Added 2nd definition: 2: a preparation of genetic material (such as a strand of synthesized messenger RNA) that is used by the cells of the body to produce an antigenic substance (such as a fragment of virus spike protein)
They must have seen that Politico moron on MSDNC say "antibodies is the new vaccine in the Trump crowd" and scrambled to change the definition to fit the new narrative. https://youtu.be/mS3MMMS2ePw?t=297
