The new bivalent booster, which targets the original virus and the Omicron BA.1 strain, was approved by Health Canada on Sept. 1. Those who opted to get their fourth dose after this summer's announcement have a long wait ahead. Story continues"They should be reassured they do have some protection ... they'll just have to delay their [bivalent] booster dose until potentially the new year or later in the fall season." Saxinger said work will be done in the months ahead to analyze the optimal timing for the bivalent shot after a fourth dose of the original vaccine. Meanwhile, Smith hopes the release of the new bivalent vaccine will prove more appealing to Albertans who have, so far, resisted a booster dose.
