A US Centers for Disease Prevention (CDC) advisory panel is scheduled to meet on Friday 23 April to decide whether to continue the pause of J&J’s Covid-19 vaccine rollout. The panel will examine additional cases that have come up and assess risks arising from its administration.

Eli Lilly has requested that the US Food and Drug Administration (FDA) revoke the emergency use authorisation (EUA) for bamlanivimab (LY-CoV555) 700mg as a Covid-19 monotherapy. The request comes as Lilly transitions to only supplying bamlanivimab and etesevimab in combination to treat Covid-19 in the country. Lilly’s request was in view of the surge in Covid-19 variants across the US and not related to any safety concerns.
