dr.schliemann: This virus, like the others of the
Coronaviridae family, seems to be able to mutate very quickly.
A study tracked back the origin of the infection present in Italy thanks to genome analyses and it proved that the virus probably came from southern Germany because the italian and german viruses genomes share some mutations not present in the chinese strain.
However, after the first infection, the immunity system should be able to identify the virus, at least to certain extent, even in case of mutation: that's what happens with the seasonal flu. In other words supposition of Johnson's scientific advisor is probably that, after a cycle of contagion, SARS-CoV-2 could become similar to the seasonal influenza or wishfully vanish as previously happened to the first SARS-CoV.
I agree that there seems to be a lot of assumptions and speculations in this strategy and I think it's very hard to tell what's going to happen.
I've turned this all in my mind and given all the variants involved, this 'great idea' is like playing apprentice sorcerer, which I find greatly disturbing if not criminally insane. That's the kind of thing that's most likely to keep me up because I've never liked the idea of someone playing Russian roulette with my life and countless others.
All Europeans/US/Canadians people etc living here who know of this, probably are too in a very rattled frame of mind...
