I think the people who have extended CoronaCOVID haven’t developed sufficient antibodies to get well. That’s my view and I’m welcome to it. I also think that not all antibodies are perfect and some are even defective.
I wonder if the corona/COVID-19 vaccine will cure people who are carriers of corona/COVID-19 virus? Injecting them with antibodies might help to fight the virus they have in their system of which they are unaware. That’s a good reason to get everybody tested, whether they have symptoms or not.
How long is a carrier of the coronavirus/COVID-19 a carrier?
