On Jun. 2, 2022, Moderna announced an agreement with the European Commission (EC) to amend their originally agreed contractual delivery schedules for the Moderna COVID-19 vaccine booster product (Spikevax, mRNA-1273) or updated booster vaccine candidate.

The amendment allows participating Member States to have Moderna COVID-19 vaccine booster doses scheduled for delivery in the second quarter of 2022 to be delivered later in calendar year 2022 or early calendar year 2023. Participating Member States will have the possibility to receive the expected updated bivalent booster candidate following approval by the European Medicines Agency.
