COVID did not like smokers.
I saw an article where one group that was pretty much immune to COVID were smokers. Smokers maintain a level of nicotine in the bloodstream. Smoking blocks the spike protein.
Now this isn't a call for folks to start smoking, but the article suggested the Nicotine patch for those who suffer from Long COVID.
