Hospitalization and death rare with 3 vaccine doses: Report

New Toronto Public Health (TPH) data show that individuals with three doses of COVID-19 vaccine had the lowest hospitalization, intensive care unit admissions, and deaths over any other level of vaccination throughout the Omicron wave. 

Furthermore, the risk of hospitalization increases with age and the more under-vaccinated an individual is.

The data also demonstrated that vaccination has been effective in Toronto’s COVID-19 response throughout the Omicron wave, with breakthrough infections happening in only 2.4 per cent of individuals in Toronto with at least two doses of COVID-19 vaccine, and at least 14 days have passed from the date of administration of the second dose. This represents 56,659 cases among more than 2.3 million Toronto residents five years of age and older who had at least two doses of vaccine between December 21 and January 24.

In addition, there is even greater protection provided with three doses of COVID-19 vaccine. Those with three doses had the lowest hospitalization, ICU, and death over any other level of vaccination. 

The older and more under-vaccinated a case, the more likely they are to require hospitalization. Unvaccinated individuals 60 years of age or older are at a risk at least six-times higher of hospitalization from COVID-19 infection compared to those with three doses. They also have 14-times higher risk of ICU admission from COVID-19 illness, compared to those with three doses. 

The benefit of three doses is also evident when comparing those 60 years of age and older with two doses to those with three doses. The risk of hospitalization is four times higher with only two doses while the risk of ICU admission is seven times higher, according to a report from TPH.
