We should vaccinate 6 million people with first dose NOW. It is deadly cautious to hold second dose in *reserve*. Supply chain will be ok and the exact timing of the second dose is not magical and likely not critical.

Modelling by a group at the University of Toronto confirmed.

Ashleigh Tuite, an epidemiologist at U of T’s Dalla Lana School of Public Health….said she and her colleagues projected that frontloading vaccine doses would avert between 34 and 42 per cent more symptomatic coronavirus infections, compared with a strategy of keeping half the shipments in reserve.

“It makes much more sense to just get as many people their first doses as soon as possible,” Dr. Tuite said.

…everyone should get the second dose on schedule, but if supply issues delay that injection by a week or two, it shouldn’t hamper how well the vaccines work.

According to Abigail Bimman at Global News, Ontario will now switch to getting as many first doses out as possible:

NEW: Ontario is changing its vaccine policy and no longer reserving second doses, but getting all of the initial 90k out the door- they expect to finish them in the “next several days” – Health Minister’s office tell @globalnew. Change due to confidence in supply chain.

It’s not all the way to first doses first but it’s a minimally risky, smart move. Indeed, Nova Scotia, Saskatchewan and British Columbia already have said that they won’t hold back first doses.

The United States should listen to the wise Canadians.
