Extended Data Fig. 1: Avidity 14–45 days after the second and third vaccine.
From: Superior immunogenicity and effectiveness of the third compared to the second BNT162b2 vaccine dose

Scatter plot analysis of avidity levels in HCW equal or above 60 (>59, n=29 biologically independent samples) or below 60 (<60, n= 52 biologically independent samples) years old. The black bar indicates GMT ± 95%CI. Significance between younger and older populations were tested by two-sided Mann-Whitney test.
