-- The vaccine used to guard against the human papillomavirus does not lead young people and teens to engage in more unsafe sex, according to a study released today.
In spite of its success, just 57 percent of female teens received at least one dose and 38 percent of male teens had received all three doses in 2013, according to the CDC.
“I’d like to emphasize that it’s a real concern. It’s not something to automatically dismiss but that’s why we need some scientific evidence to show we’re on the right path,” said Jena, an assistant professor of Health Care Policy and Medicine at the Harvard Medical School.
The researchers looked at the medical history between 2005 and 2010 of 21,000 girls between the ages of 12 to 18, who had been given the vaccine, and compared them with 180,000 women who did not have the vaccine. The study found that the vaccinated women did not have higher rates of sexually transmitted infections, suggested they did not have increased rates of unsafe sex.
"This is a reasonable concern to have had, but the evidence suggests that it’s not important," Jena said. "[Physicians] can be reassured by these findings and use them to talk to their patients."
Because HPV is a sexually transmitted virus, Bednarczyk said some doctors are uncomfortable talking about potential sexual activity with their patients and their parents.
“Some of them even said, ‘I think 11 is too young to have this discussion with patient,” Bednarczyk said.
But Bednarczyk points out the vaccine is supposed to be given well before an adolescent is exposed to the virus through possible sexual activity and that the way the virus is transmitted does not need to be discussed in detail.
"Do you go into a detailed discussion about why it can spread and how it can spread?" said Bednarczyk, who pointed out doctors don't often go into great detail about how bacterial meningitis is spread before they suggest their patients get vaccinated. "This is a vaccine that’s recommended for you and it’s going to keep you from getting sick."
Bednarczyk also pointed out another reason the shot is recommended at a young age is because younger patients tend to have a stronger immune response than older teens.
