President Joe Biden will announce Tuesday that pharmaceutical giant Merck will help make Johnson & Johnson’s Covid-19 vaccine, a senior administration official confirmed to NBC News.
The announcement comes as the administration works to ramp up the production of J&J’s single-shot vaccine. Senior administration officials said Sunday the U.S. government would ship J&J’s entire inventory of 3.9 million doses this week, adding that supply would be “uneven” in the following weeks. Sixteen million more doses are expected by the end of the month.
