Neutralizing antibody

The virus continues to change, the new variant attracts attention with its large number of mutations - over 32, for comparison the Delta variant has only 16. It is located in the spike, it can run away from the immune response, neutralizing antibodies are directed against the spike. This should not cause panic. This was stated in "The Day Begins" by Prof.

"People with antibodies who have suffered but are not listed in the Unified Information System can be tested in certified antibody laboratories and, if they have them, also receive a green certificate, this is my opinion," told BNR Professor Margarita Apostolova from BAS - Institute of Molecular Biology.

Antibodies formed after coronavirus disease fade rapidly. The tests are not reliable enough to know if their number is protective - ie. enough to protect us from a new infection. So there is no point in doing antibody tests.

In The Day Begins, Bulgarian virologist Prof. Radka Argirova commented that there is a difference in the antibodies that our immune system builds up after natural infection and after immunization.

Vaccination produces a specific type of neutralizing antibody in the body that is effective in dealing with the coronavirus.

These are questions many people gone through coronavirus wondering about - how do we know that are we protected from Covid-19? Vaccinated  are also wondering whether they are already immune to the virus.

Antibody tests may have many answers and can help with all of these questions, although they don't provide absolute clarity about levels of immunity.

The Pfizer and Moderna COVID vaccines should remain highly effective against two coronavirus variants first identified in India, according to new research carried out by U.S. scientists.

The lab-based study was carried out by the NYU Grossman School of Medicine and NYU Langone Center and is considered preliminary because it has not yet been published in a peer-reviewed journal.

"At the moment, there is no evidence that the new strain of coronavirus, discovered in the UK, makes the vaccine meaningless, because the vaccine, like the natural disease, leads to the formation of neutralizing antibodies and cellular immunity. " said, Head of the Department of Infectious Diseases at the Medical University in Sofia.
