“He said he found it odd because they really thought the flu shot would be much more effective vs last year.”
I remember reading a few months ago that the flu vaccine was predicted to be 48% effective this season which was higher many previous seasons. If flu was bad this season then maybe some of it was the Wuhan coronavirus. Funny both my wife and sister in law came down with a dry cough and fever in Feb. I didn’t catch it but was sick in Jan. We all had flu shots.
A lot of people got the same, with flu shots.
