The Ontario government has moved up second doses for those who got a COVID-19 shot in May while three more local public health units were added as hot spot areas where the Delta variant is of concern.
In new documents released Thursday, officials said Ontarians who got a first dose from May 10 to May 30, and are in a Delta hot spot, can book an earlier second shot starting Wednesday, June 23.
The rest of Ontarians, not in a Delta hot spot and who got a first dose from May 10 to May 30, will be eligible for a “gradual acceleration” for a second shot starting on Monday, June 28.
Last week, Ontario announced that those in Delta hotpots were eligible to get an earlier second vaccine dose if they received a first shot on or before May 9.
Three more local public health units — Hamilton, Simcoe-Muskoka and Durham Region — were added as Delta hot spots, joining Toronto, Halton, Peel, Porcupine, Waterloo, Wellington-Dufferin-Guelph and York.
As of June 17, 75 per cent of adult Ontarians have received at least one dose with more than 19 per cent of adults who are fully vaccinated with two shots.
Ontario has administered 11.9 million doses with more than 2.3 million people immunized with two shots. An average of 185,300 doses are being administered daily.
The province is expected to receive a few million more doses between Pfizer and Moderna by the end of June.
When it comes to what people will receive as a second dose, officials said residents will likely learn which vaccine they will receive at the time of their appointment due to supply versus at the time of booking or what their first shot was.
For those who got a first dose of AstraZeneca, eligibility to get another AstraZeneca shot or Pfizer or Moderna was reduced to as early as eight weeks to 12 weeks.
“In general, longer intervals between vaccine doses result in stronger final immune response. The circulation of the B.1.617.2 (Delta) variant of concern in some areas of Ontario, however, warrants consideration of a shorter interval,” the documents indicated.
When it comes to Ontario’s youth aged 12 to 17, more than 48 per cent have gotten at least one dose with second doses scheduled between Aug. 9 and 22. For seniors aged 70 and older, there is over 90 per cent first dose coverage with 39 to 59 per cent for second doses.
