of the cervix, vulva, vagina and anus in women, or cancers of the anus and penis in men, and possibly throat cancers for both men and women. The vaccine is also effective at preventing genital warts.
- The vaccine works by causing your body’s immune system to produce its own protection (antibodies) against the HPV types most likely to cause cancer or genital warts.
- If an immunised person comes into contact with HPV, the antibodies in their blood will fight the virus and protect them against being infected.
- It usually takes several weeks after vaccination to develop protection against HPV.
Protection from the vaccine is long-lasting and is not expected to wear off over time.
