J&J shot shipments to be low until FDA OKs plant

J&J is working closely with regulators to resolve the issues holding up authorization, said Jeff Zients, the White House's COVID-19 response coordinator. It expects to start shipping 8 million doses per week towards the end of April and remains on track to deliver around 100 million shots by the end of May, he added.

The United States remains on track to give out 200 million doses by President Joe Biden's 100th day in office, Zients said. It has so far dosed 112 million people and fully vaccinated 66 million people, he said.
