    No, measles cannot mutate in such a way that the vaccine would no longer stop it. Measles doesn’t mutate anywhere near as quickly or dramatically as a disease like influenza, and it would need to simultaneously evolve the ability to bypass 5 (iirc) different human antibody types.

    Could it happen on an unlimited timeframe if humanity somehow loses the ability/technology to modify or retarget existing vaccines? Sure, in a few tens of thousands of years, but I don’t think Starfleet will still be using our current MMR vaccine in the year 22,026.

    Hope this helps or assuages fears. The real problem is insufficient vaccination causing gaps in herd immunity. I recommend vaccinating schoolchildren without their parents’ consent.
