Drug Company Money is Top Factor in Publication of Vaccine Studies
Flu vaccine studies that are funded by industry are significantly more likely to be published in prestigious journals and to later be cited in the scientific literature than studies without such funding, according to a survey of 274 studies conducted by researchers from the Cochrane Vaccine Field in Italy, and published in the British Medical Journal.
Overall, the authors also found that most flu vaccine studies were of poor quality, with only 18 percent of them reporting conclusions that were actually supported by their findings (concordance).
The researchers also found that studies supporting the effectiveness of flu vaccines tended to be more poorly designed than studies not supporting their effectiveness. Concordance was also significantly lower in studies supporting vaccine effectiveness than in those refuting it -- meaning that most studies failed to support the effectiveness of the flu vaccine.
