Numerous COVID Vaccines are 100% Effective at Preventing Death

Of all the possible outcomes from COVID infection, clearly death is the one we want to prevent above all. We commonly see vaccine efficacy numbers from the 60’s to the 90’s, but that figure generally refers to how successful the vaccine is at preventing a COVID infection with any symptoms.

How effective are the vaccines at preventing you from dying of COVID? Turns out, regardless of whether you look at trial data from Pfizer, Moderna, AstraZeneca, Johnson & Johnson, Novavax or the Russian Sputnix V vaccine, you don’t see a single COVID death.

I came across this information in fascinating Twitter thread today from the eminent Yale virologist Dr. Akiko Iwasaki:

This is a simple and highly relevant message I’d like to see broadcasted far and wide…vaccinated people don’t die of COVID. Period.

What is Quercetin and Can It Protect You Against COVID?

At first, I couldn’t even spell it! I first heard about quercetin in this interview with Dr. Mark Gordon, and was intrigued that an over-the-counter supplement might help protect against COVID and even colds and flus. But I was a little skeptical, so I decided to do some digging.

I found this widely cited study which concluded that although we can’t say to a certainty that quercetin can protect us from COVID, there is some good evidence for it, especially if taken with vitamin C. What’s more, the risks seem quite low:

Quercetin displays a broad range of antiviral properties which can interfere at multiple steps of pathogen virulence -virus entry, virus replication, protein assembly- and that these therapeutic effects can be augmented by the co-administration of vitamin C. Furthermore, due to their lack of severe side effects and low-costs, we strongly suggest the combined administration of these two compounds for both the prophylaxis and the early treatment of respiratory tract infections, especially including COVID-19 patients.

The study authors are careful to note that this is an “experimental strategy,” and I found another study that questioned whether using quercetin to protect against COVID is well-founded.

That said, given the reasonable cost, low risk, and emerging evidence of efficacy, I decided to order some here. I’ll take it in conjunction with the vitamin C and vitamin D I already take and hope for the best!
