After US FDA authorization for additional COVID vaccine shots, the focus now shifts to CDC’s advisory committee, which may be concerned about variations in eligible populations, timing and dosing when it comes to giving a booster different from the primary vaccination series.

The European Medicines Agency has OKd new manufacturing sites and a ready-to-use formulation for Comirnaty, while Australia has provisionally approved Ronapreve for treatment and post-exposure prophylaxis. The UK has secured supplies of two investigational antiviral products from Pfizer and MSD.

The company is currently providing its COVID-19 vaccine on a not-for-profit basis but expects that will change as the pandemic phase of the crisis abates.
