The big vaccine pivot: Merck falters on Covid-19 shots, then makes one for rival

Live Mint  

Weeks after Merck & Co. scrapped development of its Covid-19 vaccines in January, one of its senior manufacturing officials began phoning his deputies, telling them their work on a pandemic shot wasn’t actually over. J&J’s unusual collaboration with a rival, and Merck’s speedy manufacturing run-up, reflect one of the biggest challenges of the pandemic: making enough Covid-19 vaccines to meet the high demand. Last December, at the urging of the federal government, the rivals began discussing whether Merck could help make J&J’s Covid-19 vaccine. During a Jan. 4 call between U.S. officials, Dr. Stoffels and then-Merck Chief Executive Ken Frazier, the companies agreed to assess whether Merck’s plants could adapt to make J&J’s shot, the people said. Despite the available rooms and equipment, Merck needed to upgrade its facilities, because J&J’s vaccine uses vials smaller than Merck’s failed Covid-19 shots, as well as a newer vaccine technology.
