If you havegot the Covid vaccineThere may be a small voice in the back of your head by saying, "What if it did not work?" Disease and Prevention Control Centers (CDC) reported cases of revolutionary covidationhave infected people Who were fully vaccinated - and while the risk is very weak, it is normal to feel a little worried. You can also be worried if you already have a compromised immune system or if you have not experienced part of theCommon side effects reported after vaccination. But do not go for an appointment for an antibody test to try to see if the vaccine produces sufficient antibodies to protect yourself from coronavirus. Experts say that antibody tests can not tell you if your Covid vaccine has worked - and there are essential reasons.

The CDC does not recommend thatYou use antibody tests "Evaluate immunity" in Covid after vaccination. According to the agency, most COVID antibody tests are looking for antibodies different from those produced by Covid vaccines available: Moderna, Pfizer and Johnson & Johnson. The antibody tests that do not detect the specific antibodies induced by these vaccines "will be negative in people without history of the previous natural infection", even if they have received one of the three vaccines.

"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."

Carl Fichtenbaum, MD, an infectious disease specialist at the University of Cincinnati College of Medicine, told NPR that there are actually reliable antibody tests toCheck antibody protection Vaccines for other diseases, such as mumps and measles. However, he noted that "those who took decades to develop and with COVID-19, we are only of the year and a half," which means that scientists did not have time to develop a Also reliable antibody test for COVID vaccines.

According to Ostrosky, if you are determined to test your immunity, there is a test that scientists produce to test antibodies for COVID vaccines created: an anti-covidation antibody test of the SPIKE protein. You can try to search for one of them two weeks after your final dose of the Covid vaccine, but Ostrosky also notes that the experts still do not know exactly what correlation exists between the level of these antibodies and your real immunity to the coronavirus .

In fact, the diagnoses of the quest, one of the manufacturers of an American administration and the administration of food and drugs (FDA) - Spike Covid protein antibody test, indicates that its 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.

"If you are tested for antibodies and that the results are low or without all, that does not mean that your vaccination has not worked," said Ostrosky. "You should talk to your doctor about your results."
