the province says the shortened interval could be as small as 28 days for the pfizer-biontech and moderna vaccines in the coming months, depending on supply.
those who got a first shot of the oxford-astrazeneca vaccine will be offered a second dose after 12 weeks, though it could be a different vaccine depending on awaited federal guidance.
moving up the second dose is optional and people will keep their original appointments if they don’t re-book for an earlier shot.
ontarians aged 80 and older can start booking their second doses next week, and the provincial booking system has been modified to allow those who were vaccinated before the system came online to book their second shot. until now, that group had been frozen out because the system didn’t recognize that they had already received one vaccination.
those aged 70 and older will become eligible for second shots in the week of june 14.
after that, the province says residents will become eligible for second shots based on when they got their first dose.
those between the ages of 12 and 25 will become eligible in early august.
