It seems like we have had certain diseases under control for long enough that people don’t remember (or never knew) how awful they were. My mom was a nurse in a polio ward. We grew up knowing how terrible polio was … and what a godsend the vaccine was. She was a huge proponent of vaccinations as they became available - she worked for a pediatrician after leaving hospital work. I find it sad that too many people don’t understand how vaccines have helped us.
