I guess we're not really communicating very well.

Let's change tack slightly. Say that we had a vaccine for a deadly disease and 1 million people were vaccinated with it. And let's say that out of that 1 million people, 1000 died as a side effect of the vaccine, while 2001 people avoided certain death (and let's say that we are in a position to know that with absolute certainty).

Do you think such a vaccine would be considered successful?

I guess I should clarify that when I say "considered successful" I mean: a) by the general population and b) by the medical profession.
