Despite increased media attention to the possibility that the novel coronavirus may have escaped from a lab, no credible evidence has emerged to support it and most scientists think the virus likely has a natural origin.
We look at what is known about the rare clotting conditions associated with the Johnson & Johnson vaccine, their frequency and the risks of COVID-19.
Nearly 200 million doses of COVID-19 vaccines have been administered in the U.S., including 7.2 million doses of the Johnson & Johnson vaccine. The CDC and FDA recommended “a pause in the use” of the J&J vaccine “out of an abundance of caution” because of six cases of a rare type of blood clot.
Since the Centers for Disease Control and Prevention began recommending that members of the public mask up last spring, additional research has backed the use of face masks to combat the coronavirus, but knowledge gaps still remain. Here, we summarize the evidence.
The Johnson & Johnson vaccine is the third COVID-19 vaccine to be authorized by the Food and Drug Administration. Here, we give a rundown of basic facts about the vaccine and an overview of how it works.
Moderna’s mRNA vaccine is the second COVID-19 vaccine to be authorized and fully approved for use in the U.S. Here, we give a rundown of basic facts about the vaccine and an overview of how it works.
Three COVID-19 vaccines are now authorized in the U.S. In this story, we answer some common questions about the shots.
A primer on the first COVID-19 vaccine to receive authorization and approval in the U.S.
We’ll run through how the tests work and why it’s so hard to interpret what the results might mean.
Federal officials have provided confusing and sometimes contradictory statements about the number and availability of tests to diagnose new coronavirus infections. We’ll explain how testing works, what happened with the CDC’s coronavirus test and what’s known about how many tests are available in the U.S.
