Produce antibodies regardless of age: Breakthrough in new coronavirus research: antibodies will be produced whenever infected

A new study brings a silver lining to the severe challenge of the new coronavirus: almost all patients who have been infected with the new coronavirus will eventually produce antibodies regardless of age, sex or severity of the disease.
Antibodies are immune protein molecules produced by the body to fight off pathogens. Many countries such as the United States hope to use antibody tests to help determine who has been immunized with the new coronavirus and can start working again. Those with immunity can replace vulnerable individuals in highly contagious environments and establish what researchers call “immune shielding” among the population.
The researchers conducted research based on the antibody test developed by virologist Florian Krammer at the Icahn School of Medicine at Mount Sinai in New York. The false positive rate of the antibody test was less than 1%.
The research eased people ’s past worries that only severely ill patients could produce antibodies. The researchers found that even people with mild symptoms can produce enough antibodies; there is no age or gender difference in antibody levels.
The researchers tested a total of 624 people, and they all agreed to be potential donors of restoring plasma (antibodies extracted from their blood).
At the beginning of the test, only 511 people showed strong antibody levels, 42 people had very low antibody levels, and 71 had no antibodies. But more than a week later, when 64 of them who had weak antibody levels or showed no antibodies came back for testing, only 3 had no antibodies, and the others had antibodies to some extent.
The researchers said that this represents the time of testing the antibody sooner or later, greatly affecting the results. Experts say the next step in research is to confirm that antibodies can fight viruses and protect the body.
According to Sean Whelan, a virologist at Washington University in St. Louis, “The question now is how well these antibodies neutralize the virus and protect the body from infection. We believe all antibodies should Can provide immune protection. “
Cramer’s research team conducted a study on more than a dozen people earlier and found that the antibody level is equivalent to the level of neutralizing activity. Kramo said that all people who produce antibodies may have a certain immunity to the new coronavirus. As for how long the immunity can last, it depends on continuous observation.
