How long does your immunity last after David-19? Experts Reveal How Long You Stay Safe

A new study by the Institute for Immmology “La Jolla” in California claims that patients cured by the coronary are likely to have a memory of the immune organism, which continues for at least 8 months.

This immunity, in addition to the creation of antibodies, is made up of many other elements.

Temporary immunity is also provided by white blood cells, known as T cells, and B cells.

Combined together, these protective layers allow the immune system to recognize and re-attack the choreography, if that of “captures” again, thereby preventing a new infection.

To assess how long the immunity of Coved-19 lasts through these different layers of the immune system, scientists measured the type of immune cells recovered to coronary patients several months after they were sick.

“Thing provides a huge immune response to this virus, which lasts 6-8 months” - American virologist Shane Crotti, at the Institute for Immmology “La Jolla” in California, which is one of the scientists for the new study.

Some previous studies have suggested that the number of antibodies created by coronary and protecting the body from infection falls within a few months.

Also, according to the study, these antibodies and white blood cells can reduce the role of killer T cells, which identify and destroy infected cells as well as aids that direct B (leucocity) cells into creating new antibodies.

The team of experts measured both types of T cells, B cells and antibodies, on blood samples from 185 people who had recovered from Covid-19.

Nearly 40 of the participants gave blood many times, several more than 6 months after their infection. This enabled scholars to appreciate how immune reactions over time changed.

Their results, showed that the level of the specific T cells of coronary to patients, dropped slightly between 4-6 months, and then remained at stable levels.

“This takes about 1 or 2 weeks to develop antibodies and reactions to T cells after an infection. They then grow to a peak of”- says Alessandro Sete, another immunologist at the La Jolla Institute in California.

The study's results also showed that B cell levels in patients increased during the period of 1-6 months.

The slow rate of the number of T cells and B cells to patients means that those cells will exist much longer in the organism than the time period analyzed in the study.

White blood cells, developed and studied in time because of the infection of other viruses, can remain in the human body for years.

For example, T cells specific against smallpox may take about 10 years to disappear into the body after an infection, while B cells produced to fight the same virus last 60 years.

T cells for SARS, another coronavirus, which has 80% of its genetic code similar to Covid-19, also appears to exist for a long time in the human body.

But scientists need more time available to study the behavior of the virus under different conditions and mutations.

So far there has not yet been a precise prediction of how long a certain person's immunity to the Coronobrus will last, since it has been infected once.
