a pNTC-Spike vaccinated rabbit sera were evaluated for the Alpha variant (lineage B.1.1.7), Beta variant (lineage B.1.351), and Delta variant (lineage B.1.617.2) in a microneutralization assay at Statens Serum Institut, Denmark. b Sera from pNTC-Spike vaccinated rhesus macaques were evaluated in a plaque reduction neutralization test at BIOQUAL, Inc., USA. The variants tested were dependent on the viral isolates available at each institute. ns: not significant.
