The anticipated COVID-19 bivalent booster shot that specifically targets the Omicron variant is now available across Canada.
But provinces and territories have different eligibility criteria and recommendations on how long people who’ve received previous vaccine doses should wait until they receive the bivalent vaccine.
The bivalent vaccine is able to specifically target Omicron, which is currently the predominant variant circulating globally, as the formula contains a mixture of spike protein elements from both the original COVID-19 virus and the Omicron variant.
Health Canada has approved bivalent vaccines manufactured by both Moderna and Pfizer-BioNTech. Moderna's combination vaccine targets the original strain of the COVID-19 virus and the first Omicron variant, while Pfizer's vaccine targets the BA.4 and BA.5 strains.
While the bivalent booster has been designed to target the BA.1 strain of Omicron, it should provide strong protection against the more prevalent strains, BA.4 and BA.5, Dr. Vinita Dubey, Toronto’s Medical Officer of Health, told CTV Toronto earlier this month.
Most jurisdictions are following the advice of the , which is that the bivalent booster be provided to those 18 and older and following a six-month period after the last dose.
