The short answer is yes, but the real question is how severe the resurgence of COVID-19 cases will be. According to Canada’s latest modelling, the fourth wave is set to be driven by the delta variant; its impact on the general public, however, will directly correlate with the number of people who are fully vaccinated (Aiello, 2021).
The pandemic of the unvaccinated
The Ontario Hospital Association (OHA) has also warned that the upcoming surge in COVID case numbers could become a great threat to the province (Johnson, 2021). Ontarians who have yet to receive two doses are now considered to be the most vulnerable population. Officials are calling this upcoming fourth wave “the pandemic of the unvaccinated” (Johnson, 2021).
“The updated longer-range forecast shows how the epidemic trajectory may evolve through early September. It suggests that we are at the start of the Delta-driven fourth wave, but that the trajectory will depend on ongoing increases in fully vaccinated coverage, and the timing, pace and extent of reopening,” – Dr. Theresa Tam, Chief Public Health Officer of Canada
A Disproportionate Impact
In a recent interview, Federal Indigenous Services Minister Marc Miller expresses his concern as he fears that this Delta-driven fourth wave would heavily impact marginalized communities, especially Indigenous peoples (Malone, 2021). According to Miller, a large portion of Indigenous peoples, particularly those living on reserves, are children under the age of 12, who are not eligible to get a dose (Malone, 2021). The biggest threat to unvaccinated individuals however, is the rising number of delta variant cases.
Outbreaks of the Delta variant have already begun to pop up on reserves within the past few weeks. In northern Saskatchewan, the Black Lake First Nation went into lockdown last month as the Delta variant spread rapidly and affected around 1600 individuals (Malone, 2021).The Athabasca Health Authority also claims that the number of cases this week reached over 200—ultimately requiring those living in affected areas to self-isolate (Malone, 2021).
Taking a closer look at the numbers
Hospitalization rates across the region have continued to remain low, with less than 1% of hospitalized cases occurring in people who are fully vaccinated (Aiello, 2021). That being said, 89.7% of all hospitalized cases occurring in unvaccinated people are those who are eligible to receive the vaccine (Aiello, 2021).
Out of the 84.9 % hospitalized cases who are unvaccinated, 5.3%of cases are those who are not yet eligible for vaccines, and 4.6% are those who are partially vaccinated. (Aiello, 2021)
“I think it’s going to be primarily be younger unvaccinated children [affected], and of course the adults who have chosen not to get the vaccine,” – Dr. Steve Flindall, York Region Emergency Physician
