Health Canada releases details on the new Moderna Spikevax COVID-19 bivalent vaccine.
September 7, 2022 | News, COVID-19
After a thorough and independent scientific review of the evidence, Health Canada has determined that the bivalent Moderna Spikevax booster is safe and effective. Clinical trial results showed that a booster dose of the bivalent Moderna Spikevax vaccine triggers a strong immune response against both Omicron (BA.1) and the original SARS-CoV-2 virus strain. It was also found to generate a good immune response against the Omicron BA.4 and BA.5 subvariants, and is expected to extend the durability of protection. Further information can be found here.
The National Advisory Committee on Immunization has released the following recommendation for use of the new bivalent vaccine:
- Individuals under 12 years of age who are at increased risk of severe illness from COVID-19 should be offered a fall COVID-19 vaccine booster dose regardless of the number of booster doses previously received.
- All other individuals 12 to 64 years of age may be offered a fall COVID-19 booster dose regardless of the number of booster doses previously received.
- Authorized dose of a bivalent Omicron-containing mRNA COVID-19 vaccine should be offered as a booster dose to the authorized age groups (under 18 years of age). If the bivalent Omicron-containing mRNA COVID-19 vaccine is not readily available, an original mRNA COVID-19 vaccine should be offered to ensure timely protection.
- Authorized dose of a bivalent Omicron-containing mRNA COVID-19 vaccine may be offered to adolescents 12 to 17 years of age with moderately to severely immunocompromising conditions and/or who have biological or social risk factors that place them at high risk of severe outcomes from COVID-19.
