KATHMANDU: British Columbians who chose to get a first dose of AstraZeneca should not get it for their second dose and instead get the Pfizer or Moderna vaccine, a key federal advisory committee said Thursday.
Previously, the National Advisory Committee on Immunization said AstraZeneca recipients could choose whether to get a second dose of the same vaccine, or an mRNA vaccine (Pfizer or Moderna). But in new guidance released Thursday, NACI says Pfizer or Moderna are now “preferred” as the second dose.

In B.C., AstraZeneca was rolled out in March and April during the third wave of the pandemic as a way to immunize high-risk workers and people not yet eligible through the age-based rollout that mostly used Pfizer.
After AstraZeneca-related blood clotting appeared around the world in young people, Henry suspended use of that vaccine for people aged under 30. Around 280,000 British Columbians received a first dose of AstraZeneca vaccine. National figures as of June 5 show that 2.1 million people in Canada had received a first dose of AstraZeneca, but fewer than 16,000 had received it as a second dose.
According to Canada’s COVID-19 vaccine rollout plan, B.C. received 438,000 doses of AstraZeneca – or just under 10 per cent of the total number of doses delivered across the province.
By far, Pfizer is the most available vaccine in the province – with 3,385,590 doses delivered.
Moderna has only made up 17 per cent of deliveries in B.C., with 787,140 doses, however Henry said close to a million doses of that vaccine were expected over the next month.
This is fortuitous, as Pfizer deliveries in July will be significantly less than earlier promised.
“Today we were notified that there’s some upcoming challenges with the deliver of Pfizer vaccines in July, and as a result, the supply that we’ll be receiving in the first two weeks of July is now reduced,” Henry said.
“That is something that happens when we’re in a global pandemic with a global vaccine supply. We know these speed bumps happen, and while disappointing, they’re not unexpected, given the complexity of the global immunization efforts.
