Not comparing like with like

From the BBC:

Every year they stop an estimated two to three million deaths, preventing more than 20 life-threatening diseases, according to the World Health Organization (WHO).

Childhood illnesses that were common less than a generation ago are increasingly rare. And smallpox - which killed hundreds of millions of people - has been completely eradicated.

But these successes have taken decades to achieve - and many of us are now expecting effective coronavirus vaccines to have similar results in a radically shorter time frame.

Of course it took decades, because vaccinations against diptheria, whooping cough and measles were just given to young children on reaching a certain age, and it took a few decades before mass immunity against each of these was achieved.

If the UK government and/or NHS get things sorted out and manages to vaccinate [nearly] the whole population within a year, then surely we'll achieve in a year what used to take decades?

Correct me if I'm wrong, but I don't believe that there has ever been a successful vaccine for a coronavirus. Maybe vaccines for respiratory diseases is a bit more difficult?

MB, I am going by what Dr John Campell says on YouTube every day.

He reckons that the disease most similar to Covid-19 is SARS, and people who survived that 17 years ago are still immune.

It is true that these viruses mutate, but apparently this type does not mutate that often, and people who had it a year ago have not caught one of the new strains (or those who did only had a mild case).

Worst case, we all have to go for a booster jab every few years. Not like the annual flu vaccines which are always fighting the last war and seem pretty pointless.

But Dr JC is the expert, not me.

MB, the coronavirus vaccine is a new type of vaccine.
