Pioneering COVID-19 cases lead to only 9 ontarians under 60 in the intensive care unit

TORONTO – There have been more than 17,000 so-called breakthrough cases of COVID-19 involving fully vaccinated Ontarians over the past year, but the number of people under 60 who eventually ended up in an intensive care unit is only nine.

Public Health Ontario has prepared a new report examining the incidence of breakthrough infections in the province until November 14th.

The report provides the most comprehensive look at breakthrough infections in Ontario to date and seems to support the testimony of public health experts who have consistently claimed that the vaccines are extremely effective in preventing both symptomatic infection and hospitalizations.

The data show that there have been 17,596 breakthrough cases among the more than 11 million Ontarians who are fully vaccinated, accounting for 3.8 percent of all laboratory-confirmed cases.

But it also suggests that the proportion of fully vaccinated people who end up in hospital is even lower, especially among those under 60 years of age.

In fact, over the past year, only 83 people under the age of 60 have ended up in hospital with a breakthrough case of COVID-19. Of these individuals, only nine of them have required treatment in an intensive care unit.

In comparison, a total of 8,355 unvaccinated people under the age of 60 ended up in hospital with COVID-19 during the same period, and 1,722 of them required treatment in the intensive care unit.

Across all age groups, the number of people with breakthrough infections who ended up in intensive care is 81, accounting for about 1.9 percent of the COVID-19 intensive care unit.

The release of the data comes as fully vaccinated individuals begin to account for an increasing share of Ontario’s total case load, and sometimes they even account for the majority of new infections in the province’s daily number of cases.

But the authors of the report warn that an increasing proportion of breakthrough infections can be expected, with more than 85 percent of Ontarians aged 12 and up now fully vaccinated.

They say the evidence continues to suggest that when COVID-19 cases occur after vaccination, “there is evidence that vaccines reduce symptomatic infection, the severity of the disease, as well as transmission.”

“Over time, as a population becomes more highly vaccinated, the number of post-vaccination cases, including breakthrough cases, is likely to increase,” the report notes. “Even with a very effective vaccine, cases may occur among vaccinated individuals because a larger proportion of the population is vaccinated than unvaccinated.”

Data released by Public Health Ontario suggests that the number of COVID-19 infections in fully vaccinated individuals has “remained consistent over time,” even with many of these people now months away from receiving their second dose, and Ontario begin administering booster shots to a small group of individuals due to concerns about declining immunity.

However, infectious disease specialist Dr. Isaac Bogoch to CP24 Thursday morning that it also points to the need for a broader rollout of third doses.

So far, there have been only 40 cases of breakthrough cases of COVID-19 involving individuals who are 14 days out of a third dose.

“If we look at the data, it’s pretty clear that we could or should not expand the eligibility to third doses,” he said. “We do not all need third doses and we can discuss which age group would be best served with third doses at the moment, but I take care of 50 and up. Other people might look at the data and say something else. is ok. But I think it’s fair to say we should expand third doses in Ontario. “
