Vaccines can lose their effectiveness when exposed to light or temperatures outside +2°C and +8°C range. Toronto Public Health inspects all facilities storing publicly funded vaccines to ensure vaccines retain their potency and reduces vaccine wastage. Learn more about vaccine storage and handling guidelines.
Contact Toronto Public Health whenever vaccine fridge temperature is out-of-range (<2°C or > 8°C).
