NEW YORK Only 12% of adults think they had the flu this past winter, fewer than the 15% to 21% who thought they had the flu in other winters since 2004, Harris Interactive reported Friday.
There is no evidence, however, that flu shots should get the credit for the decline in the number of people with the flu, though conversely, Harris Interactive also cautioned in its release there is no evidence that flu shots didn’t contribute on some level.
