Spot on. I'm old enough to recall my patents' relief when I got a polio vaccination. There were multiple children on iron lungs among their age-peer friends.

Spot on. I'm old enough to recall my patents' relief when I got a polio vaccination. There were multiple children on iron lungs among their age-peer friends. I grew up in the age of antibiotic supremacy. It's still counterintuitive for me to realize that somebody can now die of a bacterial infection from a scratch. I hope we don't have to return periodically to the bad old days to convince people of the worth of vaccination. edit - missing word
