TWiV explains why this season’s influenza vaccine is not protecting against mild to moderate disease caused by H3N2 virus, and that antibody-dependent entry of SARS-CoV-2 into monocytes is a major contributor to severe COVID-19.
Immunity conferred by influenza virus vaccine is short-lived. After immunization with inactivated influenza virus vaccine, serum antibody levels peak within a few months and then decline rapidly. This decline was recently shown to be caused by loss of bone marrow plasma cells, a major source of serum antibodies. Results of a recent study partially address …
Daniel Griffin provides a clinical report on COVID-19, then we discuss decline of virus-specific bone marrow B cells within a year after influenza vaccination, the push to release SARS-CoV-2 vaccines before completion of phase 3 trials, and absence of evidence for infectious virus in aerosols.
