The head of the vaccine programme for Canada's most populous province expects to get every adult in Ontario a first vaccine shot by June 20, AP reported.
Ontario and provincial governments in the country are extending the interval between the two doses of Pfizer, Moderna and AstraZeneca vaccines to four months rather than three to four weeks so they can quickly inoculate more people.
Retired Gen Randy Hillier says by the first day of summer he wants everyone in Ontario who is eligible to get a dose. Hillier says the first dose offers an incredible level of protection.
