Merck & Co. will help make rival Johnson & Johnson’s Covid-19 vaccine in order to boost the slower-than-promised production of the one-dose shot, U.S. President Joe Biden said on March 2.

The Biden administration is exploring every option for increasing manufacturing of Johnson & Johnson’s Covid-19 vaccine, which is under regulatory review, and said on Feb. 5 that currently expected levels of early doses were less than hoped.

Hours after being sworn in as the 46th President of the United States, Joe Biden signed 10 executive orders aimed at combating the ongoing Covid-19 crisis.
