9-Valent HPV Vaccine Effective

Adding more strains of human papillomavirus could increase protection. A vaccine targeting nine cancer-causing strains of human papillomavirus (HPV) -- rather than two or four -- was highly effective in preventing disease, researchers reported. In a randomized, controlled trial, the nine-valent vaccine was 96.7% effective in preventing high-grade cervical, vulvar, or vaginal disease associated with its five new HPV strains, Joura and colleagues reported in the New England Journal of Medicine. http://www.medpagetoday.com/InfectiousDisease/Vaccines/50082?xid=nl_mpt_DHE_2015-02-19&utm_content=&utm_medium=email&utm_campaign=DailyHeadlines&utm_source=ST&eun=g721819d0r&userid=721819&email=amydugan2%40gmail.com&mu_id=5883165&utm_term=Daily
