HPV Vaccine:
A Guide for Parents
There is a new vaccine that helps prevent cervical cancer and other conditions caused by certain types of the Human Papillomavirus (HPV). It is recommended for girls and young women between the ages of 9-26. We hope this guide will answer your questions so you can have a better understanding of the benefits of this vaccine.
What is HPV?
There are many different types of HPV (Human Papillomavirus). There are about 100 different types and more than 30 are sexually transmitted. Researchers keep track of the different types of HPV by identifying them with numbers such as 6, 11,16 and 18.
Some types cause genital warts (flesh colored growths that may appear around the vagina or anus), others cause pre-cancerous changes (cellular changes that can lead to cancer of the cervix later). In rare cases, the virus can cause other types of cancers to the vulva, vagina, anus in girls and the anus and penis in males. (Click here for a drawing of female anatomy).
Is my daughter at risk of getting HPV?
If your daughter is or plans to be sexually active in her lifetime, she is at risk for getting HPV. Any sexually active person—no matter what color, race, gender, or sexual orientation—can get HPV. In fact, at least 1 in every 2 sexually active young women has had a genital HPV infection.
About 6 million new cases of genital HPV are diagnosed in the United States each year. Of this number, it is estimated that 74% of them occur in 15-24 year olds. |
Some people who have been infected with the HPV virus know they have it because they have had genital warts or an abnormal Pap test, or have tested positive for HPV. However, most people do not know they have HPV because they do not have symptoms.
How is HPV spread?
HPV and genital warts are usually spread by direct skin-to-skin contact during vaginal, anal, or oral sex with someone who is infected with HPV. Condoms can help protect against HPV but they aren’t perfect because warts can be found on skin that isn’t covered by a condom. HPV can be in the skin and genital organs without any symptoms. In fact, the only way that is 100% effective in preventing exposure to HPV is avoiding sexual activity that involves contact with genital areas.
What is the HPV vaccine?
There is a new vaccine called Gardasil that protects young women against four different types of HPV (Human Papillomavirus). The vaccine works to prevent two types of HPV—16 and 18, which causes 70% of cervical cancer—and two other types—6 and 11, which cause 90% of genital warts. The vaccine works best in girls/young women who have not yet come in contact with these viruses. That is why the vaccine is recommended for all 11 and 12 year girls as a routine vaccination and for all young women 13-26 years of age who have not yet received the vaccine. Similar to other vaccines, the HPV vaccine is given in a series of 3 shots over 6 months. The first shot is given at any time. The second shot should be given two months after the first shot, and the third shot should be given about six months after the first one.
How does the HPV vaccine work?
The vaccine is a fluid that has very small particles in it that look like HPV. After the vaccine is administered, the body quickly starts making antibodies against the four types of HPV. Antibodies are necessary to fight HPV. Remember the virus is not a live virus, which means your daughter can’t get HPV from the vaccine.
How does a vaccine get approved?
Before the Food and Drug Administration (FDA) approves any medicine or vaccine, scientists and doctors must study it. After researching the vaccine for a long time, the pharmaceutical company must show that the vaccine will improve the health of people who receive it. In June of 2006, the FDA found the HPV vaccine to be an excellent way to lower the chances of getting HPV for girls and young women between the ages of 9-26.
Is the HPV vaccine effective?
When tested in girls, the current HPV vaccine (Gardasil) was 100% effective in preventing pre-cancerous changes in the cervix caused by HPV types 16 and 18. The HPV vaccine was also shown to be nearly 100% effective in preventing vulvar and vaginal pre-cancers and genital warts caused by HPV types 6 and 11. The vaccine is less effective in young women who have already come in contact with HPV (6, 11,16 or 18). However, if a young woman has been exposed only to type 6, the vaccine still gives protection against 11, 16, and 18. So, even young women who have had sexual contact should get immunized.
It is important for your daughter to plan on returning to her health care provider for the second and third shots. |
When is the best time for my daughter to get vaccinated?
The best time for your daughter to get vaccinated is before she comes in contact with the HPV virus. In fact, the government organization that decides when children and adolescents should be immunized recommends that all 11 and 12 year old girls receive it. Health care providers can also offer the vaccine to younger girls (9 and 10 year olds). The vaccine is approved for young women from 9 years of age up to 26 years.
Are there any side effects with the HPV vaccine?
Side effects are rare; however, some young women who get the vaccine may complain of pain, or have swelling, redness, or itchiness where they got the shot (arm or thigh). These discomforts are temporary but may last a couple of days. In very few cases, side effects may include a fever, dizziness, and/or nausea.
Does my daughter have a choice about getting the HPV vaccine?
Some states are planning to make HPV vaccine a requirement; others leave the choice to each family and teen. However, most health care providers will suggest the vaccine if your daughter is between the ages of 9-26 to reduce her risk of cervical cancer.
How do I know if my daughter should get the HPV vaccine?
Talk it over with your daughter’s health care provider. Now that the vaccine is available, it is a good idea to take advantage of it. Most young women will become sexually active at some point in their lives, and the vaccine is very effective in preventing the spread of HPV. The risk of getting HPV is far worse than getting a shot.
Is there any reason why my daughter shouldn’t get the HPV vaccine?
The vaccine is not recommended if a young women is pregnant, has certain blood conditions, an immune disorder or certain other medical problems. If you are thinking about having your daughter vaccinated, it’s a good idea to have a conversation with your daughter and her health care provider to see if there is any reason why she shouldn’t get the vaccine.
Should my daughter get the HPV vaccine if she is already sexually active?
What if she doesn’t know if she was exposed to HPV?
Yes. Girls and young women should receive the vaccine even if they have already had sex. It is not necessary for your daughter to have an HPV test before getting the vaccine.
Is the HPV vaccine safe?
The vaccine is considered safe by FDA standards. It does not contain mercury or thimerosal.
If my daughter already has HPV, will the vaccine help?
It depends on what type of HPV your daughter has been exposed to. The vaccine won’t cure an HPV infection that she has already, such as genital warts, pre-cancers (changes that happen before a cancer starts to grow), or cervical cancer. However, many people who have HPV are not infected with all four types of HPV that the vaccine targets. Since there is no test available to tell for sure if a young woman has had just one or all four types of the HPV virus, it is recommended to get the vaccine so she can have protection from the types she may not yet have come in contact with.
If my daughter gets the HPV vaccine will she be protected for the rest of her life?
It is not known how long your daughter will be protected after she receives the HPV vaccine because it hasn’t been available for that long. So far research studies have followed girls for 5 years after they received all 3 shots of the HPV vaccine and they are still protected. The levels of antibodies are very high, so protection is likely to last for a long time.
Is there an HPV vaccine for young men?
The HPV vaccine has only been approved for young women between 9-26 years of age. Scientific research is being done to determine if males would benefit from the vaccine. It may be possible in the future males will also be encouraged to get vaccinated.
Does insurance cover the HPV vaccine?
The vaccine is covered by most insurance plans but it is best to check directly with your family’s insurance provider. Since the HPV vaccine is new, it is possible that some insurance companies may not cover the cost of the vaccine. It may be expensive if your insurance company doesn’t pay for it. Each dose is about $120 (3 doses are needed to complete the series and for it to be effective).
Will there be a vaccine someday that prevents other types of HPV?
It would be wonderful if someday there could be a vaccine that works to prevent more types of HPV. In order for this to happen, a lot more research is needed. Currently, another new vaccine is being developed which is designed to fight against HPV types 16 and 18 (the two types that are connected with cervical cancer).
Having a vaccine that protects against the four types of HPV that cause serious problems including warts (6 & 11) and cervical cancer (types 16 & 18) is significant as it can prevent serious health problems and may even save lives. It is important to keep in mind that the HPV vaccine will protect your daughter from a few kinds of the virus but it won’t protect her from all of them. Help your daughter understand that it is still very important to see her gynecologist or health care provider for regular check-ups and Pap tests. |
