CDC Report Says This Season’s Flu Vaccine Has Been 48% Effective So Far

The flu vaccine has been 48% effective so far this season, according to a report from the Centers for Disease Control and Prevention. Brendan Flannery, an epidemiologist at the CDC’s influenza division, said, “The 48 percent overall is not as good as we would like to see for flu vaccine, but the protection we see is significant.”

CDC officials said that “elevated” influenza activity is expected to continue for several more weeks in some parts of the US.
