Corona virus has affected people’s lives, many of them have been infected and some have succumbed to the virus, while others continue to suffer from extended symptoms of corona, and the unpredictability of the virus is now known to everyone, given the fact that corona affects people in a distinctive way depending on age, gender and existing medical conditions In advance, it has become very important to understand how the virus works, whether the body remembers it after infection, and if yes, how and for how long it is protected from it?, which will be presented in the following lines, according to a report by the “Times of India” website.
How does coronavirus infection build immunity?
If you are someone who has previously been infected with the Coronavirus, you can certainly expect to develop a certain level of immunity to the virus. When you are infected with the virus, your body produces an immune response to fight off pathogens, which in turn stimulates your immune system to develop antibodies, protecting you from any chance of infection again. Other.
Although there is no strong evidence confirming the duration of immunity from corona infection, there have been studies that indicated that immunity to corona may be long-term..
Does your body remember the virus?
According to two recent studies, people who recovered from the Corona virus produced a strong immune response that outperformed vaccination alone, and adding one or more doses of the vaccine provides stronger protection..
This only indicates that the body’s immune system, which fought off the previous infection, remembers the virus and provides protection against another bout of corona infection.
How does the body remember the virus?
The human body has two main lines of defense against viruses, i.e. the innate immune system and the adaptive immune system.
The innate immune response begins early when the viral particle is recognized early in the stage. This continues to stimulate the host cell to release a protein that inhibits viral replication or can involve the immune system to try to stop the cells at risk..
On the other hand, the adaptive immune response takes longer to elicit a response, because the immune system must first recognize the virus before a specialized attack can begin. Antibodies are part of the adaptive immune system. Once the virus is detected and recognized, B cells make these antibodies that can It attaches to viruses and prevents them from reaching cells.
How long do antibodies stay from corona infection?
With regard to natural infections, recent findings have indicated that immunity may remain at its highest levels for up to 90 days, and begin to decline thereafter, and in some cases, it has been found to last for longer periods, and may not be applicable to everyone..
However, many authorities have urged people on the importance of obtaining corona vaccines, even if they have recovered from the infection and have a certain level of immunity, while the levels of natural antibodies may provide some protection, the immunity caused by the vaccine can exceed the natural protection and provide immunity It is permanent from the virus and people who are immunocompromised or at risk of re-infection can also benefit from it.
