Before my first vaccine dose I asked a former student (who admitted Mt Sinai's first case, and watched countless patients die) about my vitamin D and Clemastine regimen. I didn't want to interfere with the vaccine. "No good deed goes unpunished!" is a bromide, that I was worried about here. "Correlation does not mean causation" is standard statistical caution. She advised me to stop the Clemastine, despite no news whatsoever about its effects after the initial study I'd read, just in case it did work. She advised me that my Vitamin D was irrelevant, that the prevailing consensus was that Vitamin D deficiency identified individuals at risk, but that taking Vitamin D didn't alleviate the correlated risk factors. (On the subject of statistical reasoning, I'm not one for conspiracy theories. Conspiracy fatigue is however just as real as COVID fatigue. Even the LA coroner said RFK was shot point blank from behind, but after JFK... Still, a bat virus lab in Wuhan? I don't know about causality, but that's a pretty choice correlation.)
