Vaccines for Adults: What You Should Know

Vaccines for Adults: What You Should Know


In 2006 when the FDA approved the first human papillomavirus (HPV) vaccine, it was big news. The new HPV vaccination made headlines at the time, which wasn’t surprising considering that it was the very first vaccine approved to prevent cancer — cervical cancer, to be exact.

Even though the HPV vaccine have now been around for a few years, not everyone knows exactly what it is, or what it does. You might be wondering: How does it work? Is it safe? Should you or your child get it?

So you can be more confident when you talk to your doctor about the HPV vaccine, here are answers to these and other common questions about the vaccine.
What Is HPV?

HPV stands for human papillomavirus. It’s a virus that can be transmitted through sexual contact. During intercourse or oral sex, HPV can make its way into the genitals, mouth, or throat and cause infection.

Sexually transmitted HPV comes in more than 40 different varieties. The type of the virus you get determines what effects it has on your body. Certain types of HPV cause genital warts. Other HPV types can make cells turn cancerous. You’ve probably heard that HPV causes cervical cancer, but it also causes less common cancers of the vulva, vagina, penis, anus, head, and neck.

What’s tricky about HPV is that it doesn’t have symptoms. There’s no sore throat or fever to let you know you’ve been infected. Most people clear the infection on their own. In fact, you might have absolutely no idea you’ve been infected until you develop genital warts or have an abnormal Pap test.

Though HPV might not be as well known among sexually transmitted infections (STIs) as herpes or syphilis, it is actually the most common STI. If you’re sexually active, you’ve got about a 50/50 chance of being infected with HPV at some point in your life. That’s why immunization is so important.
There are two HPV vaccines; what’s the difference?

Two vaccines are available to protect females against the types of HPV that cause most cervical cancers. One of these vaccines also protects men and women against most genital warts. Whichever of these vaccines you and your doctor choose, you should stick with the same vaccine for all three shots.
Do I have to get the HPV vaccine?

The HPV vaccine is an important way for women to protect themselves against cervical cancer, which kills about 4,000 women each year in the U.S. It can also protect both men and women against genital warts. However, vaccination doesn’t protect against all HPV types that cause cervical cancers or genital warts. Whether you have to get vaccinated depends on your age and where you live. In certain states, girls within the recommended ages may need to get the HPV vaccine in order to go to school.

When should I get the HPV immunization?

The best time to get the HPV vaccine is before you’ve started having sexual activity. That’s why the CDC recommends that girls get their vaccination at age 11 or 12, although they can get the vaccine as early as age 9. If you’re 13 or older and you haven’t already been vaccinated, you can still get the vaccine up to age 26.

Although HPV vaccination is not on the recommended immunization schedules for boys and young men, they can get the Gardasil vaccine between ages 9 and 26 to protect them against genital warts.
If I’m over age 26, can I still get vaccinated?

The HPV vaccine isn’t recommended for people over age 26, because it hasn’t been studied well enough in this age group. If enough future studies show that it is safe and effective for people over 26, the FDA may eventually start recommending it for this age group.
How many shots do I need?

You’ll get three shots of the HPV vaccine over a 6-month period. You need to take all three doses to be completely protected. You’ll get the second shot about 1 to 2 months after the first, and the third shot 6 months after the first. Once you’ve started with a vaccine brand (Cervarix or Gardasil), stick with it for all three shots.
If I already have HPV, will this vaccine treat it?

No. If you have a current HPV, the vaccine won’t get rid of the infection. However, if you have one type of HPV the vaccine may prevent you from getting another type of the virus. There’s really no way to treat the virus once you have it, although there are treatments for diseases caused by HPV such as genital warts and genital cancers. This is why you should have regular pelvic exams and Pap tests (if you’re female) to screen for cervical cancer.
Does the HPV vaccine protect me for life?

You should be protected against HPV for at least 5 years; that’s how long the vaccine has been tested to work in studies. Longer-term research is needed to confirm exactly how much longer the protection lasts. Even women who are protected against HPV with the vaccine should see their gynecologist regularly for a Pap test to check for cervical cancer since the vaccine doesn’t protect against all HPV types that can cause cervical cancer.
Will my insurance cover the cost of the HPV vaccine?

Most insurance plans cover recommended vaccines, which means that if you’re a girl or woman ages 11 to 26, your insurance should pay for the vaccine. Check with your insurance company just to be sure. If your family doesn’t have health insurance or you’re on Medicaid, you should be able to get the HPV vaccine for free through the Vaccines for Children (VFC) program.

Is this vaccination safe?

Vaccines have to be rigorously tested before they can be widely distributed. Both HPV vaccines were tested on thousands of people and shown to be safe before they were released to the public. These vaccines have been used for several years now, and experts say the chance of them causing a serious reaction is very slim. You don’t need to worry about mercury or thimerosal with the HPV vaccine, either. It doesn’t contain these preservatives.
Is there any reason why I shouldn’t get this vaccine?

Some people shouldn’t get the vaccine. You definitely don’t want to get the HPV vaccine if you’ve had a serious allergic reaction to it or to any of its components, including baker’s yeast and latex. Let your doctor know if you have any severe allergies. Also talk to your doctor if you have an immune system problem or blood disorder.

If you’re pregnant, you’ll want to wait to get the HPV vaccine until after your baby is born. In studies, HPV vaccines didn’t cause any problems in babies whose mothers got the vaccine while pregnant, but pregnant women should not get HPV vaccine as safety studies are still ongoing.
Could I have side effects from the HPV vaccine?

You could have side effects, but if you do they should be mild. Most people who complain of symptoms after getting the HPV shot have minor issues like pain or swelling at the site of the shot, fever, headache, nausea, vomiting, diarrhea, abdominal pain, or muscle and joint pain.

Sometimes people faint after getting the HPV vaccine or any other vaccination. Sitting down after getting the shot can prevent you from passing out.
If I get the HPV vaccine, is there a chance I could get HPV?

No. The part of the HPV virus used in both vaccines is inactivated (not live) so it can’t cause actual HPV infection.
