What is human papillomavirus (HPV) 9-valent vaccine?

Human papillomavirus (HPV) is a sexually transmitted disease that can cause genital warts. HPV can also cause anal cancer or various cancers of the cervix, vagina, vulva, oropharynx (the middle part of the throat), or head and neck.

HPV 9-valent vaccine is used in children and adults ages 9 through 45 years to prevent genital warts or cancers caused by certain types of HPV.

You may receive this vaccine even if you have already had genital warts, or had a positive HPV test or abnormal pap smear in the past. However, this vaccine will not treat active genital warts or HPV-related cancers, and it will not cure HPV infection.

HPV 9-valent vaccine prevents diseases caused only by HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58. It will not prevent diseases caused by other types of HPV.

The Centers for Disease Control and Prevention (CDC) recommends HPV vaccine for all boys and girls ages 11 or 12 years old. The vaccine is also recommended in teenage boys and girls who have not already received the vaccine or have not completed all booster shots.

Like any vaccine, the HPV 9-valent vaccine may not provide protection from disease in every person.

HPV 9-valent vaccine may also be used for other purposes not listed in this medication guide.

HPV 9-valent vaccine side effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Keep track of any and all side effects you have after receiving this vaccine. When you receive a booster dose, you will need to tell the doctor if the previous shot caused any side effects.

You may feel faint after receiving this vaccine. Some people have had seizure like reactions after receiving this vaccine. Your doctor may want you to remain under observation during the first 15 minutes after the injection.

Developing cancer from HPV is much more dangerous to your health than receiving the vaccine to protect against it. However, like any medicine, this vaccine can cause side effects but the risk of serious side effects is extremely low.

Common side effects of human papillomavirus (HPV) vaccine, 9-valent may include:

• pain, swelling, redness, itching, bruising, bleeding, and a lump where the shot was given;

• nausea, diarrhea, stomach pain;

• headache;

• fever;

• sore throat;

• dizziness; or

• tiredness.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1-800-822-7967.
