Coronavirus Update: J&J Vaccine On Pause Amid Reports Of Clots
Plus: Variants And Efficacy, Veklury Study Halted
The CDC and FDA recommended a pause on dosing of J&J's one-shot vaccine. Pfizer/BioNTech's vaccine showed signs of lower efficacy against the B.1.351 variant, but a prominent expert called the data "misleading." Gilead halted its Phase III study of Veklury in non-hospitalized, high-risk patients. And Rigel's Tavalisse may have a shot in the sickest COVID-19 patients despite the small size of a Phase II study.
