Johnson & Johnson is beginning a huge final study to try to prove if a single-dose COVID-19 vaccine can protect against the virus.

A handful of other vaccines in the U.S. — including shots made by Moderna Inc. and Pfizer Inc. — and others in other countries are already in final-stage testing. Hopes are high that answers about at least one candidate being tested in the U.S. could come by year’s end, maybe sooner.

U.S. health officials insist the race for a vaccine isn’t cutting corners.

“We want to do everything we can without sacrificing safety or efficacy — we’re not going to do that — to make sure that we end up with vaccines that are going to save lives,” Dr. Francis Collins, director of the National Institutes of Health, told reporters.

But many vaccine specialists question whether the Food and Drug Administration will stick to that goal under intense pressure from the Trump administration. President Donald Trump has consistently presented a faster timeline for a new vaccine than experts say is adequate to fully test the candidates.

Trump on Wednesday tweeted the link to a news report about the Johnson & Johnson study and said the FDA “must move quickly!”

Meanwhile, testing of still another experimental vaccine, made by AstraZeneca, remains on hold in the U.S. as officials examine a safety question, even though studies have resumed in other countries. ...
