Medical care has increased tremendously since the mid-60’s.
Addressing viral or bacterial meningitis with antibiotics, antivirals, and anti-inflammatories, would prevent a lot of cases of blindness and deafness.

Plus, I have never met anyone who went blind or deaf from measles. How many do you know?
You’re wasting your time. I would not be surprised to read a claim downthread that rabies isn’t fatal.
