Johnson & Johnson on Saturday became the third developer of a COVID-19 vaccine to be granted an emergency use authorization (EUA) by the FDA, allowing patients to be dosed with the company’s Janssen COVID-19 vaccine candidate—more than two months after the agency granted the first two.
The first four million doses of its Janssen COVID-19 vaccine are expected be distributed across the United States this week, with 100 million doses set to be delivered by the end of June. Unlike Pfizer and BioNTech’s BNT162b2, which received an EUA on December 11, and Moderna’s mRNA-1273, which was authorized for emergency use a week later, J&J’s vaccine requires only a single dose.
