COVID-19 Vaccine

Yes, your "layman" explanation is a quite accurate description. CoronaVac is the Chinese one. I looked into it obviously since that was the one my parents got just yesterday actually. I would assume Americans will come nowhere near it.


I'm not sure which one is the absolute best, CoronaVac reported between 50 and 78% efficacy, which is clearly lower than 90% for Moderna and Pfizer. In a double inoculation scheme, CoronaVac should still work decently enough. So it really all comes up to supply and costs. Which ever one you get, is what your government is able to provide for you, so you take it and that's that I guess (Not to mention that when it comes to developing and poor countries, they are at the mercy of big power politics, and acquiring the vaccine in enough supply has proven no different).

Sinovac, the producer of the vaccine has provided Chile with flu shots for years and they seem to work fine, considering I had read something about 60-70% efficacy for those.

Really, just reaching 80% heard immunity so this damn virus is gone soon should be a good story. We'll see how it goes.
