No deaths or unsolicited AEs that led to discontinuation from study vaccine or the study occurred within 28 days. One SAE of community-acquired pneumonia occurred on day 33 at 50 µg mRNA-1273 in the older cohort, resolved on day 58 and led to study vaccine discontinuation.
PE: primary endpoint; (a): to be demonstrated a result must be statistically significant on a primary endpoint (with multiplicity adjustment if necessary);
Study risk of bias assessed for the study primary endpoint(s) or the main endpoints in case of no formally defined primary endpoint(s).
delta: difference in rate or median (if available)
