Jan 9, 2023 · The combination effect seems to provide greater protection than natural immunity on its own (> 90.0%), with no waning ≥ 1 year after infection or > 6 months after vaccination . Relative protection provided by hybrid immunity versus natural immunity was investigated in a meta-analysis.

The analysis reviewed 26 studies that examined protection against reinfection, hospitalization and severe disease caused by omicron.
