Many people will get a low number of antibodies after the vaccination, however, this does not mean that the vaccine does not work, said to KYPE the Associate Professor in the Pharmacy Program of the University of Nicosia, Dr. Christos Petrou, who clarified that many of the antibody tests performed are not specific for measuring antibodies that develop after vaccination.
Asked by KYPE to comment on reports of zero antibodies after vaccination, Mr Petrou said there was a misunderstanding with antibody tests, explaining that many of the antibody tests performed are not specifically to measure the antibodies that develop. after vaccination.
As he said, “vaccines only give antibodies to the cronovirus spike protein, but in addition to the antibodies, there are also T cells that grow.”
“So it's not just the antibodies that are there to see if the vaccine works or not,” he said.
Answering a question about antibody tests performed after infection with the virus, Dr. Petrou said that the specific tests are different.
“My suspicion is that the tests that are done in some chemistry are the antibody tests after they have become ill and not the special tests that are done after the vaccination,” he said.
He clarified that if the antibody index is low after a vaccination, this does not mean that the vaccine did not work, since he noted that it is not only the antibodies that give the body the defense.
He also said that in each person the period when antibodies will develop is different, to add that there is no optimal value to compare the degree of antibodies.
He also said that “it can happen after the vaccination to have zero antibodies and no time can be determined for the development of antibodies.”
He further added that some antibody tests are being performed, however, adding that “they are not specific to detect antibodies after vaccination”.
When asked how long they want to develop antibodies, after the vaccination, Dr. Petrou stated that “this is not constant in every person” and that “he definitely wants some days to start”.
“The studies,” he said, “are not done to measure the number of antibodies, but to see the reduction of symptoms and the reduction of hospitalizations. “The measurement of antibodies is not a reassuring factor.”
Asked if there would be a percentage of the population that would be slow to develop antibodies and if so in this case if it would be difficult to obtain immunity of the population, Mr. Petrou said that there would definitely be a percentage of the population that would be delayed develop antibodies, however, stressed that “it is not only antibodies that play a role in the body's defense”.
