Inactivated spike proteins translated by in vitro transcribed mRNA vaccines are stabilized in the prefusion conformation by 2P mutations, since proline is the most rigid amino acid. Wild-type spike proteins are structurally different and can bund ACE2 receptors. Face masks work.
Wrong, mRNA vaccines produce memory B and T cell responses against viral antigens. Can you explain B cell-mediated immunity in germinal centers?
