Makes you wonder why we bothered with a vaccine for measles when good old ‘herd immunity’ would have done.
How did we get on with Small-Pox prior to a vaccine? Maybe it was just the old and ‘economically inactive’ that died?? Or maybe not, that’s why it took 100s of years and a vaccine to get rid of it??
