Vaccine For The Plague

For those of you who are susceptible to diseases from the Middle Ages, things are looking up. They may have developed a vaccine that works against the Black Plague.

The vaccine, which is taken orally or by injection, was given to rats at UCF and the efficacy was evaluated by measuring immunity (antibody) developed in their blood.

All untreated rats died within three days while all orally immunized animals survived this challenge with no traces of the plague in their bodies. The rats were exposed to a heavy dose of Yersinia Pestis bacteria, which causes the plague, at the U.S. Army Medical Research Institute of Infectious Diseases in Maryland. It is one of a few labs in the world authorized to store and work with the highly dangerous agent.

The vaccine can be taken orally, so no need to mess with nasty needles. I'm sure the rats are happy about that bit.
