Marija Gnjatović, a guest on the Belgrade Chronicle, pointed out that those with antibodies should also think about vaccination.
– Certainly, they shouldn’t be on the front line of giving the vaccine because they have some protection, but when there are large quantities of vaccines available, we should think about immunizing those people as well – Gnjatović points out.
It says that more than 90 percent of people develop antibodies and that only a small percentage of them disappear after a few months. According to our estimates, less than three percent of people do not develop an antibody response, but most of the time they are people with very mild or absolutely no symptoms, “explains Gnjatović.
He says that asymptomatic cases also develop antibodies, but somewhat lower values. He notes that rapid coronavirus antigen tests are reliable only a few days after symptoms appear.
– Antibodies develop on average around the fifth day after the onset of symptoms. It is a class of IgM antibody. It appears first and indicates the acute condition and the presence of the virus. Around day 10-14, the class of IgG antibodies is formed, and these are the antibodies that protect us and remain in the body for months – explains Gnjatović.
He says there were cases where measurable amounts of antibodies were formed even before symptoms appeared.
– The response is individual, it depends on many factors – the amount of virus that infects the patient, the body’s defenses, the general condition … The days on which the antibodies appear vary, but we can be sure that two weeks after the onset of symptoms are already present in blood samples – notes Gnjatović.
Marija Gnjatović says that 20% of the people were in contact with the virus, and most of them did not even know they had had contact and were lying down.
– We are not yet close to herd immunity and I am afraid that it will not be acquired without mass vaccination – says Gnjatović.
Believe that nothing bad can happen when someone gets vaccinated.
– Vaccines have been tested. It hasn’t been as long as we are used to. Not several years have passed since the vaccine was made, but everything was done much faster because the situation demanded it – emphasizes Gnjatović.
It is not yet known how the antibodies will react to the new strain of the virus. Marija Gnjatović says that viruses constantly mutate in nature, but that she is a bit concerned about the emergence of new strains of coronavirus.
– These are the expected reactions. The virus is trying to survive in the population. Even a vaccine can be the cause of the virus mutation, explains Gnjatović.
Point out that this virus doesn’t even mutate as fast as others.
– There are usually neutral mutations that do not affect the speed of spread, or the development of a more serious clinical picture. This strain has been determined to spread faster and that can create a big problem for health systems, warns Gnjatović.
He says there is no scientific evidence yet for how the virus mutates.
– It is only known that the mutation originated in that protein that is very important for the virus to enter cells, but it is not yet known how the antibodies created to the new strain will react, or how the vaccines will work. They are supposed to be efficient – says Marija Gnjatović.
