That change in the air isn't just the coming of spring: there's a shift happening in the political dynamic surrounding COVID-19 vaccinations. After weeks of the federal Liberal government taking heat for the slow arrival of vaccines in Canada, it's provincial premiers who must now answer to jittery, impatient voters hoping to be immunized as soon as possible. New Brunswick's Liberal opposition is now pushing Premier Blaine Higgs and his Progressive Conservative government for more details about the provincial vaccination plan — details they say other provinces have been providing to their citizens. "We're not trying to play politics with this, but there's certainly not a lot of information being given out to New Brunswickers, and New Brunswickers are asking questions to their MLAs," says Liberal Leader Roger Melanson. Opposition Liberal leader Roger Melanson (CBC News) In January, Higgs said many more New Brunswickers could be vaccinated each week, if only there were enough vaccine. Now those supplies are ramping up fast. New Brunswick received 11,760 doses last week and a similar number is expected this week. Melanson says those doses should be administered as quickly as they arrive. "We're seeing deliveries, much bigger deliveries than what we had been getting since January, so now the onus has shifted onto the provincial governments," says political scientist Stéphanie Chouinard of the Royal Military College in Kingston, Ont. Deputy minister of Health Gérald Richard told the legislature's public accounts committee Feb. 24 that New Brunswick would be ready for what he called "a flood" of vaccines, including those from AstraZeneca and Johnson & Johnson. "We are very confident that we have a good plan in New Brunswick," Richard said. "It was approved by the COVID cabinet and ratified by cabinet a few months ago."

And officials have given varying estimates of how many people can be vaccinated per week. In January, when deliveries to the province were still a trickle, Premier Blaine Higgs said 45,000 could be done, if only the province had enough vaccine. On Thursday he told reporters the province could do 40,000, then added it might be possible to double that to 80,000. Last Saturday, Health Minister Dorothy Shephard told CBC's The House that New Brunswick could vaccinate "up to 4,000 people a day," which works out to a maximum of 28,000 per week — below Higgs's estimate. Meanwhile, other provinces are moving faster, or at least providing more detail, on their rollouts. This week, Nova Scotia announced its plan for 13,000 doses of the AstraZeneca vaccine, the third to be approved in Canada. A health worker holds up a dose of the AstraZeneca vaccine against COVID-19.

New Brunswick has provided no such detail on what it will do with the approximately 10,000 doses it will receive. Higgs says that will be discussed by the all-party COVID cabinet committee next Tuesday and spokesperson Shawn Berry said the province will probably use it for some of the groups identified for early vaccination. Berry said 3,200 people were scheduled to be vaccinated this week but some clinics were delayed because of winter weather. He said doses listed as "available" by the province — more than 13,000 as of Thursday — are earmarked for clinics. "To prevent the risk of disruption of clinics, we don't plan to use them the same week they are scheduled to arrive in case there is a delay," he said. As an example, he said the province received more than 11,000 doses last week and a similar amount will be used at First Nations clinics that started this week. Berry also said Higgs's figure of 80,000 vaccinations per week being possible is correct. Higgs said last Friday one reason for the lack of detail is the uncertainty of supply that plagued the provinces for the first two months of the year. "When we schedule appointments, we will have a vaccine to put with it," he said during last week's CBC political panel on Information Morning Fredericton. "I would like to see a map out over the next two or three or four months of a fixed quantity so that we can plan well." Not when, but how Melanson said he's satisfied with the "who" and "when" so far but wants to know about the "how" — how people will contact, or hear from, the province to arrange their shots. At the Feb. 24 public accounts committee meeting, Liberal MLA Jean-Claude d'Amours also pointed to a Brunswick News report that the province was "urgently" calling for help in long-term care homes from anyone qualified to administer vaccines — another sign of lack of preparedness, he said. Whether New Brunswick's plan is really behind other provinces remains to be seen. The fluctuations in vaccine deliveries to Canada caused short-term alarm and a lot of political finger-pointing but in the end did not endanger the overall vaccine delivery target for the first three months of 2021. Still, Chouinard points out that even those temporary delays probably led to more illness and deaths. D'Amours noted at the public accounts committee that the percentage of COVID-19 doses the province was administering was slipping. Liberal health critic Jean-Claude d'Amours(CBC) The week before the hearing, 21 per cent of all doses received in New Brunswick hadn't been used. It rose to 25 per cent last week and 28 per cent this week. "Supply is not the issue right now," Melanson says. "The issue is capacity to roll it out." The province has been holding back a lot of vaccine for second doses. But with the recent announcement that second doses will be delayed to maximize first doses, those hold-back numbers should now diminish. On Thursday the Nova Scotia and Prince Edward Island governments said the delay to second doses will allow everyone in those provinces who wants to be vaccinated to get their first dose by June. Higgs told reporters that's his target as well. He said more details on how delayed second doses and new vaccine approvals will change the province's rollout plan should be coming next week. Berry said 7,503 of 11,000 long-term care residents have received at least one dose of vaccine and first-dose clinics for all long-term care facilities will be finished over the next two weeks.
