I had to deal with a ‘SIDS’ death in the Army. It occurred on the night of the 6-month (MMR) vaccination. I asked the attending hospital nurse if she though the vaccine had anything to do with the child’s death. Her response: “we’re not supposed to talk about that”. Dead and damaged babies are the cost of the Faustian Deal the medical community has made since the late 1800s to stop commonplace outbreaks of cholera, rubella, etc. which were spread in open air markets and in poor sanitation. With under developed immune systems the babies were the vectors so they were the targets for immunization. I don’t see people throwing garbage and sewage in public, open-air food markets yet I do see children dying and damaged from vaccines used to combat the ghosts of 19th century sanitation.
If someone let it run untreated I could see complications . . . but SIDS is another issue altogether. There's still no satisfactory explanation.
The nurse may have been told not to connect the two because there was no connection, not because there was a conspiracy.
But anti-vaccine agitators have their minds made up, they are convinced that pediatricians and drug companies are conspiring to kill their clients.
