Vaccines and anesthesia are the two of the most important life saving/extending discoveries ever. It is truly unimaginable to be pulled backwards like this.
It's funny how vaccines worked so well that now infant mortality is low enough for all the new generations to forget it was ever a common thing.
Vaccine stability has made us forget why it was so important in the first place.
Before vaccines, 450 children died out of every 1000. Now? 20.
