“China has posited that the high rate of mortality in Wuhan was prior exposure to SARS.”
I think there was something about the vaccine for SARS also being a contributing factor - but thought that was tin-foil hat stuff. Maybe not?
You are correct, I did read that there was trouble with the SARS vaccination. It made people worse when they were infected-immune system in overdrive.
It was discovered in time so that the USA knew to shut down the vaccination they were getting ready to roll out.
I can’t recall a lot of the details, and I did not bookmark the articles.
My understanding is the sars vaccine problem, at least in animal models, was well-documented. somewhere I have seen multiple NIH citations on it.
