With the largest vaccination campaign underway, the province has administered more than 3.8 million doses into the arms of Ontarians. On April 18, the Ministry of Health reported 86,565 doses administered, down from 107,278 doses the day prior.

This graph represents Ontario’s progress thus far in the vaccination campaign (see above). The dark blue bar represents the population of Ontario, an estimated 14.5 million. Health officials suggest roughly 80% of the population would need to be vaccinated to achieve herd immunity against Covid-19.

So far, 3,492,571 people have received at least one or both shots of the vaccine, 24.1% of the entire population (green segment).

A total of 345,310 people are fully inoculated against the virus. That number represents about 2.4% of the Ontario population, (yellow segment).
