After returning to England, she tried convincing physicians
of the inoculation idea, but they, of course, were disdainful. Nevertheless,
she talked one physician into inoculating her daughter, who was three at the
time. The procedure went well. After a time, Lady Mary succeeded in convincing
a few more physicians to give it a try (actually, experimenting on prisoners).
The rest, of course, is history, except that a physician named Edward Jenner, noting
that milkmaids never got smallpox, figured out that inoculating people with
cowpox was safer and more effective than inoculating with smallpox. Of course,
Jenner gets the credit for the vaccination idea. Incidentally, the term, vaccination, comes from the latin word vacca, for cow. (In case you've forgotten, being inoculated with small doses of virus primes your immune system such that it can quickly attack an invader it "remembers.")
Today there is no smallpox. Not a single case on earth since
the 1970s. Thanks to vaccinations, it’s been wiped out. Except, that is, for
one mishap. In 1978, Janet Parker, a photographer in Birmingham, England, got smallpox
after taking photographs of tissues and organs for doctors’ files. Somehow,
she’d come into contact with samples that were supposed to have been locked
away. Other people caught it from her. Parker died. Within a few years of her
death all lab stocks of smallpox virus in the world were destroyed except for
some samples kept in two tightly locked-down laboratories, one in the US and
one in Russia.
Since the Parker incident in 1978, no one has had smallpox. In the US, routine smallpox vaccinations for every child were discontinued in 1971 and only a small fraction of humans are immune to it (old people who had it and survived). Today the only samples of the smallpox virus are kept in two tightly locked-down labs, one at the CDC in Atlanta, and one in Russia.
After 9/11 the US started a crash program to stockpile
millions of doses of the smallpox vaccine. Gotta watch out for those Russians.
