Beta-containing COVID-19 booster vaccine found to cross-neutralize variants in non-human primates

A new paper presents preliminary evidence that a new vaccine candidate, designed to boost immunity in already immunized individuals, and containing the adjuvanted Beta spike variant protein antigen, can induce a potent cross-neutralizing antibody response in non-human primate models that is detectable for up to three months.
