The 95 COVID-19 participants included 15 older adults (ages 65+) and 20 participants identifying as being from diverse communities (including 12 Hispanic or LatinX, 4 Black or African Americans, 3 Asian Americans, and 1 multiracial).
In addition, Moderna said a review of solicited adverse events indicated that the participants tolerated adverse events from the COVID-19 vaccine.
The majority of adverse events include fatigue (9.7%), myalgia (8.9%), arthralgia (5.2%), headache (4.5%), pain (4.1%), and erythema/redness at the injection site (2.0%). The adverse events were mild to moderate and were generally short-lived.
In a statement, Moderna CEO Stéphane Bancel said, “This is a pivotal moment in the development of our COVID-19 vaccine candidate. Since early January, we have chased this virus with the intent to protect as many people around the world as possible. All along, we have known that each day matters. This positive interim analysis from our Phase 3 study has given us the first clinical validation that our vaccine can prevent COVID-19 disease, including severe disease.”
