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).
