So, 2nd wave of Corona will mean the non-"vaccinated" will get sick from the more contagious virus, but will benefit from their natural killer cells fighting back.

The "vaccinated" will also get sick from the variant, but the vaccine-generated antibodies will be useless and will take out the effectiveness of the natural killer cells. In other words, according to this guy, they're fucked.

This doesn't look good from any side. Non-"vaccinated" will be blamed for not achieving a herd immunity that was never going to happen anyway. The "vaccinated" will struggle with coming to terms with being fucked over by deranged assholes and fear mongering.
