There’s more bad news about the flu: The main strain of flu that’s circulating right now doesn’t exactly match what’s in this year’s flu shot, according to a new report.
However, the strain in the vaccine may still be close enough to offer some protection, officials said.
The news comes amid a particularly severe flu season in the U.S.; the season started early, and it’s unclear if flu activity has peaked yet.
