CALGARY – Alberta’s top doctor confirms that 10 people linked to delta variant outbreaks of COVID-19 at Calgary’s Foothill Medical Center have been fully immunized before testing positive for the disease.

“What we are monitoring now is whether or not they have had a milder course of the disease or not, as you might expect,” said Dr. Deena Hinshaw, Chief Medical Officer of Health for Alberta. , during the provincial COVID-19 briefing on Thursday.

According to Alberta Health Services, a dose of an mRNA vaccine – like Pfizer and Moderna – offers 73 percent protection against the alpha variant. This immunity increases to 91% with a second dose.

For the delta strain, a first dose offers 33% protection and a second dose 88%.

“While we may see a few cases that have successfully passed the vaccine, the vast majority of people vaccinated will be protected,” Hinshaw said.

The AHS on Wednesday confirmed 16 cases of variant B.1.617.2 in patients at two units at Foothills Medical Center. Six healthcare workers have also tested positive for the variant.

The hospital has seen several outbreaks during the pandemic, but this is the first involving the delta variant.

The hospital remains open and has the capacity to treat all patients, although AHS has said the two units affected by the outbreaks are not accepting admissions. Transfers of patients to long-term care centers from the two units with the delta variant are also suspended.
