An interesting question: Has my organism formed antibodies from the vaccine or from the covid infection I have passed?

A new antibody test now makes it possible to distinguish between antibodies formed in the body by covid vaccination or by natural infection with covid-19.

After vaccination, antibodies are only formed against the protein used in the vaccine (i.e. the spike protein and its RBD domain), whereas in an infected person, antibodies are also formed against the "Mpro" and "NP" proteins.

These Mpro and NP proteins can now be detected by a blood test.
