Figure 3. — Forest plots of mRNA ve against severe COVID-19.

VE data against severe COVID-19 are shown. BNT162b2 and mRNA1273 mRNA VE were evaluated at least seven days after the second vaccination. Severe COVID-19 was defined as hospital admission with the exception of the *Chon et al study which defined severe COVID-19 as death. Circle symbols represents data for young adults (<65 years of age) and triangle symbols represents data for older adults (≥65 years of age). VE: vaccine effectiveness, CI: confidence interval.
