Neutralization of P.1 by vaccine serum

(A) Pfizer vaccine. Serum (n = 25) was taken 7–17 days following the second dose of the Pfizer-BioNTech vaccine. FRNT titration curves are shown with Victoria, B.1.1.7, and B.1.351 as comparison (Supasa et al., 2021; Zhou et al., 2021).

(B) AstraZeneca vaccine. Serum was taken 14 or 28 days following the second dose of the Oxford-AstraZeneca vaccine (n = 25).

(C and D) Comparison of FRNT50 titers for individual samples for the Pfizer and AstraZeneca vaccine among Victoria, B.1.1.7, B.1.351, and P.1. The Wilcoxon matched-pairs signed rank test was used for the analysis, and two-tailed p values were calculated. Geometric mean values are indicated above each column. Relevant data are shown in Table S5.
