The Saskatchewan government has shot a boost of optimism into its fight against COVID-19, announcing it will join other provinces by delaying the second dose of vaccines to speed up immunizations.

Speaking Thursday at a news conference with other premiers, Premier Scott Moe said people will get their second shot up to four months after the first, which falls in line with a recent recommendation from Canada’s national immunization committee.

Alberta, Manitoba and other provinces made similar announcements after British Columbia first said Monday it was moving to a four-month delay.

The shift comes as health experts point to people being well protected against the novel coronavirus with a first dose, noting the country faces a limited supply of vaccines.

“The benefits are tremendous,” Dr. Saqib Shahab, Saskatchewan’s chief medical health officer, said during a briefing.

Moderna, Pfizer, AstraZeneca or Johnson & Johnson: Which COVID-19 vaccine will I get in Canada?

Canada pre-purchased millions of doses of seven different vaccine types, and Health Canada has approved four so far for the various provincial and territorial rollouts. All the drugs are fully effective in preventing serious illness and death, though some may do more than others to stop any symptomatic illness at all (which is where the efficacy rates cited below come in).


  • Also known as: Comirnaty
  • Approved on: Dec. 9, 2020
  • Efficacy rate: 95 per cent with both doses in patients 16 and older, and 100 per cent in 12- to 15-year-olds
  • Traits: Must be stored at -70 C, requiring specialized ultracold freezers. It is a new type of mRNA-based vaccine that gives the body a sample of the virus’s DNA to teach immune systems how to fight it. Health Canada has authorized it for use in people as young as 12.


  • Also known as: SpikeVax
  • Approved on: Dec. 23, 2020
  • Efficacy rate: 94 per cent with both doses in patients 18 and older, and 100 per cent in 12- to 17-year-olds
  • Traits: Like Pfizer’s vaccine, this one is mRNA-based, but it can be stored at -20 C. It’s approved for use in Canada for ages 12 and up.


  • Also known as: Vaxzevria
  • Approved on: Feb. 26, 2021
  • Efficacy rate: 62 per cent two weeks after the second dose
  • Traits: This comes in two versions approved for Canadian use, the kind made in Europe and the same drug made by a different process in India (where it is called Covishield). The National Advisory Committee on Immunization’s latest guidance is that its okay for people 30 and older to get it if they can’t or don’t want to wait for an mRNA vaccine, but to guard against the risk of a rare blood-clotting disorder, all provinces have stopped giving first doses of AstraZeneca.


  • Also known as: Janssen
  • Approved on: March 5, 2021
  • Efficacy rate: 66 per cent two weeks after the single dose
  • Traits: Unlike the other vaccines, this one comes in a single injection. NACI says it should be offered to Canadians 30 and older, but Health Canada paused distribution of the drug for now as it investigates inspection concerns at a Maryland facility where the active ingredient was made.

How many vaccine doses do I get?

All vaccines except Johnson & Johnson’s require two doses, though even for double-dose drugs, research suggests the first shots may give fairly strong protection. This has led health agencies to focus on getting first shots to as many people as possible, then delaying boosters by up to four months.

“We can emerge out of the pandemic three months earlier than we had anticipated. With a two-dose program, it would have taken us till September. Now we can vaccinate everyone 18 and older as early as June.”

Provincial health officials said that starting Friday, staff will only be giving first shots. The change will not apply to people who have appointments booked to receive a second dose, long-term care residents and staff, as well as those in personal care homes.

Shahab said since vaccinations started in long-term care homes, there have been fewer outbreaks and infections in the facilities.

To date, about 84,000 vaccinations have been done in Saskatchewan out of the roughly 400,000 shots needed to inoculate residents 70 and older and health-care workers at risk of COVID-19 exposure.

Scott Livingstone, CEO of the Saskatchewan Health Authority, said he expects most of these vaccinations under the first stage of the province’s immunization program will be finished in early April.

He also asked for patience, as the authority has to adjust how it delivers vaccines with the new four-month window between doses.

Saskatchewan reported 169 new COVID-19 cases and two more deaths on Thursday. The province of 1.1 million people also continues to lead the country with the highest rate of active cases per capita in Canada.

Moe said earlier in the week that delaying the second dose of vaccine would be a game-changer for how long public-health restrictions need to stay in place.

The current order is in effect until March 19. Shahab said decisions about what rules might be relaxed could come next week.

“I know it’s been very hard for people not to be able meet each other in their houses,” he said.

“In the past, we did have, you know, two to three households as a bubble of up to ten. So that’s something that we’re looking at.”

The Ministry of Health also said it would use 15,000 doses of the Oxford-AstraZeneca vaccine on people aged 60 to 64 and certain health-care workers. A national panel has recommended it not be used on seniors.

The province said these vaccinations will start later this month and eligible residents will be able to book an appointment by phone through a system that is expected to launch next week.

Premiers say federal COVID-19 vaccine procurement delays have left them no choice but to stretch out the time between doses. British Columbia announced Monday it would allow up to four months between doses. Several other provinces followed suit after a national panel of vaccine experts recommended such an extension would be appropriate if supplies are limited.
