Flu shot mismatched on B virus, early data suggests: "It appears there may be a partial flu shot mismatch again this year, with early data from Canada, the United States and Britain suggesting the vaccine component meant to protect against influenza B is not a match for the flu B viruses causing the most disease.
Predicting which family of influenza B viruses will dominate in a coming year — and therefore should be covered by the flu shot — is a challenge that has defied the experts in five of the last seven flu seasons, at least so far as disease patterns in North America are concerned."

On top of everything else, this. And Al Franken is a Senator.
