The flu shot is still your best defense against the virus.


This year’s flu season proved to be one of the worst in decades, and new evidence shows it isn’t over yet.
The Centers for Disease Control and Prevention issued a warning this week that a new strain of flu is making a push in the U.S.
Oklahoma Medical Research Foundation immunologist Eliza Chakravarty, M.D., said the predominant strain for this season’s outbreak has been influenza A, specifically H3N2. Cases of this strain of flu are now on the decline. But flu cases involving another strain—influenza B—appear to be surging.
“Flu season is generally winding down, but we aren’t in the clear, and people need to remain vigilant in protecting themselves and their families, especially young children,” said Chakravarty. “Influenza B can be just as serious as influenza A, and it has been known to be severe in young children.”
Even though this year’s flu shot proved largely ineffective against H3N2, it does appear to be far more effective in preventing influenza B. This means getting a flu shot is still your best possible defense against contracting the virus.
“It is actually possible to get sick with multiple strains of the flu during a single season,” said Chakravarty. “The flu is miserable. Don’t go through it if you don’t have to, especially twice.”
From Sept. 1 through March 17, the Oklahoma State Department of Health reports 242 flu-related deaths in the state, as well as more than 4,450 hospitalizations.
“If you can physically get the flu shot, do it, even this late into the flu season,” she said. “This virus is deadly. You will not get the flu from the shot; that is a myth that needs to be eliminated. The shot can save your life or the life of someone you love.”
