Ontario’s chief medical officer of health, worried about the impact the Delta Variant will have on COVID caseloads this fall, thinks the province should revise its vaccination criteria for moving to the next step of the reopening.
Dr. Kieran Moore thinks 90 per cent of eligible Ontario residents should be fully vaccinated first, instead of 75 per cent, with 80 per cent partially vaccinated. Just 62 per cent of Ontarians have had two doses.
Dr. Moore says it will be hard to build community immunity with 20 per cent of the population unvaccinated.
“Certainly I’d love Ontario to have one of the highest vaccination rates in the world. The modelling, though, tells us that once we’re at around 90 per cent of the eligible population immunized that the risk of Delta will be less for us,” Moore said during a briefing on Tuesday. “If we remain at around 20 per cent of the population unvaccinated we won’t build a community immunity and you’ll get breakthrough infections in those individuals that are vaccinated because not all individuals, especially those that are elderly or vulnerable or immune-suppressed, will get full protection from the vaccine. So the higher the proportion of our population immunized the less we’ll have to worry about those vulnerable people getting COVID despite getting vaccinated.”
The province administered more than 132,000 doses of COVID-19 vaccine on Monday, but only about 17,000 of those were first doses. At that rate, it could take months for Ontario to hit the 90 per cent threshold among eligible residents.
