Home > Health Library > HPV (Human Papillomavirus) Vaccine Gardasil®: What You Need to Know
Genital human papillomavirus (HPV) is the most common sexually transmitted virus in the United States. More than half of sexually active men and women are infected with HPV at some time in their lives.
About 20 million Americans are currently infected, and about 6 million more get infected each year. HPV is usually spread through sexual contact.
Most HPV infections don't cause any symptoms, and go away on their own. But HPV can cause cervical cancer in women. Cervical cancer is the 2nd leading cause of cancer deaths among women around the world. In the United States, about 12,000 women get cervical cancer every year and about 4,000 are expected to die from it.
HPV is also associated with several less common cancers, such as vaginal and vulvar cancers in women, and anal and oropharyngeal (back of the throat, including base of tongue and tonsils) cancers in both men and women. HPV can also cause genital warts and warts in the throat.
There is no cure for HPV infection, but some of the problems it causes can be treated.
The HPV vaccine you are getting is one of two vaccines that can be given to prevent HPV. It may be given to both males and females.
This vaccine can prevent most cases of cervical cancer in females, if it is given before exposure to the virus. In addition, it can prevent vaginal and vulvar cancer in females, and genital warts and anal cancer in both males and females.
Protection from HPV vaccine is expected to be long-lasting. But vaccination is not a substitute for cervical cancer screening. Women should still get regular Pap tests.
Additional (booster) doses are not recommended.
Why is HPV vaccine recommended at 11 or 12 years of age?
HPV infection is easily acquired, even with only one sex partner. That is why it is important to get HPV vaccine before any sexual contact takes place. Also, response to the vaccine is better at this age than at older ages.
This vaccine is recommended for the following people who have not completed the 3-dose series:
This vaccine may be given to men 22 through 26 years of age who have not completed the 3-dose series.
It is recommended for men through age 26 who have sex with men or whose immune system is weakened because of HIV infection, other illness, or medications.
HPV vaccine may be given at the same time as other vaccines.
This HPV vaccine has been used in the U.S. and around the world for about six years and has been very safe.
However, any medicine could possibly cause a serious problem, such as a severe allergic reaction. The risk of any vaccine causing a serious injury, or death, is extremely small.
Life-threatening allergic reactions from vaccines are very rare. If they do occur, it would be within a few minutes to a few hours after the vaccination.
Several mild to moderate problems are known to occur with this HPV vaccine. These do not last long and go away on their own.
Like all vaccines, HPV vaccines will continue to be monitored for unusual or severe problems.
Signs of a severe allergic reaction can include hives, swelling of the face and throat, difficulty breathing, a fast heartbeat, dizziness, and weakness. These would start a few minutes to a few hours after the vaccination.
VAERS is only for reporting reactions. They do not give medical advice.
The National Vaccine Injury Compensation Program (VICP) is a federal program that was created to compensate people who may have been injured by certain vaccines.
Persons who believe they may have been injured by a vaccine can learn about the program and about filing a claim by calling 1-800-338-2382 or visiting the VICP website at www.hrsa.gov/vaccinecompensation.
