When I was a little boy (only last week!) my dear late parents had me vaccinated against smallpox, polio and cholera. (Despite my being so young and so long ago ... last week! ... I recall that cholera shot really made me unwell.)

Anyway, the whole concept of a "booster" for a vaccine never existed until a year or so ago. A proper "vaccine" does not need any "booster". You have immunity and that is that. It is the whole point of vaccination. No one ever suggested I needed a "booster" for polio/smallpox/cholera. (Which, by the way, can actually be quite nasty if you get them.)

How did we go from a totally novel and bizarre innovation of "booster", to its repeat several times over?

And all this for a virus largely harmless to the vast majority of healthy people?
