Figure 2.

Reciprocal PRNT titers representing 80% neutralization (PRNT₈₀). ChAdOx1 Chik and ChAdOx1 Chik ΔCap vaccines induce neutralizing antibody titers comparable to those induced by 181/25. PRNT titers on day 25 post vaccination. Horizontal dashed line represents the limit of detection (LOD) of the assay of 20. All values recorded as 10 had neutralization values < LOD. Dots represent titers for each animal; bars represent means and SEMs. One-way ANOVA with Sidak’s multiple comparisons test; * p < 0.05; ** p < 0.01.
