Question
Is the MMR vaccine effective in preventing pediatric paralysis?
Answer
The MMR vaccine is a live attenuated vaccine used to prevent measles. It is made from a measles virus attenuated strain. There are some contraindications for receiving the vaccine, such as a history of egg or neomycin allergy, known immune deficiencies, or long-term immunosuppressive drugs, as well as severe or extreme malnutrition. During the period of receiving the MMR vaccine, if there is a fever (body temperature above 38 degrees Celsius), injection of immunoglobulin last month, or administration of a live attenuated vaccine last month, vaccination should be temporarily suspended. Generally, there will be no local reactions after injection, but a few people may experience fever within 6 to 10 days, usually not exceeding 2 days, and occasionally scattered rashes.
