New research suggests the HPV vaccine is preventing cancer in men, as well as in women, but fewer boys than girls are getting the shots in the United States.
The HPV vaccine was developed to prevent cervical cancer in women and experts give it credit, along with screening, for lowering cervical cancer rates. Evidence that the shots are preventing HPV-related cancers in men has been slower to emerge, but the new research suggests vaccinated men have fewer cancers of the mouth and throat compared to those who didn’t get the shots. These cancers are more than twice as common in men than in women.
For the study, researchers compared 3.4 million people of similar ages — half vaccinated versus half unvaccinated — in a large health care dataset.
