They then exposed these samples in a lab to engineered pseudovirus particles that contained mutations in the "spike" region of the coronavirus, which were particular to either the B.1.617 or B.1.618 variants, first found in India. The Moderna SARS-CoV-2 vaccine booster developed specifically with variant B.1.351 in mind shows efficacy against that strain and the P1 variant among people already vaccinated for COVID-19, according to first results released on Wednesday.
