HOW LONG DOES IMMUNITY LAST IN THE CROWN? The answer is given by research by Serbian scientists.

Since the start of the pandemic, in Serbia, 15,000 people have been tested in INEP laboratories, but not all have tested positive for the coronavirus.

“The antibodies will last between a year and a year and a half, that’s kind of an assumption. What we do know is that for seven months, the longer we follow patients, these antibodies survive in the body, than in patients who have developed high levels of antibodies there is no sudden drop in value, they drop by five percent and for all this it is supposed to last at least a year “, said Marija Gnjatović, associate researcher at INEP, in the program” 150 minutes “of TV Prva.

There are patients in whom, as he explains, the antibodies disappear quickly, they are those who asymptomatically or with a very mild clinical picture exceeded kovid-19 and initially developed low antibody values. Those values ​​have been lowered so that they can no longer be measured, but these patients are certainly protected in some way.

“Antibodies are just one of the parameters of the immune system that participate in defense, there are also immune cells that remember contact with the Sars-KoV-2 virus, so there is some type of protection and whoever comes into contact with it virus, the organism will overcome the disease faster ”. she says.

A few days ago, crisis personnel adopted the rapid antigen test application. According to Gnjatović, it is a test that detects the proteins of the virus, which is in fact a complement to the PCR test.

“It cannot be better than the PCR test, but it can be used for mass testing of a much larger number of samples. On the other hand, when the period in which the virus is in the upper respiratory tract passes, when the PCR or a rapid antigen test can confirm the presence of the virus, the application of serological tests is reached, that is, from two weeks from the first symptoms. The gold standard in the application of serological tests is the test of the propeller made by the INEP institute. We do tests at personal request “, adds Gnjatović.

Rapid serological tests are also used today. They are currently used in kovid dispensaries.
