Most cervical cancers are associated with human papillomavirus (HPV), a sexually transmitted infection. Widespread immunization with the HPV vaccine could reduce the impact of cervical cancer worldwide. Here's what you need to know about the HPV vaccine.
What does the HPV vaccine do?
Various strains of HPV spread through sexual contact and are associated with most cases of cervical cancer. Gardasil 9 is an HPV vaccine approved by the U.S. Food and Drug Administration and can be used for both girls and boys.
​
This vaccine can prevent most cases of cervical cancer if given before a girl or woman is exposed to the virus. In addition, this vaccine can prevent vaginal and vulvar cancer in women, and can prevent genital warts and anal cancer in women and men.
​
Certain types of HPV have also been linked to cancers in the mouth and throat, so the HPV vaccine likely offers some protection against these cancers, too.
​
Who is the HPV vaccine for and when should it be given?
The Centers for Disease Control and Prevention (CDC) and The U.S. Food and Drug Administration recommend and approve the use of Gardasil 9 for all females ages 9 to 45.
​
Who should not get the HPV vaccine?
The HPV vaccine isn't recommended for pregnant women or people who are moderately or severely ill. Tell your doctor if you have any severe allergies, including an allergy to yeast or latex. Also, if you've had a life-threatening allergic reaction to any component of the vaccine or to a previous dose of the vaccine, you shouldn't get the vaccine.
​
Does the HPV vaccine offer benefits if you're already sexually active?
Yes. Even if you already have one strain of HPV, you could still benefit from the vaccine because it can protect you from other strains that you don't yet have. However, none of the vaccines can treat an existing HPV infection. The vaccines protect you only from specific strains of HPV you haven't been exposed to already.
​
Does the HPV vaccine carry any health risks or side effects?
Overall, the effects are usually mild. The most common side effects of HPV vaccines include soreness, swelling or redness at the injection site.
Sometimes dizziness or fainting occurs after the injection. Remaining seated for 15 minutes after the injection can reduce the risk of fainting. In addition, headaches, nausea, vomiting, fatigue or weakness also may occur.
​
Do women who've received the HPV vaccine still need to have Pap tests?
Yes. The HPV vaccine isn't intended to replace Pap tests. Routine screening for cervical cancer through regular Pap tests beginning at age 21 remains an essential part of a woman's preventive health care.
