The researchers observe a “worrying” decline in antibodies against corona recoverers

It contains the blood of people who are recovering from the epidemic. Antibodies against the virus have shown “plasma” technologies to be of great benefit for the treatment of corona patients.
Doctors say the use of blood plasma reduces the time a patient stays in the hospital due to: Corona complications.

And this week, the American Society of Microbiology’s MBO revealed that the levels of antibodies in the blood of the recovered are rapidly decreasing.

The researchers added that the levels of these antibodies to the virus drop dramatically within weeks after the body gets rid of the virus and the symptoms go away.

Scientists believe that it is necessary to extract this plasma in the short time after their recovery, as according to News Medical it will not be useful if delayed.

In the meantime, recovered corona patients cannot donate blood until 14 days have elapsed after the symptoms have disappeared, so that the body has enough time to remove the remaining virus particles.

Andres Fenzi, a researcher at the University of Montreal, Canada, said, “We don’t want to transmit the virus, but the antibodies, but our work has shown that the plasma’s ability to neutralize virus particles decreases during the first few weeks. ”

Vinzi and other researchers examined samples from 31 people who had recovered from the novel coronavirus. The antibody level was compared after one month.

The researchers then measured the antibodies’ ability to respond to the viral protein, and the results showed that it decreased after a period of 6 to 10 weeks from the onset of disease symptoms.

And Finzi pointed out that these conclusions are very useful because they explain to scientists how the antibodies interact with the virus, and vaccine developers will also benefit because the study gives them an idea of ​​how long immunity lasts.
