What Is Human Papillomavirus?
Human papillomaviruses (HPV) are a group of more than 100 viruses.
Certain types of HPV can cause genital warts, which are growths or bumps that appear:
HPV is easily spread during oral, genital, or anal sex with an infected partner.
Many people will be exposed to a form of HPV at some point in their lives. Not all will become infected or develop symptoms.

The HPV vaccine contains virus-like particles that are not infectious. These particles produce antibodies to prevent HPV from infecting cells. The vaccine is given by injection into the muscle.
The vaccine protects against 9 types of HPV strains. It may be used to prevent the following conditions:
Who Should Be Vaccinated and When? TOP
The HPV vaccine is recommended for girls and boys between 11-12 years old (2 doses at least 6 months apart). For the vaccine to be most effective, adolescents should complete the series before their first sexual contact in order to have time for an immune response to develop. The vaccine may be given starting at 9 years old.
Other recommendations for the HPV vaccine series include:
A 3-shot series is given in those with a suppressed immune system or if the vaccine is started at age 15 or older.
The vaccine is recommended to children starting at age 9 who have a history of sexual abuse.

Other preventive measures include:
