Immunity Associated with SARS-CoV-2

The IASO Study

​IASO, the Greek goddess of recuperation from illness

The IASO study investigates SARS-CoV-2 immunity in vaccinated and naturally infected individuals.

Since October, 2020, 3,375 employees and health care workers at the University of Michigan have participated in the IASO study, helping us learn more about SARS-CoV-2 immunity, reinfection, and virulence.

SARS-CoV-2 Assessment of Viral Evolution program (SAVE)

IASO contributes samples to SAVE, a project created by NIAD.

SAVE’s ongoing mission is to identify and monitor variants of SARS-CoV-2. The project also examines the effectiveness of vaccines and natural immunity when our bodies are exposed to new SARS-CoV-2 variants, a critical part of fighting the pandemic.
