mRNA vaccines are so new, how do we know they are not experimental?

Vaccines are rigorously tested and reviewed by Health Canada before they are approved for use. mRNA vaccines have been studied for years and could be developed faster because they were made in lab using materials that are easily available. Most adverse reactions to vaccines emerge within 6 weeks of immunization which is why vaccine manufacturers are required to produce 8 weeks of safety data. The Yukon places high priority on vaccine safety therefore continues to closely monitor any vaccine side effects.
