WHY? is what I would like to know, it did no harm to have the inoculations, so why stop them.
Want to guess where those inoculations came from, what source, SMALLPOX virus itself. Now they say that is not safe, guess not, cause it don't cost enough.
They stopped giving the vaccinations because smallpox no longer exists “in the wild”.
A contract for a smallpox drug? Half a billion dollars worth? Who on earth could it have possibly been tested on? Nobody has had smallpox for years. That passed FDA testing requirements for safety and efficacy? Impossible.
How large acceptable risk is depends on the death rate of the virus, (Does it kill nine in ten or one in ten million) and how likely it is that you will come in contact with it.
In the case of the smallpox vaccine you had one change in one hundred thousand of having a life threatening reaction and a two in a million chance of dying. That is really good odds except if there is no chance of you catching the virus in the wild. In which case it is easy to argue that you killed them for no reason.
That is the reason they stopped giving the vaccine.
