TORONTO - Another storm may be brewing for the coming flu season: A component of the seasonal flu shot may not be well matched to the circulating viruses, potentially setting up what's known as a vaccine mismatch.
Some samples of the emerging new strain of H3N2 viruses show a substantially reduced response to antibodies generated by the corresponding virus in the seasonal vaccine, raising the possibility of significantly reduced protection in some cases.
