You're right about two things: one, the chalkboard gag was recycled, and two, there's no reason to not have gotten the MMR vaccine in 1991. It's worth commenting that the writer of this episode would have been a child before the MMR vaccine was commonplace, however.
That definitely makes sense--I was born in 1993 and absolutely got the MMR vaccine, but I was unsure of when it was invented and frankly too lazy to look it up. Still odd that they wouldn't have thought to bring it up to date, but I can understand it given that the writer definitely wouldn't have been a child when it was a thing.
Early Simpsons is full of stuff that's bizarrely out of date. Not just the mumps thing, but also the Simpsons having a phone number that starts with KLondike, which was a thing that was phased out in the 60s. And the video game system Bart plays looks like a mid 80s atari, despite the show being contemporary with at least the NES and Genesis
"You son of a bitch. Good show!"

Quick google says MMR came out in 71
Ah yes, Bart's dog is like his owner. My ex had greygounds and they are sleep 99% of the day and speed the remaining 1%

The KLondike thing was so strange!!
