I think you meant “aggravate” a condition and with the millions of doses of the vaxx out there I do believe that for UKNOWN reasons certain people have SERIOUS sensitivities to the spike protein production but No ONE in the gubmint is looking at it.
In terms of deaths per million (aside from Peru) the highest levels are in Eastern (read Russian) Slavic populations.
Biowarfare pointed at Russia? Enquiring minds would like to know.
Oh and the USA, with the most sophisticated medical system in the world is right at the top of deaths per million but that could be the US pushing the vaxx and the medical community being paid big bucks for positive covid admissions.
All this for a flu that 99% would survive and even more if they had some basic vitamins. Sigh.
If it was not biowarfare, then EUAs were trumps abuse of power, to put it mildly.
