Some vaccines protect against more than 1 disease
Some vaccines provide protection against more than 1 disease in a single vaccine. For example, the measles, mumps, and rubella (MMR) vaccine is just 1 injection. This means fewer vaccination appointments and fewer injections.
It is not always possible to have a different vaccine if you want protection against only one of the diseases. Your immune system is used to dealing with thousands of viruses and bacteria every day — there are no safety concerns with having multiple vaccines at the same time.
