Tom Jefferson of the Cochrane Institute says that Most studies are of poor methodological quality and the impact of confounders is high. I agree. Please would you refer me to some of the best studies on the efficasy (sic) of seasonal flu vaccines. After a critical appraisal of the best studies you know of I’d like to submit the same for publication in the interest of science.”
