How viral vector and mRNA COVID-19 vaccines work

Global News published this video item, entitled “How viral vector and mRNA COVID-19 vaccines work” – below is their description.

From viral vector vaccines like AstraZeneca to mRNA vaccines like Pfizer and Moderna, they all have the same goal: to train your body how to fight off COVID-19. But, they use different strategies to create antibodies.

For example, AstraZeneca uses a crippled virus to deliver the coronavirus spike protein, while Pfizer and Moderna use mRNA, the part of the coronavirus’ genetic code and teaches your cells how to make a protein that will trigger an immune response.

Global’s Gloria Henriquez explains how the different COVID-19 vaccines available in Canada work.
