The omicron mutant continues to spread widely around the world, with health officials and authorities expressing concern about the astonishing rise in the infection rate.

In this report, “Al-Shorouk” answers the question, “Is it possible to achieve lifelong immunity against Covid-19?”, as published by the “Times of India” website.

• How does the body remember the virus?

Studies have shown that people who recover from the Corona virus develop a strong immune response to the virus, which in turn protects them from infection again in the future, and this indicates that the body’s immune system is able to remember the virus.

The human body has two main lines of defense, the innate immune and the adaptive immune, and the innate immune response is the first line of defense that begins early when the viral particle is recognized, and this continues to stimulate the host cell to release a protein that hinders virus replication, or it can include The immune system to try to stop the cells at risk.

On the other hand, the adaptive immune response takes longer to provoke a response, because the immune system must first recognize the invading virus before starting a specialized attack, however the adaptive immune system is slow and it can take several days before B cells and T cells can play their roles .

Once the virus is detected and eliminated, memory T and B cells are formed, which remain dormant until they come into contact with the same pathogen, not only recognizing viral particles faster, but also producing stronger interactions, providing long-term protection.

• How is Omicron different from Delta or other variants?

Viruses are programmed to mutate and new variants must appear from time to time, and these new variants may differ from the original strain in terms of mutation and risk.

So, given that the omicron variant contains more than 30 mutations in the spike protein itself, the scientists said it could evade vaccine-induced immunity, and thus could spread at a rapid rate.

Compared to the delta variant, which is said to have led the second wave of coronavirus in India, the new variant is four times more transmissible, but less severe.

• Can the Omicron variant give us lifelong immunity against the Corona virus to serve as a natural vaccine?

Recently, researchers introduced the idea that the Omicron mutant could act as a “natural vaccine”, as Professor Ian Jones, a virologist at the University of Reading, recently supported the idea that it is like influenza, and Omicron does not pose any risks to healthy people, and also mentioned That Omicron can enhance immunity without causing serious illness.
