CDC: Flu Vaccine Was Only 19% Effective This Season.

reports that flu vaccines “were only 19% effective in preventing doctor visits for influenza this season, one of the lowest rates in the past decade, the Centers for Disease Control and Prevention said Thursday.” Brendan Flannery, an epidemiologist in the CDC’s Influenza Division, said the viruses used to make the vaccine this year weren’t a good match for the dominant strains of influenza in circulation. In the past decade, “effectiveness rates for flu shots have ranged from 10% to 60%, according to the CDC.” http://www.usatoday.com/story/news/2015/06/04/flu-shot-effective/28465601/
