CDC Releases Interim Flu Vaccine Effectiveness Report
February 26, 2020 10:01 am Chris Crawford – According to a Feb. 21 CDC Morbidity and Mortality Weekly Report, the current influenza vaccine has been 45% effective overall against 2019-2020 seasonal influenza A and B viruses.
Specifically, the flu vaccine has been 50% effective against influenza B/Victoria viruses and37% effective against influenzaA(H1N1)pdm09.
According to former AAFP Vaccine Science Fellow John Epling, M.D., M.S.Ed., of Roanoke, Va., that means the vaccine is about as effective as it typically is in a season when it offers a decent match to circulating influenza antigens.
