Typhus Vaccine Adverse Reactions
Typhus vaccines were developed in 1940 by Hans Zinsser and have been a disaster ever since due to adverse effects, death and causing typhus itself. In one study, a group of 290 persons inoculated with the vaccine, and 218 (to percent) developed symptoms and serological manifestations of typhus fever. There was one fatality.
Discontinued for Cause
Production of typhus vaccine in the United States has been discontinued and there are no plans for commercial production of a new vaccine. Vaccination against typhus is not required by any country as a condition for entry.
Dangers Associated with the Use of Living “Attenuated” Typhus vaccine
Typhus is Easily Resolved
Typhus is rare, and treatment of all forms of typhus is similar. Chloramphenicol, doxycycline or other forms of tetracycline result in rapid resolution of fever and relapses are infrequent. Vaccination is inappropriate.
Tourists at Minimal Risk of Typhus
Typhus is extremely rare and is only a concern in highland populations in Africa and South America. Tourists are at minimal risk of acquiring lice and disease. Vaccination is unnecessary and production of typhus vaccine in the United States has been discontinued. There are no plans for commercial production of a new vaccine.
Typhus is any one of several similar acute diseases passed from human to human by the body louse and caused by Rickettsia bacteria. The name comes from the Greek typhos, meaning smoky or hazy, describing the state of mind of those affected with typhus.
