What’s Behind the Flu Vaccine Shortage
The start of another flu season has found Americans facing a shortage of influenza vaccine. Although nearly 60 million flu shots will be available, vaccination is recommended for 185 million people at risk for complications. In a typical year, less than one-third of the U.S. population receives flu shots. Fortunately, since influenza is a contagious disease, it is not necessary to vaccinate everyone in order to stop widespread epidemics, or even to limit vaccinations only to those who are at risk. However, when there is a shortage, many people will seek the vaccine who might not otherwise have bothered.
