To the Editor: There have now been 3 randomized controlled trials investigating the effectiveness of influenza vaccine in preventing sick leave by healthy working adults.1- 3 Two trials1,2 explicitly calculated the cost-effectiveness of vaccine provision but appear to give conflicting results. The relative newness of randomized cost-effectiveness trials is reflected in several unresolved methodological issues, which we believe to be the source of the disagreement.
