Health Canada authorized SPIKEVAX Bivalent (elasomeran/imelasomeran) on September 01, 2022 . In order to provide rapid access to SPIKEVAX Bivalent , Moderna will distribute product vials and cartons labelled in English only with the brand name “ SPIKEVAX 0 (Zero) / O (Omicron)” for a period of time . As a result, important Canadian-specific information is absent from these labels (see the Information for healthcare professionals section). The bivalent SPIKEVAX TM 0 (Zero) / O (Omicron), 0.10 mg/mL, 2.5 mL shares the same coloured vial cap (royal blue) to monovalent SPIKEVAX 0.10 mg/mL , 2.5 mL. To avoid medication errors, pay careful attention to the vial and carton label .
