They used a similar reasoning as OP.
The huge increase on hospitalization in this month suggests heard imunity might not be possible. Either due reinfection, either because a more agressive variant is infecting people not yet imune.
Reports from region says the number of people with 40-50 years hospitalized substianlly increased when compared with first wave.
This new wave of infections seems to be caused by a new variant called P1, it include both B117 (UK) and E484K (SA) mutations.
This hypotesys is still under investigation, given the lack of genomic sequentialing during the first wave.
Yesterday a paper on this new variant was published (and given a new name).
People should be aware that is unlikely heard imunity will be achieved without vaccination. RNA virus are known to have a high mutations rate, and despite covid having a low mutation rate (given its large rna size), it still mutates a lot. And natural selection will favors the variation that spreads more.
