Why a Single Dose HPV Vax Could be a Game-Changer

  • HPV is the most common sexually transmitted infection in the U.S.
  • Getting the HPV vaccine can significantly decrease the risk of developing the disease.
  • Currently, the HPV vaccine is given as a three-dose regimen.
  • A new study finds that the vaccine may be effective after a single dose.

A single dose vaccine may be highly effective in preventing human papillomavirus (HPV), according to newly published research. HPV is the most common sexually transmitted infection in the United States, according to the Centers for Disease Control and PreventionTrusted Source (CDC), and certain strains of the virus can lead to cervical cancer. Currently, the standard for HPV prevention is a three-dose vaccine regimen.

But now, researchers find a single-dose vaccine may be enough.

A randomized controlled trial of 2,275 women in Kenya showed that a single dose of the HPV vaccine was highly effective. According to the investigators in the trial, the results could help the WHO reach its goal of having 90 percent of 15-year-old girls vaccinated against HPV by 2030, up from the current statistic of 15 percent of women worldwide vaccinated.

What is HPV?

HPV is the most common sexually transmitted infection in the United States. According to the CDC, approximately 43 million people had HPV in 2018, mostly those in their late teens and early 20s. There are many different strains of the HPV virus, and the majority of the strains clear up on their own within two years without causing any other health problems. However, some strains are more serious than others and can contribute to more serious conditions, including genital warts and cancers.

HPV is spread through vaginal, anal, or oral sex with someone who has the virus. The virus can be spread even when someone does not have any symptoms. Symptoms of the virus can also develop years after a person was exposed to the virus, which makes it incredibly difficult to determine when a person contracted the disease.

While the majority of HPV can clear up on its own, certain HPV can cause cervical and other cancers, like cancer of the vulva, vagina, penis, anus, and throat. Unfortunately, there is no way to know who will develop cancer from HPV.
