I think it is a long dispute here. I don't wanna contribute to debate about the efficktemcy and effectiveness of vaccines.

I posted about Katalin Karikó, who, - as I know - was the first who become known about working out a vaccine, and she is Hungarian.

BTW: my brother is world famous biologist (publicates many times in Nature and Science), and he has some deeper knowledge about this, and I discussed about the pandemia with him, and other friends of mine who are professor of medicine. Nobody was against vaccination, nor declined that the Ckvid is exists.

On the other hand I have seen statistics about statistics both side.

About Sweden we have information about there is no natural immunity against the virus and Swedish leaders was wrong about anti-vaccination.

Many of my friends died from complication of Covid. And they was against vaccination. And only one of my vaccinated friends died, all others survived.

And about the immunity: the black death (the pest) claimed the 1/3 of human population worldwide (of course w/o vaccination). But tt was bacteria not virus

There is no human immunity against AIDS too.

So there is no natural human immunity even not formed immunity against all infection caused by virus or bacteria without vaccination. E.g. every human must have vaccinated against blackpox, polio and so on.

BTW: there is about a debate about origin of Covid, e.g. it is an artifical biological weapon, and developed by US or develkped by China. Ot ks all the same, this pandemia was pandemia.

A hundred words have the same ending the original post was not for or against vaccination.

And with the majority of the human people I also respect the Hungarian Katalin Karikó's work against the Covid.

And nobody knows nothing about "what-if" scenarios.
