I had the measles as a kid. I remember everything I ate tasted horrible except soup. The light hurt my eyes and I was very tired. Other than that it didn’t last long.
Measles, among an unvaccinated population, would make Covid look like a Sunday walk. But we actually came up with a vaccine that stopped it dead in its tracks.
The measles isn’t a coronavirus. It doesn’t mutate every time it reproduces.
Real vaccines tend to be good for the population.
I was 4 when my slightly older brother and I were sick with the measles. We were quarantined together, and only mom was allowed to bring us food and take our temps, etc. Like you, I remember light hurting my eyes. All I did was sleep for days. I remember I felt like crap. When I finally was better, I woke up to find my brother playing already. Maybe he got it first. I tagged along with him at every opportunity those days. I’m sure I was a pest. I do think Mama made us fried chicken when we were well enough to eat more than a few bites of food. Mmm, mmm, mmm, her fried chicken was the BEST!
