At-risk Manitobans likely to be prioritized for 1st doses of AstraZeneca COVID-19 vaccine this month

Some Manitobansmost at-risk of getting gravely ill or dying from COVID-19 could be at the top of the list to receive the newly approvedAstraZeneca-Oxford vaccine when it arrives in the province in the coming weeks.

Manitoba vaccine task force leader Dr. Joss Reimer said WednesdayManitoba will receive its first shipment inmid-March, though it's unclear how many doses will be in that batch.The first doses arrived in Canada on Wednesday.

The province is still working out who will get the first doses, but Reimer said the first phase will likely target peopleage50 to 64. Within that group, officials are trying to identify who is most at-risk, Reimer said.

"We don't have the final list of who will be the top priority groups, but we are specifically looking through the epidemiology," she said at a Wednesday news conference.

Health Canada approved thevaccine late last week for all age groups. Butthe National Advisory Committee on Immunizations, or NACI, advised against giving AstraZeneca-Oxford to people older than 65, citing a lack of clinical data.

The benefit of the vaccine compared to the Pfizer-BioNTech and Moderna versions is thatAstraZeneca-Oxford doesn't have the same extreme-coldstorage requirements.That makes it ideal for distribution in doctors' offices and pharmacies as opposed to immunization super sites with the specialrefrigeration systems.

The arrival of AstraZeneca-Oxford's vaccine alsorevises immunization timelines across Canada potentially cutting projections in Manitoba down by two to three months.

Reimer didn't provide a revised timeline for Manitoba on Wednesday,but last week she said the province'shigh-supply vaccination scenario is now likely givenAstraZeneca-Oxford's approval.

That timeline aims to have all eligible Manitobans fully immunized by the end of August.A low-supply scenario, based on the presence of only the Moderna and Pfizer-BioNTech vaccines, pegged the end date for November.

1st possible group to getAstraZeneca

Reimer said officials are still in the planning phase for distribution of AstraZeneca, but said people determined to be at risk in the 50 to 64 age range are likely to prioritized.

For example, she said, epidemiological data showspeople on dialysis for kidney failure and those with cirrhosis of the liver have been disproportionately impacted by COVID-19. People in those groups over the age of 50 and under 64 could be among the first to receiveAstraZenecadoses later this month, among other at-risk groups, said Reimer.

So far more than 80,000 vaccine doses overall have been doled out in Manitoba about 50,000 first doses and 30,000 second doses, said Reimer.

The goal is to hit 20,000 per day from April to June, which would amount to 1.5 million vaccinations in those three months.

The latest estimates suggest2,277 injections could be done per day in March, though that could change depending on supply.

The federal government recently informed provinces to expectModerna and Pfizer-BioNTechvaccine shipments between April and Juneon a per capita basis, with no additional allotment for province's with proportionally higher Indigenous populations, Manitoba Health Minister Heather Stefansonsaid on Wednesday.

That represents a departure from shipments received in thefirst months of 2021, when Manitoba received more vaccinesdue to its high proportion ofIndigenous people.

Vaccination timelines could also change now that Manitoba is planning to extend the amount of time between first and second doses.

Reimer announced that shift Wednesday, following in B.C.'s footsteps, saying the latest real-world evidence suggests people with one doses receive a considerably higher degree of protection than what the clinical trials originally showed.
