Impact of Johnson & Johnson Vaccine Pause on Public Health Efforts

Federal health agencies on Tuesday called for a pause in the use of Johnson & Johnson’s coronavirus shot as they examine a rare blood-clotting disorder that emerged in six recipients.

Every state, the District of Columbia and Puerto Rico halted their rollout of the Johnson & Johnson vaccine almost immediately. The same went for the U.S. military, federally run vaccination sites, and CVS, Walgreens, and other stores.

Today, science writer Carl Zimmer explains the decision-making process, how long the suspension might last and the impact it could have not only in the U.S. but around the world.

Guest: Carl Zimmer, a science writer and author of the “Matter” column for The New York Times.
