Resistance to Covid-19 infection remains for at least five months

Resistance to Covid-19 infection remains for at least five months, investigators reported — and probably lengthier than that.

While the study may seem perplexing and contradictory to a comparable report out of Britain this week, it is not. People’s bodies generate an army of immune substances in response to an infection, and many are complicated at first, succumbing off quickly, while others develop more gradually.

The new account out Wednesday reveals 90% of men and women who recover from #Covid-19 infections maintain a stable antibody reaction.

British study demonstrates proof of subsiding immunity to Covid-19.

Although some researchers have suggested antibodies to this virus go away rapidly, experts have found just the reverse — that more than 90% of individuals who were moderately or averagely ill produce an antibody response strong adequate to counteract the virus, and the response is preserved for countless months.
This is important for successful vaccine improvement.

Can one get infected with Covid-19 two times? It is challenging
The team examined the antibody responses of more than 30,000 people who tested positive for Covid-19 at Mount Sinai’s Health System between March and October. They characterized their antibody reactions as minimal, moderate, or high. At least 90% had moderate to high amounts, or titers, of antibodies to the virus’s surge protein — the structure it uses to grip the cells it infects.

They then accurately studied 121 individuals who restored and contributed their plasma — once three months after they first produced signs, and again five months later.
