New research shows many eligible people are not getting the shots.
The HPV vaccine, delivered as two or three doses, can significantly cut the risk of infection. It “is really one of the most effective vaccines we have,” said Dr. Lauri Markowitz, the HPV team lead in the Centers for Disease Control and Prevention’s division of viral diseases. But uptake remains stubbornly low: A report released by the C.D.C. this month showed that in 2022, only 38.6 percent of children ages 9 to 17 had received at least one dose of the HPV vaccine. Other new research suggests that HPV vaccination rates stalled in the wake of the coronavirus pandemic.
How does the vaccine work?
The HPV vaccine fools the body into thinking it has come into contact with the virus, marshaling antibodies in defense. Those antibodies can help clear the virus and prevent infection if someone is later exposed, which can happen through oral, anal and vaginal sex.
Who should get it? And how?
Children can be vaccinated starting at age nine. The C.D.C. recommends the vaccine for all preteens from the age of 11 or 12 and anyone up to age 26. It’s most effective before people are exposed to the virus, and “the assumption is that most people have started having sexual intercourse by age 26,” said Dr. Ban Mishu Allos, an associate professor of medicine at Vanderbilt University Medical Center.
The vaccine may still provide some benefit for people over age 26, and is approved up until age 45. The C.D.C. says that people between the ages of 27 and 45 might get the vaccine after talking to their doctors about their risk for new HPV infections.
Why are vaccination rates still low?
Researchers believe much of the hesitation stems from a key misunderstanding: “More people perceive it as a sexually transmitted infection prevention vaccine, as opposed to a cancer prevention vaccine,” said Kalyani Sonawane, an associate professor of public health sciences at the M.U.S.C. Hollings Cancer Center and an author of the new paper on parental attitudes toward HPV vaccination.
Dr. Sonawane’s research has also found that many parents are concerned about side effects. But doctors say many people do not experience side effects, and for those that do, the issues are generally mild and can include arm soreness, nausea, dizziness or, in some cases, fainting.
Doctors urge parents to vaccinate their children before they’re likely to become sexually active, which gives some parents pause, said Dr. Monica Woll Rosen, an obstetrician-gynecologist at the University of Michigan Medical School.
