Canada vaccine panel recommends against AstraZeneca for second dose

After another change on recommendations from the National Advisory Committee on Immunization (NACI) for people who received a first dose of the AstraZeneca vaccine, some Windsor residents remain unconcerned with their choice to get the second dose of that vaccine.

The premier of British Columbia received a second dose of AstraZeneca's COVID-19 vaccine on Friday, following updated national immunization recommendations that have left some Canadians scratching their heads.

Still, some B.C. pharmacies that are now administering second doses of AstraZeneca vaccine said they have received a wave of cancellations since the announcement.

The use of the AstraZeneca vaccine for second doses is permitted in Saskatchewan.

"If they told me I took two AstraZeneca and I'm protected, I'm protected, I'm not anxious at all", Harshaw says. "There is no need for a third dose at this time".

One of those studies from Germany's Saarland University, published early data Wednesday saying giving Pfizer as the second dose after AstraZeneca, or two doses of Pfizer only, generated far more antibodies and T cells as two doses of AstraZeneca.

"If you had AstraZeneca for your first dose, you can safely take either AstraZeneca, Moderna or Pfizer for your second dose for strong protection", Alexandra Hilkene, a spokeswoman for Health Minister Christine Elliott said in a statement. 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.

The court said in a statement that AstraZeneca must deliver 15 million doses by July 26, another 20 million by August 23 and another 15 million by September 27, for a total of 50 million doses.

After winning emergency approvals, the vaccine launch ran into supply shortfalls and safety concerns over rare blood clots following vaccination.

There are no further shipments of AstraZeneca scheduled.

After a sluggish start earlier in the year, Canada has sharply increased its administration of Covid-19 vaccines in recent months.

A Belgian court ruled Friday that coronavirus vaccine-maker AstraZeneca had committed a "serious breach" of its contract with the European Union amid a major legal battle over delivery obligations that has tarnished the company's image. All three have been approved for safe use in Canada. 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.

"AstraZeneca has fully complied with its agreement with the European Commission and we will continue to focus on the urgent task of supplying an effective vaccine".
