> Some monoclonal antibodies, including bamlanivimab, lost their ability to bind to the spike protein and no longer neutralized the Delta variant. We also showed that the Delta variant is less sensitive to sera from naturally immunized individuals.
> In individuals who had not previously been infected with SARS-CoV-2, a single dose of either the Pfizer or the AstraZeneca vaccine induced a barely detectable level of neutralizing antibodies against the Delta variant. About 10% of the sera neutralized this variant. However, a two-dose regimen generated high sero-neutralization levels against the Alpha, Beta and Delta variants in individuals sampled at week 8 to week 16 after vaccination. [0]
