The BMJCOVID-19 Vaccination: Evidence of Waning Immunity is Overstated

Evidence is mounting that much of the concern about waning immunity to COVID-19 is overstated and that vaccines provide high levels of protection against the respiratory disease and its variants over the long-term. Immunologically, plasmablast and B-cell response after mRNA vaccination is long-lived and memory B cells increase over at least six months. And in the field, the evidence is that vaccination is doing what it is intended to do: reduce the severity and spread of the infection.
