Do the COVID vaccines really work?

Yes, all approved vaccines are very effective. That’s why doctors are recommending them to nearly all Manitobans.  

The vaccines approved for use in Canada are highly effective at preventing severe disease, hospitalization and death. They have similar protection compared to existing routine vaccines for other diseases like polio and measles, and much better effectiveness than the flu shot.  

The safety and efficacy of approved COVID-19 vaccines has been demonstrated both in clinical trials and in the real world. Over 5 billion doses have been safely administered in dozens of countries and new reviews of real-world data are finding the vaccines offer very strong protection against COVID-19. Further research is also finding the vaccines can decrease the spread of COVID-19.
