Herd Immunity?

[cee-dee]

This morning I saw part of a discussion on the BBC news channel about herd immunity between two "experts", one a proponent of herd immunity and the other a detractor.

I understand we can develop some sort of an immunity to some diseases but others can only be defeated by vaccination and/or the complete eradication of the disease.

The Flu vaccine for instance only works against some "varieties" of it which is why we need a jab every year but if a different "variety" just happens to spread, the jab will be ineffective and I wonder if that will turn out to be the same with covid-19?

So, if covid-19 continues to evolve, will we need constant jabs to counteract each new version?

Remember the BCG jab? Didn't we have some sort of test beforehand and if you didn't react, you had the jab, if you had a reaction you didn't get a jab? Those that reacted already had "herd immunity" of some sort?

So, what's your take on "herd immunity" around covid-19?
