Plague vaccine is a vaccine used against Yersinia pestis to prevent the plague. [1] Inactivated bacterial vaccines have been used since 1890 but are less effective against the pneumonic plague , so live, attenuated vaccines and recombinant protein vaccines have been developed to prevent the disease.
Smallpox was a dangerous disease caused by the variola major virus. The most common type of smallpox, ordinary, historically has devastated populations with a 30% death rate. The smallpox virus is transmittable through bodily fluids and materials contaminated with infected materials.
Smallpox was an infectious disease caused by variola virus (often called smallpox virus), which belongs to the genus Orthopoxvirus. [7] [11] The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, [10] making smallpox the only human disease to have been eradicated to date.
Morici said there is need for more research, because while the vaccines used in other parts of the world work against bubonic plague, there isn't strong evidence to show they protect against the ...
Smallpox vaccine was available in Europe, the United States, and the Spanish Colonies during the last part of the century. [4] [5] The Latin names of this disease are Variola Vera. The words come from various (spotted) or varus (pimple). In England, this disease was first known as the "pox" or the "red plague".
How do you treat the plague? The plague was never eradicated, but we've gotten better at preventing its spread and treating it in humans. When treated early with antibiotics, the plague can be cured. The key is to get to a doctor fast -- otherwise the plague can be deadly. And, as the old adage goes, prevention is better than a cure.
The smallpox vaccine is used to prevent smallpox infection caused by the variola virus. [10] It is the first vaccine to have been developed against a contagious disease. In 1796, British physician Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus.
The virus targets the nervous system, which is why it sometimes triggers spinal and respiratory paralysis—and death. Polio primarily infects children under 5 and has done so around the globe for ...
