I’ve had one dose of the COVID-19 vaccine. How protected am I? 

Building community immunity takes time. Even after getting your first dose of the COVID-19 vaccine, continue to stay vigilant and follow public health advice.

According to Public Health Ontario, the first dose of a COVID-19 vaccine is 60-80% effective in protecting against COVID-19 at 21-28 days after vaccination. The protective effects of the first dose of the vaccines take weeks to develop. Effectiveness of the first dose is not immediate. Receiving one dose is not the same as being fully vaccinated. 

Relaxing public health measures for partially-vaccinated individuals is not recommended.

I have had my second dose- Can I go back to my regular activities, without public health measures?

The simple answer is no, at least not right away.

It takes about two weeks for your immune system to develop protection. Continued public health measures like wearing your mask or face covering, practising physical distancing, and washing your hands frequently is necessary. This is recommended for everyone, including individuals who are fully vaccinated. Until we achieve widespread protection against the virus, we have to continue to protect those around us who have yet to be vaccinated or had their second dose.  

As the Ontario vaccination program continues, expect updated guidance to be coming soon.
