GAVI CEO says vaccines may not continue to be effective against emerging variants

Seth Berkley, MD says current vaccines have been effective at preventing severe disease and death from newer strains of covid-19 but that may not continue with emerging variants.
“There are variants of interest and there are some scary variants that keep appearing, but we don’t yet understand. There’s a C.1.2 that just appeared in South Africa that may have resistance… There’s a new Mu variant… Up until now, all of the variants… have been able to be protected against severe disease and death by the existing vaccines, but that may not continue.”
