Here's an excerpt from the Diphtheria and Tetanus shot package insert, Page 11, 3rd paragraph >
http://www.fda.gov/downloads/BiologicsB ... 101580.pdf
Adverse events reported during post-approval use of Tripedia vaccine include idiopathic thrombocytopenic purpura, SIDS, anaphylactic reaction, cellulitis, autism, convulsion/grand mal convulsion, encephalopathy, hypotonia, neuropathy, somnolence and apnea. Events were included in this list because of the seriousness or frequency of reporting. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequencies or to establish a causal relationship to components of Tripedia vaccine.
Now I know why they decided to call an injection a SHOT!
