This chart shows which Biden Cabinet members have had Covid. Lloyd Austin, the Secretary of Defense, and Xavier Becerra, the Secretary of Health and Human Service, have each had it twice.
Joe Biden, Jill Biden and Kamala Harris have each had Covid. Donald Trump and Hillary Clinton have had it.
There is a non-trivial chance that a Covid infection will result in organ damage, including brain damage, even if you’re vaccinated. Read Lambert Strether’s article for details.
I don’t rule out the possibility that brain damage is already occurring at high levels of government. This is not sarcasm (well, not completely).
Will “Living With Covid” Even Be Possible? (Because What About the Brain Fog)? by ‘Lambert Strether’ for Naked Capitalism. Strongly recommended.
