Abstract

Here we compared SARS-CoV-2-specific antibody and T-cell responses between older adults (>80 years old, n = 51) and a younger control group (20-53 years old, n = 46) after receiving two doses of BNT162b2. We found that responses in older adults were generally lower, and we identified 10% low-/non-responders. After receiving a third vaccination with BNT162b2, 4 out of 5 low-/non-responders showed antibody and T-cell responses similar to those of responders after two vaccinations.
