Johnson & Johnson’s one-shot coronavirus vaccine is highly effective at preventing severe disease and death from COVID-19, the Food and Drug Administration found in analyses published today.

An international study found the vaccine’s efficacy rate to be 72 percent in the United States and 64 percent in South Africa, where a more contagious variant is spreading. While these figures are lower than Pfizer’s and Moderna’s efficacy rates, the vaccine greatly reduces the risk of hospitalization and death from COVID-19 and could play a key role in keeping the pandemic at bay. In a clinical trial of 40,000 people, no one who took the vaccine was hospitalized or died of COVID-19 after the vaccine took effect.

Plus, the vaccine requires only one shot and does not need special refrigeration—good news at a time when demand for vaccines greatly outstrips supply.

The FDA could authorize the vaccine for emergency use as early as Saturday, with 20 million doses available by the end of March and a total of 100 million doses delivered by the end of June.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
