HPV vaccines that work in US women may miss the target in women from other countries

Most cervical cancers are caused by persistent infection with high-risk human papillomavirus (hrHPV). Different vaccines are available to protect against HPV. Researchers at Dartmouth’s and Dartmouth-Hitchcock’s Norris Cotton Cancer Center have shown a very different prevalence of hrHPV in Honduras compared to the United States, and concluded that the same vaccination programs that target hrHPV strains in the U.S. may not be as effective in protecting women in other countries from the disease.
