-Influenza vaccines given in prior years may provide protection against the flu for more than one year, according to a study published online today in the journal Clinical Infectious Diseases.The study, conducted by flu experts at Marshfield Clinic Research Foundation and the Centers for Disease Control and Prevention, also reported protection from the flu, due to vaccination, was greatest among people who had no history of flu vaccination in the prior five years.
Researchers found adults had similar levels of protection if they received the flu vaccine in the current season, the previous season or both seasons. They also found that vaccine effectiveness was 27-41 percent higher for adults who were vaccinated for the first time in the past five years compared to those who got the vaccine almost every year.
