Relative efficacy, safety and immunogenicity of bivalent versus monovalent COVID-19 mRNA booster vaccines: a randomized trial
The relative efficacy, safety, and immunogenicity of monovalent mRNA-1273 (ancestral WA1) versus bivalent mRNA-1273.222 (ancestral plus omicron BA.4/BA.5) boosting have not been studied prospectively where HIV and SARS-CoV-2 seroprevalence are high. CoVPN 3008 (NCT05168813) was a randomized, double-blinded trial in sev...
