2004 FEB 11 - (NewsRx.com & NewsRx.net) -- Two surveys conducted by Harris Interactive suggest that the flu vaccine used to vaccinate people before and during last winter (2002-2003) was not perceived as effective in preventing flu.
The first survey was designed to measure how many people had tried and failed to be vaccinated, as well as to measure public perceptions of the effectiveness of flu shots and of attitudes about the distribution and availability of vaccine for this current flu season.
The results of this survey were published in The Wall Street Journal Online Health Industry Edition on December 30, 2003.
However, one finding in that survey appeared to warrant further study. The finding was that there was no perceived correlation between having a flu vaccine shot and not getting the flu.
In light of the seriousness of this finding, Harris Interactive decided to repeat the survey and to add two additional questions. These questions were whether people who claimed to have had the flu had spent one day or more in bed, and whether a doctor had diagnosed the flu.
We wanted to test a possible explanation for the remarkable finding - that many people who did not get the flu, but had colds or coughs for example, thought they had flu.
The results of the second survey confirmed the results of the first survey and strengthened the evidence that the flu vaccine used in 2002-2003 was perceived as not effective in preventing flu.
