Abstract

Sera of COVID-19 naive vaccinees, COVID-19 recovered cases with vaccination and breakthrough cases demonstrated 1.3, 2.5 and 1.9-fold reduction in neutralization titers against Delta and 1.5, 3.5, 2.8-fold against Delta AY.1 compared to B.1 respectively. However, high neutralization titers would still effectively protect against Delta, Delta AY.1 and B.1.617.3 variants.
