The Moderna vaccine showed similar results in its clinical trial, with an efficacy of 94% against disease at the time of emergency use authorization. Johnson & Johnson, which partly tested its vaccine in South Africa when the beta variant emerged, reported an efficacy of 66% in preventing moderate to severe COVID-19 and an efficacy of 85% in preventing severe or critical COVID-19.
