Yellow fever now states that a single dose of vaccination is sufficient to confer lifelong immunity against yellow fever disease." The attenuated live vaccine stem 17D was developed in 1937 by Max Theiler. The World Health Organization (WHO) recommends routine vaccinations for people living in affected areas between the 9th and 12th month after birth. Up to one in four people experience fever, aches, and local soreness and redness at the site of injection. In rare cases (less than one in 200,000 to 300,000), the vaccination can cause yellow fever vaccine-associated viscerotropic disease, which is fatal in 60% of cases. It is
Theiler's encephalomyelitis virus study the progression of a polio-like disease in mice. Theiler's encephalomyelitis virus Theiler's Murine Encephalomyelitis Virus (TMEV) is a single-stranded RNA murine cardiovirus from the family "Picornaviridae". It has been used as a mouse model for studying virally induced paralysis, as well as encephalomyelitis comparable to Multiple sclerosis. Depending on the mouse and viral strain, viral pathogenesis can range from negligible, to chronic or acute encephalomyelitis. The virus was discovered by virologist Max Theiler in 1937 while working at the Rockefeller Institute. Theiler discovered the encephalomyelitis virus during research on poliovirus-like paralysis symptoms in mice. That year Theiler had completed
