Many (young) soldiers have had heart attacks after anthrax vaccinations. Could the two be related? The Army Medical Surveillance Activity (AMSA) compiled data on over 300,000 recipients of anthrax vaccine, and looked at their rates of heart attacks before and after anthrax vaccinations. This data was shared with the Institute of Medicine in 2001 at its request, and therefore became available to the public. Since then, this data (the Defense Medical Surveillance System) has been hidden from the public.
The rate of heart attacks (a.k.a. acute myocardial infarctions) was twice as high after anthrax vaccination [9.2 vs. 4.6 events per 100,000 persons/year]. Two related disorders, coded as "other acute and subacute form of ischemic heart disease" and "other forms of chronic ischemic heart disease" were more than twice as common after anthrax vaccination as before [18.8 vs. 7.1 total].
