No. Viruses do not “metastasis”. That is what cancer cells do.

Perhaps the word you were looking for was “mutate”.
Viruses mutate but some more than others. Measles is one of those viruses that mutates very slowly overtime and without much genetic drift. If that were not the case, a person who once came down with measles could come down with it again and again such as we do with rapidly mutating viruses like the common cold (a rhinovirus) or influenza and one would have to as with influenza, get a new measles vaccine once a year.
Whatever 40 hour “health” course you took, I hope it was free otherwise you really need to ask for your money back.
Yes it was a typo. I meant mutate. Anyhow, you know what I meant.
Let’s see I have not been sick in 7 years now, and you are saying that I got ripped off? Oh okay.....LOL!
I’m glad you admit it mutates. Although you say it’s slow to imply the vaccine is the same mutation.
Do you know how long it takes to come up with a vaccine, test it, get it approved and then mass produce for distribution? LOL!
