If unadjuvanted vaccine is safe and equally effective, and it takes less time to produce, why did you recommend Canadians wait for adjuvanted vaccine only to give them unadjuvanted now?
The World Health Organization recommended countries use dose-sparing vaccines whenever possible. By developing an adjuvanted vaccine, we were able to use less of the virus material (antigen), allowing us to produce more vaccine with an aim to immunize more people in a timely manner. The Government of Canada has ordered enough adjuvanted vaccine to vaccinate all Canadians who need and want it, and remains the recommended formulation for most people.
