Marija Gnjatović, a guest on the Belgrade Chronicle, pointed out that those with antibodies should also think about vaccination.
“They certainly shouldn’t be on the front line of administering the vaccine because they have some protection, but when there are large amounts of vaccines available, we should think about immunizing those people as well,” Gnjatović notes.
It says that more than 90 percent of people develop antibodies and that only a small percentage of them disappear after a few months.
By our estimates, less than three percent of people do not develop an antibody response at all, but most of the time they are people with very mild or 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 the IgM class of antibodies. It appears first and indicates the acute condition and the presence of the virus. And they remain in the body for months,” explains Gnjatović.
He says there were cases where measurable amounts of antibodies appeared before symptoms appeared.
“The answer is individual, it depends on many factors: the amount of virus the patient is infected, the body’s defenses, the general state … The days on which the antibodies appear vary, but we can be sure that two weeks later from the onset of symptoms are already present. in blood samples, “says Gnjatović.
“There is no herd immunity without mass vaccination”
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 it will not be achieved without mass vaccination,” says Gnjatović.
Believe that nothing bad can happen when someone gets vaccinated.
“The vaccines have been tested. It has not been as long as we are used to. It has not been several years since the vaccine was made, but everything was done much faster because the situation demanded it”, emphasizes Gnjatovic.
“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 the vaccine may be the reason for the mutation of the virus,” explains Gnjatović.
Point out that this virus doesn’t even mutate as fast as others.
“In general, there are neutral mutations that do not affect the speed of spread or the development of a more serious clinical picture. This strain has been found to spread faster and that can create a big problem for health systems,” he warns Gnjatović.
He says there is no scientific evidence yet for how the virus mutates.
“It is only known that the mutation originated in this single protein, which 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 effective. “says Marija Gnjatovic.
