Since 1980, we've developed vaccines for:

   - Hepatitis B,
   - Chicken Pox,
   - HPV,
   - Rotavirus,
   - Hepatitis A,
   - and Pneumococcal.

There's also been a lot of improvements in existing vaccines, regular new Influenza strain vaccines, etc...

A lot of those simply got quietly introduced into the routine vaccination schedule for children and the diseases quietly vanished without much fanfare in those countries.

Polio is almost eliminated world-wide now, but that's taken decades.

That's uplifting to know! I've had several of those vaccines, but I didn't realize that they were developed so recently.
