The federal government is donating 17.7 million doses of the Oxford-AstraZeneca COVID-19 vaccine and is asking Canadians to give their own money to help other countries get needles into arms.

Procurement Minister Anita Anand says after talking to provinces, it was determined these COVID-19 doses to be excess supply, as demand for this vaccine had been met.

She says the AstraZeneca doses to be donated were supposed to flow into Canada through an advanced purchase agreement and be produced in the United States.

Anand says the shots will be made available to lower-income countries through the global vaccine-sharing alliance COVAX. The timing is still being worked out.

The National Advisory Committee on Immunization says mRNA vaccines, such as the ones by Modernaand Pfizer-BioNTech, are preferred over the viral-vector vaccine by AstraZeneca, even for people who received AstraZeneca as a first dose.

Prime Minister Justin Trudeau was among the Canadians who got AstraZeneca for his first dose and Moderna for his second.

While at the G7 last month, Trudeau pledged Canada would give back 13 million doses it was set to receive through a contract with COVAX, on top of millions of dollars already set aside for the global vaccine effort.

Canada is on track to receive 68 million doses by the end of July, which would be enough to inoculate most Canadians.

At MondayB次元官网网址檚 announcement, Anand says 44 million doses of Moderna and 51 million shots from Pfizer-BioNtech are expected to have arrived in the country by the end of September.

With a population of nearly 38 million people, Canada would need about 76 million shots of two-dose vaccines to make sure everyone is fully vaccinated.

Asked Monday about why the federal government hasnB次元官网网址檛 marked any of its Moderna or Pfizer deliveries for donation given its volume of supply, Anand said these shots are still in high demand in Canada and things could stay that way.

B次元官网网址淲e are still watching the science evolve in this area in terms of the potential need for an additional third shot or boosters, and so we are making sure that we have the supply on hand of these vaccines to be able to serve the needs of Canadians in the short and the long term,B次元官网网址� she said.

B次元官网网址淎ny decision on the donation of doses needs to be made by the Public Health of Agency in co-ordination with the provinces and territories.B次元官网网址�

ItB次元官网网址檚 unclear when, or whether,Canadians will need to get a third dose of vaccine.

Pfizer said recently it has seen a bit of a dip in antibodies in Israel six months after vaccination and intends to ask the U.S. and Europe to approve giving a booster shot

A Pfizer Canada spokeswoman said itB次元官网网址檚 too early to comment on whether the company will ask the same of Canada.

Very few people in this country would hit six months fully vaccinated until closer to the end of the year.

Health Canada and the federal public health agency issued a joint statement last Friday saying the duration of protection from COVID-19 vaccines is still being studied but current data B次元官网网址渟hows good immunity in most people out to 9 months after receiving 2 vaccine doses.B次元官网网址�

The statement said the issue of needing boosters is top of mind for both organizations, and decisions will be based on scientific evidence. In April, Canada announced a deal to get 35 million booster shots from Pfizer in 2022, and another 30 million in 2023, in case they are needed.

To keep up with its commitment to help vaccinate less wealthy nations, theLiberal government also announced Monday it would match donations Canadians make to a UNICEF fundraising campaign called B次元官网网址淕ive a VaxB次元官网网址�, for a contribution of up to $10 million.

David Morley, the head of UNICEF Canada, says the money raised will pay for transportation and some of the other logistical needs required to deliver vaccines to people.

International Development Minister Karina Gould says sheB次元官网网址檚 heard Canadians want to help be part of the global COVID-19 vaccination effort.

B次元官网网址淎s Canadians are hearing more about the Delta and the Lambda variant, recognizing that if the pandemic continues to rage in other parts of the world, thatB次元官网网址檚 more opportunities for variants and mutations to emerge,B次元官网网址� she said in an interview with The Canadian Press.
