Better begin vaccinations yesterday.
Vaccines after an epidemic don't do much.
Small pox is only a threat as a bio-weapon because it no longer exists as a common communicable disease.
If not for this threat there is no need to produce large amounts of the vaccine. And there is no reason to stockpile it. The idea of a vaccine is to immunize people before they are exposed to the virus.
Thanks for posting this.
The value of vaccines, especially smallpox vaccines is widely argued. It is reportadly not nearly as contagious as usually reported. Bad effects of the vaccine are in fact reported as worse than not vaccinating. In the case of smallpox, the vaccination is supposed to be effective for a short period of time after exposure.
