There is no effective treatment for smallpox disease after the outbreak.
Only the treatments to manage symptoms are available. However, vaccination
can be effective up to 4 days after exposure and before the appearance of
rash.

Vaccine
The smallpox vaccine is made from a virus called vaccinia, a virus closely
related to smallpox. Unlike many other vaccines, which contain dead virus,
the vaccine contains the “live” vaccinia virus. However, the
vaccine can not give one smallpox, because the virus it contains is not
the smallpox virus.
The smallpox vaccine provides immunity that lasts up to 3 to 5 years and
dwindles thereafter.
It shows 95% success rate in protecting people against the smallpox virus
and can also prevent or significantly lessen the severity of infection when
given within 3 days after exposure.
