Extended Data Fig. 4: Humoral immunity to measles virus and varicella-zoster virus in older adults.

Antibody titers towards measles virus (MV) and varicella-zoster virus (VZV) in the elderly cohort (51 participants as in Fig. 1) determined at day 0 (before receiving the first dose of the BNT162b2 mRNA vaccine). Each symbol represents one donor. Blue dots indicate aged responders, red triangles low/non-responders to the SARS-CoV-2 spike glycoprotein. Horizontal lines indicate medians, dashed lines indicate the cutoff for antibody positivity at 150 mIU / mL for MV-specific and 50 mIU / mL for VZV-specific IgG. Time p.p.v., Time post primary vaccination.
