How can mumps be prevented?
There is a vaccine against mumps. The vaccine is usually given together with measles and rubella in a vaccine shot called MMR. The vaccine usually produces life-long immunity.

However, vaccination schedules differ considerably in different countries.

Is the MMR vaccine safe?
The MMR vaccine is safe and effective and generally has very few side effects. Mild reactions such as fever, redness or swelling at the injection site have been reported. Following media publicity surrounding a report published in 1998 claiming a link between MMR vaccination and autism, public confidence in some countries has been undermined. Findings of subsequent studies have shown no link between vaccination and autism. Indeed no health regulatory body in the world has changed its policy on measles vaccination as a result of this hypothesized link.
