patients seem to produce antibodies well

According to the latest data, the majority of patients (up to 99%) with Covid-19 produce antibodies during the first two to three weeks of the disease. It remains to be verified that these antibodies are effective, and that they provide lasting protection from re-infection.

In a pre-publication (still not validated for publication by experts external to the work), New York doctors note that more than 99% of people whose Covid-19 diagnosis has been confirmed by PCR do produce antibodies. To obtain this result, they tested more than 1,300 patients who suffered from mild or moderate Covid-19 (only 3% of severe forms). They used for this an ELISA type detection test which they had even developed and described in a previous pre-publication. According to the team, this test would have a sensitivity of 92% (only 8% of false negatives) and a specificity of 99% (only 1% of false positives). This type of test makes it possible to determine that the quantity (or “titer”) of antibodies is sufficient to act against the virus. “Data-reactid =” 26 “> This is called seroconversion: this is the moment when, face to an infection, the organism starts to produce antibodies directed against it. “After infection, antibodies (…) develop in the days or weeks after the onset of symptoms in most infected people“, explain experts from the CDC (American federal agency for health protection) in a letter to JAMA.

Problem: detecting antibodies is a first step, but to be truly protected from reinfection, they must be able to precisely target the virus and n[…]
