Avidity Maturation of Humoral Response Following Primary and Booster Doses of BNT162b2 mRNA Vaccine Among Nursing Home Residents and Healthcare Workers [PDF]

Infections, despite vaccination, can be clinically consequential for frail nursing home residents (NHR). Poor vaccine-induced antibody quality may add risk for such subsequent infections and more severe disease. We assessed antibody binding avidity, as a
