HPV Vaccine FAQs
If you have a school-aged son or daughter, you’ve probably heard about the HPV vaccine from your pediatrician. Understanding the facts behind this vaccination is important as it prevents very serious health problems later in your child’s life, including certain cancers. It is recommended that all children get the vaccine starting at age 9.
Every year in the United States, 13 million new people become infected with HPV. 90% of people who develop HPV-related cancers could have prevented their cancer diagnosis by receiving the HPV vaccine.
Your pediatrician is here to help you understand why early vaccination against HPV can help to better protect your child. Schedule your child’s vaccine appointment today or review our frequently asked questions below.
About HPV
- HPV is a group of viruses that cause warts.
- Warts caused by HPV can sometimes become precancerous or even cancer-causing lesions.
- HPV has been linked to cancer of the mouth and throat.
- Most HPV infections are transient and are cleared by the body.
- Some types of HPV (the ones covered by the HPV vaccine) are harder for the body to clear and may lead to precancerous and cancerous lesions.
- An estimated 20 million people in the US currently have an HPV infection.
- People who become sexually active have greater than a 50% risk of getting HPV.
- An estimated 80% of sexually active women will have contracted HPV by the time they are 50.
- Even in women with only one lifetime partner – some studies suggest that there is still a 20% risk of HPV infection. This is likely attributed to the sexual history of her partner.8
- The infection lasts for up to 24 months.
- Most people do not know they are infected, which is why the virus is easily transmitted.
- HPV cancer typically does not have symptoms until the virus is advanced, serious and more difficult to treat.
- The types of HPV that can cause genital warts are not the same as the types of HPV that cause cancers.
- People are often infected and not aware, which further transmits the virus.
- Women can be screened for cervical cancer via a pap smear. However, there aren’t screenings for other cancers caused by HPV. That is why it’s so important to prevent infection with the HPV vaccination.
- When a person is exposed to HPV, and the virus survives, the virus can lead to the change of normal cells into cancerous cells.
- While the immune system typically recognizes infected cells and eliminates them, in some instances the infection persists and causes the cells to mutate.
- The mutations can ultimately lead to cancer.
- Cancers that are linked to HPV are cancer of the cervix, the back of the throat, anal and penile.
- Yes, UPMC CCP providers have vaccinated their children.
- UPMC CCP providers themselves have been vaccinated.
- Like other vaccine series, it’s important to get the HPV vaccine earlier rather than later. Research shows the body will generate a much stronger immune response if HPV vaccination occurs before, rather than after, exposure to the HPV virus.
- If you wait to vaccinate your child, he or she may need to receive three shots, instead of the two.
About the HPV Vaccine
- 2022: The CDC and CCP have changed their recommendation to administer the HPV vaccine at age 9. Data continues to show that providing the vaccine at a younger age promotes a stronger immune response.
- 2016: The CDC made a formal recommendation for a two-dose, or two-shot, series of HPV vaccine for children starting the series prior to their 15th birthday. Those starting after their 15th birthday still require 3 shots. This recommendation comes from data showing a stronger immune response for vaccine series initiated prior to age 15, preferably at age 11-12.
- 2014: A 9-valent human papillomavirus (HPV) vaccine (Gardasil 9, Merck & Co., Inc) was licensed for use in females and males in the United States. (CDC Website)
- 2011: ACIP expands HPV vaccine recommendations to include routine immunization in males.
- 2010: FDA license extended for the prevention of anal cancer in males and females.
- 2009: Licensed by the FDA for use in males to prevent genital warts.
- 2006: FDA licenses HPV vaccine for use in females ages 9 to 26 years old to prevent cervical cancer, vaginal and vulvar cancers, and anogenital warts. The Centers for Disease Control’s Advisory Committee on Immunization Practices (ACIP) votes unanimously to recommend that all girls ages 11 and 12 receive the vaccine.
- The Gardasil HPV vaccine is directed against 9 strains of HPV (types 6, 11, 16,18, 31, 33, 45, 52, and 58).
- HPV 6 and 11 are associated with 90% of anogenital warts.
- HPV 16 and 18 are account for 75 percent of all cases of cervical cancer.
- HPV 18, 31, 33, 45, 52, and 58 account for about 15% of cervical cancers.
- Boys are at risk for cancers caused by HPV also.
- HPV-associated cancers in males include anal, penile, and oropharyngeal (mouth and throat) cancers.
- An estimated 22,000 annual cases of HPV16- and HPV18-associated cancers occur in the US each year. Of these, 7,000 occur in males.3
- Patients who have ever had a life-threatening allergic reaction to HPV vaccine or any of its components, including to yeast.
- Although safe to administer to patients on chemotherapy or other immune-suppressing medicines, it may not create a full immune response in patients with a weakened immune system.
- The HPV vaccine has been proven safe and effective and has been evaluated in numerous randomized control trials worldwide.
- Organizations such the Centers for Disease Control and the National Vaccine Injury Compensation Program actively monitor the safety of the vaccine and investigate reports of adverse events.
- Most reported adverse events are transient and mild, including injection site reactions, fever, and syncope (fainting). All of these reactions, especially fainting have also been noted with the administration of other adolescent immunizations.5
- No causative link has been established between serious neurologic events (such as Guillain-Barré Syndrome and seizures) and HPV immunization.1,5,6
- Multiple studies have shown that starting the HPV immunization series does not result in increased sexual activity.9,11
- There are many social, ethical, and cultural factors that contribute to the sexual behavior of adolescents. Vaccination has not been shown to contribute to this behavior.
- It is important to be vaccinated against HPV prior to sexual exposure. Remember, an estimated 80% of females will have been exposed to HPV by age 50. Therefore, it is important to take into account your child’s lifelong health beyond their pediatric years.
- Vaccinating against HPV does not mean that you or your health care provider encourages sexually promiscuous behavior. It does create an opportunity to speak with your preteen/teen about risk taking and the importance of good decision-making.
- Yes. Aluminum is in vaccines that prevent hepatitis A, hepatitis B, DTP, Haemophilus influenzae type b, HPV and pneumococcus.
- Aluminum is present in certain vaccines to improve the immune response. For more than 70 years, aluminum salts such as aluminum hydroxide, aluminum phosphate and aluminum potassium sulfate have been used to improve the immune response to vaccines.
- Healthy babies and children quickly eliminate aluminum from their bodies without harmful effects.
- By the time we are adults, we will have accumulated between 50 and 100 milligrams of aluminum. It’s important to note that almost all that aluminum comes from food.
