Absolute and relative vaccine effectiveness (rVE) against hospitalization (point estimates [95% confidence intervals]) for primary series plus first mRNA booster dose and mRNA vaccine primary series alone (overall, 18–64 years and ≥65 years), December 2021–April 2022. The rVE point estimates at the left of each age category are denoted by red dots, absolute vaccine effectiveness (aVE) point estimates in the middle and at the right of each age category are denoted by yellow dots, and 95% confidence intervals are delineated by black vertical lines going through the corresponding dots for each point estimate.
