Why is there no plague vaccine?
Because human plague is rare in most parts of the world, there is no need to vaccinate persons other than those at particularly high risk of exposure.
Routine vaccination is not necessary for persons living in areas with enzootic plague such as the western United States..
How many died in the plague?
25 million peopleThe plague killed an estimated 25 million people, almost a third of the continent’s population. The Black Death lingered on for centuries, particularly in cities. Outbreaks included the Great Plague of London (1665-66), in which 70,000 residents died.
What sickness was the plague?
The plague is a serious bacterial infection that can be deadly. Sometimes referred to as the “black plague,” the disease is caused by a bacterial strain called Yersinia pestis. This bacterium is found in animals throughout the world and is usually transmitted to humans through fleas.
What was the last pandemic?
The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.
WHO found vaccine for plague?
The first plague vaccine was developed by Jewish bacteriologist Waldemar Haffkine in 1897. He tested the vaccine on himself to prove that the vaccine was safe.
What caused bubonic plague?
The plague is caused by bacteria called Yersinia pestis. It’s usually spread by fleas. These bugs pick up the germs when they bite infected animals like rats, mice, or squirrels.
Is there a cure or vaccine for the bubonic plague?
Unlike Europe’s disastrous bubonic plague epidemic, the plague is now curable in most cases. It can successfully be treated with antibiotics, and according to the CDC , treatment has lowered mortality rates to approximately 11 percent. The antibiotics work best if given within 24 hours of the first symptoms.
When was the vaccine for the Black Plague?
In 1936, a human live plague vaccine developed from an attenuated strain EV NIIEG of Y. pestis has been extensively used in Russia.
What stopped the Black Plague?
How did it end? The most popular theory of how the plague ended is through the implementation of quarantines. The uninfected would typically remain in their homes and only leave when it was necessary, while those who could afford to do so would leave the more densely populated areas and live in greater isolation.

Why did the plague kill so many?
The bubonic plague mechanism was also dependent on two populations of rodents: one resistant to the disease, which act as hosts, keeping the disease endemic, and a second that lack resistance. When the second population dies, the fleas move on to other hosts, including people, thus creating a human epidemic.
