What to Know About the HPV Vaccine

Nearly 1 in 4 Americans have HPV, a STD that can cause genital warts and cancer. A vaccine is available and recommended for boys and girls ages 11 and up.

What to Know About the HPV Vaccine

Nearly 1 in 4 Americans have human papillomavirus (HPV), a sexually transmitted infection that may cause genital warts and some types of cancer. The good news? There’s a vaccine available to prevent HPV and, in turn, the cancers it causes.

We talked to Gretchen Homan, MD, a pediatrician with Wesley Medical Center in Wichita, to get the facts about the HPV vaccine.


What cancers are caused by HPV?

Basically, all cervical cancers are caused by HPV. In addition, 91% of anal cancers and 72% of oral cancers are caused by HPV. The virus has also been linked to penile, vaginal and vulvar cancers.

Why is the HPV vaccine so important?

We know these cancers are almost always caused by HPV, so if we can provide a vaccine for it, we’re basically getting rid of all these cancers.

Who should get the HPV vaccine?

Boys and girls should get the first of the three-dose vaccine series at age 11 and complete the series within a year. We can vaccinate women up to age 26 and men up to age 21.

What does age have to do with the vaccination?

The vaccine is more effective if we give it earlier—the immune response in the body is stronger when we vaccinate the kids at age 11.

What are the different types of HPV vaccines?

There are three different types of HPV vaccines used to prevent cervical cancer and genital warts:

  • HPV quadrivalent (Gardasil): Until recently, this was the most popular vaccine in the U.S. used to prevent HPV 16, 18, 6 and 11.
  • 9-Valent (Gardasil 9): Most doctors in the U.S. are using this vaccine now as it protects against additional strains of HPV and provides broader coverage.
  • Bivalent (Cervarix): Used mainly on people with an allergy to yeast, the bivalent vaccine prevents HPV 16 and 18, the two strains of the virus responsible for causing 70% of cervical cancers.

How safe is the vaccine?

As of 2014, 67 million doses of the quadrivalent vaccine were given and, of those, only a miniscule number of patients experienced any problems. The most common adverse effect is a local reaction, such as pain or redness at the site of the injection. Some patients may feel lightheaded, so we make sure they’ve had something to eat before the vaccine and that they rest afterwards.

How long does the vaccine protection last?

At this point, there are no recommendations for booster doses of the vaccine after you complete the three-dose series.

Are there any other ways to prevent HPV?

The only other way to prevent HPV would be to never have sexual contact.

Will you ever feel comfortable in your own skin? That is, if you don't make an effort to protect it? Although 64% of adults do report wearing sunscreen when outside for prolonged periods of time, it turns out that only about 10% of people surveyed actually protect themselves daily, according to a recent review.

No matter what your skin tone is, unless you live in a cave with no sunlight, daily protection with either sunscreen, sunblock or protective clothing can not only protect you from developing sunburns (ouch!) but can significantly reduce your risk of developing skin cancer, particularly the deadliest type called melanoma. In addition, for those of you wanting to keep your youthful looks, daily sunscreen has been shown to reduce the development of wrinkles. A great teacher once told me that the best way to not have wrinkles is not to get them in the first place (think of how much money you can save on useless creams that claim to diminish wrinkles).
