On August 18, 1965, Dr. Anan Chongkaewwatana, a virologist Director of Animal Health and Management Innovation Research Group National Center for Genetic Engineering and Biotechnology (Biotech), National Science and Technology Development Agency (NSTDA) posted a message via Facebook Anan Jongkaewwattana stated that …
People who have been vaccinated against COVID and accidentally get infected If recovered and without symptoms of Long COVID, it is considered a lucky person. Because the immune area from the vaccine does not reach the upper respiratory tract or in the nose, we will receive a natural landscape. And because the nose is the part of the body that is the starting point for infection and multiplying the virus, the immune system is ready to fight. The acquired landscape will help us fight the next re-infection. even if it can happen again The increase in the number of viruses will not be as much as before.
After infection, besides our nose, there are IgA antibodies waiting to catch the virus in the nose. A recent study by the Singapore team compared the cells in the nasal membranes of vaccinated people and those who had been vaccinated. People who have been exposed to the real virus in the nasal area have white T cells that recognize a variety of viral proteins. that is not limited to only protein spikes These white blood cells, if found again in cells with a recognized protein, will destroy it, giving the virus time to multiply as much as it did before the location in the nose itself. The research team found that among the proteins recognized by the T cells in the nose, and the largest number is The protein is called Nsp12, which is not present in any vaccine formulation. Without infection, we would never have known T cells for this protein. What matters is that no matter how the virus mutates and escapes, Nsp12 appears to be very dormant. does not change like Spike So what the T cell remembers will still work.
Unfortunately, the T cells in the nose after infection decline over time like antibodies. The researchers found that T cell levels remained unchanged three months after infection, but at six months their levels had dropped by more than half. This may be the reason why people who have been infected with the infection have symptoms after being infected for a long time.
