Why get vaccinated
Safe and reliable vaccines can help protect you and your family from COVID-19covid 19. They will be an important tool to help stop the spread of the virus and allow individuals, families and workers to safely resume normal life.When a large percentage of the population becomes immune to COVID-19covid 19, the spread of the virus will slow down or stop.
Vaccine protection is different for each disease. For example, to stop their spread:
- approximately 80% of the population must be immune to polio
- up to 95% of the population must be immune to measles
Building immunity takes time
Both the Pfizer-BioNTech and Moderna vaccines approved for use in Canada require two doses, administered a 21 to 28 days apart, for your body to develop infection fighting response.Health officials anticipate that these vaccines will be effective against the original strain of COVID-19covid 19 and the new variant identified in the UK.
Until vaccines are widely available for everyone to receive two doses and enough people are vaccinated to stop the spread, we all must:
- continue to follow local public health advice and restrictions
- take the necessary health precautions, like practising physical distancing, washing hands and using masks or face coverings
- stay home – only go out for necessities
