The measles vaccine is not the same as the leprosy vaccine, as the two vaccines prevent different diseases and the timing of the vaccination is different. The measles vaccine is a combination of measles and rubella vaccine, which can effectively prevent both measles and rubella, while the measles vaccine can only prevent one disease, measles, which is injected when the baby is about 8 months old, and the measles vaccine can only be injected after the baby is 1 year old. In addition to the above two vaccines, there is also a MMR vaccine, which is a combination of measles, mumps, and rubella, and is also a common vaccine that infants receive at 18 months of age. Therefore, the MMR and measles vaccines are not the same vaccine, but the MMR vaccine is one more vaccine than the measles vaccine to prevent rubella. Both vaccines are Class A vaccines as stipulated by the state, and it is recommended that mothers inject their babies on time according to the vaccination book.
