Promotion of influenza vaccines is one of the most visible and aggressive public health policies today. Twenty years ago, in 1990, 32 million doses of influenza vaccine were available in the United States. Today around 135 million doses of influenza vaccine annually enter the US market, with vaccinations administered in drug stores, supermarkets—even some drive-throughs. This enormous growth has not been fueled by popular demand but instead by a public health campaign that delivers a straightforward, who-in-their-right-mind-could-possibly-disagree message: influenza is a serious disease, we are all at risk of complications from influenza, the flu shot is virtually risk free, and vaccination saves lives. Through this lens, the lack of influenza vaccine availability for all 315 million US citizens seems to border on the unethical. Yet across the country, mandatory influenza vaccination policies have cropped up, particularly in healthcare facilities,1 precisely because not everyone wants the vaccination, and compulsion appears the only way to achieve high vaccination rates.2 Closer examination of influenza vaccine policies shows that although proponents employ the rhetoric of science, the studies underlying the policy are often of low quality, and do not substantiate officials’ claims. The vaccine might be less beneficial and less safe than has been claimed, and the threat of influenza appears overstated.
