CAMBRIDGE, Mass. — Moderna, which makes one of the two authorized COVID-19 vaccines, is set to launch a clinical trial of a new vaccine designed to combat a variant of the virus, the company announced Wednesday.
The company says it has produced enough of its variant-specific candidate vaccine, called mRNA-1273.351 to begin testing it in people.
Any change to address variants, which other vaccine makers also are working on, would need to be approved by the U.S. Food and Drug Administration.
In a study published last week, Moderna showed that blood from people who received the current vaccine includes neutralizing antibodies against the major known variants. But only one-sixth of their antibodies were protective against the B.1.351 variant of the virus, which originated in South Africa, and which is the target of its new vaccine.
