What is leprosy vaccine?

Leprosy vaccine is a Category I vaccine and is required to be administered to children according to the national immunization program.

Leprosy is measles and rubella. Measles is an acute respiratory infectious disease caused by the measles virus, with clinical manifestations including fever, rash, cough, runny nose, etc. In severe cases, it may be complicated by pneumonia, myocarditis, and encephalitis. Rubella is an acute respiratory infectious disease caused by the rubella virus, with clinical manifestations including fever, rash, and enlarged and painful lymph nodes behind the ears, under the occipital bone, and in the neck. The greatest harm caused by rubella is that congenital rubella syndrome may occur after a pregnant woman suffers from rubella. Congenital rubella syndrome can cause miscarriage and stillbirth. When the mother transmits the rubella virus to the fetus, congenital damage such as congenital cataracts, congenital heart disease, deafness, and intellectual disabilities may occur. After vaccination, this vaccine can stimulate the body to produce immunity against measles virus and rubella virus.
