After receiving the measles vaccine this past Wed, 4 children from Tamil Nadu, India have died of brain hemorrhage due to anaphylactic shock. Two possible explanations for the deaths have been offered: 1) the people giving the vaccine mixed the vaccine with something other than saline; 2) vaccine contaminated by some pathogen after reconstitution. It is also possible that the vaccine company is not using safe vaccine production techniques and a team is being dispatched to investigate this. Oddly, these deaths all occurred from vaccine constituted from the same vial, but another 230 kids also inoculated with this vaccine did not suffer any consequences (except for boosted immunity!).
