Even beyond clinical trials, editing research has shown that Moderna, Pfizer and Johnson & JohnsonVaccines against COVID-19 Administered in the United States are very effective against the virus. Other studies have even shown that the shots remaineffective against new variants who started spreading in different parts of the globe. So, if you are fully vaccinated, you can rest that your shots do their job. But if you are in the rare position of not needing to know if your vaccine has actually worked, doctors say that the only way to discover is a specific type of test that is given at the right time.

RELATED:Half of the people who did it that did not have an antibodies after vaccination, the study says.

Instead of a typical quick test, doctors say request a specific laboratory test calledElisa Test at least two weeks After receiving the Moderna or Pfizer vaccine or four weeks after receiving the Johnson & Johnson shot can offer a better look at the spike protein antibodies generated by the doses,The New York Times reports. Indeed, traditional antibody tests are not designed to check the types of markers that the vaccine has led to your immune system.

"When most people register for a [an antibody] test, most laboratories and suppliers generally test forAnti-nucleocapsid antibodies, "Luis Ostrosky, MD, an infectious disease specialist with Physicians from the University of Texas, explained in a blog article for the university. "The problem with it is not antibodies that would be created by the vaccine, but only by a natural infection."

But the experts still emphasize that it is very rare that someone would need to know with certainty the response of their body to the vaccine. "Most people should not even worry about that"Akiko Iwasaki, PhD, an immunologist at the University of Yale, saidThe temperature. "I feel a little hesitant to recommend that everyone be tested, because unless they really understand what the test does, people could get that bad sense of not having developed antibodies."

Nevertheless, Iwasaki stated that your vaccination protects or not, you can be important for immunocompromised people. It cites the example of a transplant patient whose ELISA test shows mediocre antibody levels using the results to convince an employer they should be allowed to continue working at home while offices rely.

But even then, the results of your test may not be as conclusive as you need it. Diagnosis of the quest, one of the manufacturers of an American diet and an administration of medicines (FDA) -AuthorizedSpike Protein Covid Anti-Covid Antibody Test, says that his test can detectAntibodies of an earlier infectionBut post-vaccination results are not certain. "The positive results can also occur after CVIV-19 vaccination, but the clinical significance is not yet known, or the quality of this test of detecting antibodies in those who have been vaccinated", notes the company on their site Web.

Another expert emphasizes that only antibodies are not only a determining factor in the way the immune system has been prepared against the virus, such as a response in the body called cellular immunity. "There are a lot of things under the surface that antibody tests do not measure directly"Dorry Segev, MD, a transplant surgeon and a researcher at Johns Hopkins University, saidThe temperature.
