COVID-19: Second dose of AstraZeneca vaccine no longer recommended in Canada

Pfizer, Moderna vaccines now preferred second dose for AstraZeneca recipients: NACI

"People who have received their first dose are likely to never go to the ICU even if they contract COVID-19", Masri said.

New advice has emerged out of the the National Advisory Committee on Immunization (NACI) that the "preferred" second vaccine for those who took AstraZeneca or the equivalent COVIDSHIELD would be an mRNA vaccine - Pfizer or Moderna.

Those who got a first shot of the vaccine have to wait at least eight weeks before getting a second shot of Pfizer, Moderna or AstraZeneca.

On Thursday, it changed its advice to recommend against the use of AstraZeneca's vaccine in most cases.

The ruling said that AstraZeneca had not lived up to commitments to use its "best reasonable efforts" to fulfill its contract to the E.U. The company had used its production site in Oxford, England, for doses only for Britain, which is no longer in the E.U. The vaccine was developed along with the University of Oxford.

"It's based on the better treatment option that's available, it has nothing to do with any kind of harm to anyone", says Windsor-Essex County Health Unit medical officer of health, Dr. Wajid Ahmed.

"If you had Moderna or Pfizer for your first dose, you can safely take either Moderna or Pfizer for your second dose for strong protection".

Another 210,638 shots of a COVID-19 vaccine were administered Thursday for a total of nearly 12.2 million doses. Almost 66% of the population had received at least one dose of a Covid-19 vaccine as of June 16, although just 15% of the population is fully vaccinated.

"This will open to approximately 2.1 million people in that 50 to 59 group who have not yet had vaccinations". Instead of the 300 million doses Europe sought by the end of September, the court ordered AstraZeneca to ship 80.2 million doses.

The donation won't cost Canada anything, and will be on top of the 44 million doses Canada has purchased directly from Moderna.

It comes less than a week after Canada promised to donate 13 million doses to the COVAX vaccine-sharing alliance, which will entirely come from the remaining share of doses Canada had purchased from COVAX itself. The World Health Organization has made repeated pleas for wealthier countries to share more doses with developing countries, some of whom have vaccinated very few people at all.

We would expect the number of people that are fully vaccinated with Sinopharm to be higher than with AstraZeneca eventually. Across Africa, nations have given out three doses for every 100 people.

"Taking vaccines at a time when we are nearing complete vaccination when many developing countries are so far behind makes Canada a vaccine hoarder and leaves Canadians vulnerable to unsafe variants", said NDP health critic Don Davies.
