Study Snapshot

The decline in antibody titers observed after SARS-CoV-2 vaccination may reduce protection, but high antibody titers detected by the Roche RBD total antibody assay may not be neutralizing.

PopulationOlder adults (50-71 years)

Sample size24

MethodsObservational

OutcomesBody Mass Index projections

ResultsSocial networks mitigate obesity in older groups.
