If you are the parent of a preteen, you may have heard about HPV and may be deciding if your child needs the HPV vaccine.
HPV, or the human papillomavirus, is the most common sexually transmitted infection in the United States. It affects both males and females — mostly in their teens and early 20s.
HPV is spread through intimate skin to skin contact – including vaginal, anal or oral sex with someone who has the virus – even if they don’t have signs or symptoms.
HPV comes in many different types. While most do not cause health problems, some can result in genital warts and cancers.
If you are a parent, you can protect your child with vaccination. HPV vaccination is recommended at ages 11 and 12 but can be started at age 9.
“The HPV vaccine is an important vaccine for both girls and boys,” says Erik Hogen, MD, a pediatrician at Scripps Clinic in Rancho Bernardo. “It is an extremely effective way to protect our younger generation against many types of HPV-related cancers.”
At Scripps, the HPV vaccine is available at Scripps HealthExpress walk-in clinics found throughout San Diego County. Scripps patients may also schedule an appointment with their primary care physician to get the vaccine.
How common is HPV?
More than 42 million are currently infected with HPV virus that causes disease, according to the Centers for Disease Control and Prevention (CDC).
Each year, about 13 million Americans become infected with HPV, including many teens, according to CDC.
Vaccine most effective when given early
The HPV vaccine series is most effective when given before any exposure to the virus. This is why HPV vaccination is based on age, not sexual experience.
“There is no reason to wait to vaccinate until they reach puberty or start having sex,” Dr. Hogen says. “Preteens should receive the immunization, so they are protected before ever being exposed to the virus,” Dr. Hogen says. “The vaccine produces a more robust immune response during these younger years.”
There is no evidence that giving the vaccine encourages early sexual activity, he says. And even if someone has already had sex, they should still get HPV vaccine.
HPV and cancer
Most HPV infections go away on their own within two years. However, some strains persist and are the cause of various cancers in adulthood, including cervical cancer and cancers of the anus, vagina and penis. Up to 70 percent of cancers of the head and neck are HPV-related.
Each year, about 37,000 people are diagnosed with cancers linked to HPV with about 21,700 in women, including more than 11,000 cases of cervical cancer. About 15,600 happen in men, including 12,500 cases of throat cancer.
More than 90 percent of these cancers could be prevented through vaccination, according to the CDC.
How is the HPV vaccine administered?
HPV vaccines are recommended for children between the ages of 9 to 12.
Those who get their first dose before turning 15, only need two doses. Those who get their first dose on or after they turn 15, need three doses.
HPV vaccination is generally not recommended after 26 since most people in this age range have been exposed to HPV already. However, adults 27 to 46 who were not adequately vaccinated may benefit from vaccination.
How effective is the HPV vaccine?
HPV vaccines are safe and effective. HPV infections and cervical precancers have dropped significantly since 2006 when HPV vaccines were first used in the United States.
Infections with HPV types that cause most HPV cancers and genital warts have dropped 88% among teen girls and 81% among young adult women, according to the CDC.
“Its efficacy is highest when the majority of the population is vaccinated prior to HPV exposure – which is why it is so important to vaccinate both boys and girls at an early age,” says Jo Marie Janco, MD, a gynecologic oncologist at Scripps Clinic.
Cervical cancer is the only HPV-related cancer that can be detected early by a recommended screening test. Other types of cancer caused by HPV may not be found until they cause more serious health problems.
“I strongly encourage parents to take advantage of this intervention that can prevent cancer for their children,” Dr. Janco says.
Vaccine is safe and accessible
Many people who get the HPV vaccine have no side effects at all. Some report mild side effects, including pain, fever, dizziness, headache, nausea, muscle or joint pain. Severe allergic reactions are rare.
“Years of testing are required by law to ensure the safety of vaccines before they are made available in the U.S.,” says Dr. Hogen. “Currently the U.S. has the safest, most effective vaccine supply in history.”
The Vaccines for Children program provides vaccines, including the HPV vaccine, at no cost to children who are 18 and younger who are uninsured, Medicaid-eligible, or American Indian/Alaska Native.
