Coronavirus antibody ‘short-lived’: research

A research article published last Thursday in Nature Medicine states that antibodies or protective proteins made in the body in response to a coronavirus infection can only last two to three months; Especially among people who have been infected but have not shown any symptoms.

This does not mean that these people can be attacked a second time. Because, according to several experts, even if a small amount of strong antibody is made, it can provide protection in the future. In addition to antibodies, the body's immune system has T cells and B cells to fight against the virus.

However, the authors of the article warned that it would not be right to think that anyone would get an 'immunity certificate' as soon as he recovers from Kovid-19.

Antibodies made to the body are thought to last up to a year when infected with other coronaviruses, including the virus responsible for SARS and MARS. Scientists hope that the antibodies to the new coronavirus responsible for Covid-19 disease may last at least the same time.

Several previous studies have shown that most of the Covid-19 patients who showed symptoms developed antibodies in their bodies. However, it is not clear how long these antibodies last.

The new study looked at the body's immune response to coronavirus in people who were infected but did not show symptoms.

Studies have shown that infected but asymptomatic patients spread the virus. And they can spread the virus longer than those with symptoms.

However, Dr. Rasmussen and other experts say that although asymptomatic patients are more likely to spread the virus, it is not clear whether the virus is capable of infecting others.

"It is important for asymptomatic patients to know if they are spreading an infectious virus or just a remnant of a dead virus," said Akiko Yawasaki, a viral immunologist at Yale University.

Dr. Iwasaki attaches great importance to the two new studies. “These articles highlight the need to develop a stronger vaccine,” he said. This is because the immunity that develops naturally during the course of the infection is less than the required level and lasts less time in most people.

According to him, it is not expected that everyone will naturally develop immunity against the virus.
