A new study out of Germany, funded by the German government, and published in the medical journal Science Immunology, raises the possibility that the so-called vaccine manufactured by BioNTech/Pfizer to fight the mRNA SARS-CoV-2 virus (and possibly the Moderna product), reduces a person’s level of antibodies that fights the virus and increases the level of another kind of antibody that is much less effective at fighting the virus.
