Staying ahead of an evolving virus, health experts say, could prove crucial to permitting schools, businesses and other establishments to reopen and to easing other pandemic restrictions.
Covid-19 vaccines from other companies have shown reduced efficacy in studies in South Africa, and Moderna's vaccine had a more muted effect against the variant in lab tests." [1]
