> If this were actually true we would see elites and politicians constantly smoking
We'd only see that if the cumulative risk from smoking and maybe-covid was greater than the cumulative risk from vaccination and maybe-covid, and if the marginal risk from vaccination if one were already a smoker was negative.
As is, I expect this is true, but that the harms of smoking outweigh the decreased risk of covid by quite a lot, so this isn't actionable at the individual level, though it may be actionable for research into biological pathways.
