I just now tried to do a bit of research on the more virulent strain of measles that you are talking about, and can't come up with much information. If I see some research or ideas on this, I may do a future post about it. I know that people vaccinated with the MMR can get atypical measles, which is a worse form of measles.
I'm glad you avoided the HIV vaccine as that is definitely one of the most horrendous.

Thanks so much for your comment!
