Johnson & Johnson Expects Vaccine Results Soon but Lags in Production

 

The U.S. needs J.&J.’s one-shot vaccine more than ever. But the company is behind on manufacturing promises made in its Operation Warp Speed contract.

Johnson & Johnson expects to release critical results from its Covid-19 vaccine trial in as little as two weeks — a potential boon in the effort to protect Americans from the coronavirus — but most likely won’t be able to provide as many doses this spring as it promised the federal government because of unanticipated manufacturing delays.

If the vaccine can strongly protect people against Covid-19, as some outside scientists expect, it would offer big advantages over the two vaccines authorized in the United States. Unlike those products, which require two doses, Johnson & Johnson’s could need just one, greatly simplifying logistics for local health departments and clinics struggling to get shots in arms. What’s more, its vaccine can stay stable in a refrigerator for months, whereas the others have to be frozen.

But the encouraging prospect of a third effective vaccine is tempered by apparent lags in the company’s production. In the company’s $1 billion contract signed with the federal government in August, Johnson & Johnson pledged to have 12 million doses of its vaccine ready by the end of February, ramping up to a total of 100 million doses by the end of June.
