Note again this can only arise during a COVID-19 case, 'natural infection'.
All leading vaccines use stabilized Spike, so the vaccines cannot do this.
For a medical audience, the main conclusion from this is more evidence in favor of APS as a contributing factor in severe COVID-19 thrombosis and pulmonary edema.
For a non-medical audience, the main conclusion is to try to get a COVID-19 vaccine ASAP.
In the meantime, keep in mind there is extensive clinical evidence that early antiviral treatment (including prophylaxis) reduces risk of progression to moderate or severe COVID-19.
The things we are discussing about 5-HT2 antagonists and plasma serotonin, about attempting to halt progression in the early severe stage, are relevant *during* these events.
Rates of PTSD following survival from severe COVID-19 exceed 30%, ditto anxiety and depression.
The ventilator settings required to keep these patients alive tend to permit blood CO2 levels to rise somewhat, in avoiding excessive mechanical damage to the lungs.
This has been repeatedly demonstrated to cause severe anxiety and promote PTSD.
