hello and back after some thought
Pret -- I appreciate all that you are doing with this info! and didn't want to argue about the vaguer vaccine testing issue.
But I just wanted to make the point that though your confidence may remain undented that adverse events are inevitably spotted in clinical testing and investigated -- and following that, in general population use, I think it is misplaced.
With your experience, I'm sure you know that many adverse events in drug tests are dismissed as "background". For example, say 1,000 six month old babies are testing a vaccine. Say that during the period of the test, 10 babies would be expected to be admitted to hospital ANYWAY with encephalitis (I am completely making these figures up for the sake of the example.)
So if up to ten babies in the test can be admitted to hospital suffering encephalitis during the period of the trial without it being investigated because they are "background" events.
If you think this does not happen you are wrong. It happens even with deaths.
