Vaccinate against measles
1. Serological effect of vaccine: Antibodies began to be produced at 1 week after vaccine injection, and peaked at 1 month, with a positive conversion rate of over 95%.
2. The epidemiological effect of the immunized population is consistent with the serological effect after immunization, that is, those with positive antibodies can avoid the disease.
3. Effect of emergency vaccination: When infected with wild measles virus, the virus first passes through the respiratory mucosal barrier and then enters the serum through the lymphatic system. The incubation period is about 7- 14 days. The route of vaccination is different from natural infection. Generally, antibody production begins on the 7th day after vaccination, which is much shorter than that after infection. This is the basis of emergency vaccination to control the epidemic. When a measles epidemic occurs in a certain place, it can reduce the incidence and prevent the epidemic by carrying out emergency vaccination on the surrounding contacts as soon as possible.
Antibodies can be produced after 2 weeks of measles vaccine injection.
