Since it is a novel contagion, researchers are still learning more about the virus, the disease it causes and the extent of immunity gained after infection. Even if your test results show that your body had kickstarted an antibody-forming immune response, there is no conclusive evidence that it can provide lasting immunity against the virus. Recent reports have also shown that antibodies against the coronavirus decline rapidly within the span of just 3 to 4 months in some cases.

As per Dr Angela M. Caliendo, who is a testing expert at Brown University’s Alpert Medical School, we don’t really know if a positive test means that you’re protected. Speaking to Deccan Herald, she said, “We don’t really know if a positive test means you’re protected. If you were sick back in March, you probably don’t have antibodies any more; and if you were only mildly sick, you may not have gotten antibodies.”
