With the largest vaccination campaign underway, the province has administered more than 32.0 million doses into the arms of Ontarians. According to data last updated on April 4, numbers released by the Ministry of Health show health officials administered 4,052 vaccine doses on Sunday, down from 9,003 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 the critical threshold for vaccination is now estimated to be at least 90% of the population. That translates to roughly 13,050,000 people that would need to be vaccinated to achieve herd immunity against Covid-19.

So far, 12,609,322 people have received at least one or both shots of the vaccine, 87.0% of the entire population (green segment).

A total of 12,125,870 people are fully inoculated against the virus. That number represents about 83.6% of the Ontario population, (yellow segment).
