More than 33 million people in the United States.CONTRACT COVID Over the past year, and for the many survivors, it means that some protection to be infected again. Research over the past year have shown that people who had COVID generally develop a certain level of immunity against the virusthrough antibodies and other factors potentially long after their illustration of their disease. The issue of the long time has remained a major conflict. Now, new research has discovered answers: about 88% of people who had COVID maintain antibodies for at least 10 months after initial infection.

A study published May 24 inEclinicaldicine, a Lancet newspaper, analyzed nearly 40,000 people who wereInfected by Covid up to 300 days after the infection. LabCorp researchers tested antibody participants that protect against SARS-2-Nucleocapsid SARS-Nucleocapsid and PICS-Nucleocapsid proteins - between 202020 March and 2021 January.

According to the study, antibodies protecting the SARS-COV-2 SPIKE protein lasted the longest at the most stable rate. Nearly 88% of COVID patients seemed to keep high levels of these antibodies up to 300 days or 10 months after their infection. But 68% also showed high levels of antibodies protecting the nucleocapsid protein 293 days after infection.

"Our observation analysis providesAn encouraging chronology For the development of antibodies and sustainability between the American population, "Main authorDavid Alfego, PhD, Senior LabCorp data scientist, said in a statement.

Brian Caveney, MD, Chief Medical Officer and President of LabCorp Diagnosis, said in a statement that, if it were "good news for naturally infected individuals", new research must be made so that scientists can understand whatType and level of antibody Allow protection against reinfection of COVID.

"It is important to note that the presence of antibodies does not necessarily indicate an immunity for this duration. Greater research is needed to discover quantifiable thresholds for the ability of antibodies to fight against the virus-known as the Neutralization capacity - In order to understand how long they can do this work, "said Caveney to Bioworld.

This is why disease control and prevention centers (CDC) always recommends that those who have beenNaturally infected by Covid be vaccinated against the virus. "The experts do not yet know how much time you are protected from becoming sick after recovering from COVID-19," said CDC. "Even if you have already recovered from Covid-19, it is possible - although rare - that you can be infected with the virus that causes Covid-19 again."

However, Caveney said the study gives researchers more information so that they can continue to think about how to get out of the Pandemic of Covid. And this will also allow scientists to make decisions about "future vaccinations and timing of reminder plans," said Caveney.

People under age 65 could maintain positive rates for these antibodies over time, according to the study. Therefore, whether it is vaccinated, naturally infected, or that the two people aged 65 and over can have trouble maintaining antibodies to protect against COVID for a long time, which could be even more need. reminder.
