Should you get the mmr shot if you have already had measles or the mumps?

Yes, it is generally recommended to get the MMR (measles, mumps, and rubella) vaccine even if you've had measles or mumps. Natural infection may provide some immunity, but vaccination ensures a more robust and lasting immune response. Additionally, the vaccine helps protect against rubella, which you may not have had. Always consult a healthcare provider for personalized advice.
