    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.

      It’s a fair question. Plenty of viruses do mutate rapidly, especially other RNA viruses.

      Measles can’t do it because of the lucky fact that the change required to escape immunity requires multiple simultaneous mutations that would render it likely unable to attach to human cells.

      Is that high school knowledge?

        Well, in MY school it was (RNA vs DNA viruses and their “virulence”. And how vaccines work). Just like Geography and World History. 🤷‍♂️

          Yeah and measles is an RNA virus.

          RNA viruses are the ones that typically mutate more rapidly, more easily escape immunity, which is why measles not being able to escape immunity is a pretty fair question imo, with an interesting answer that isn’t exactly intuitive.
