Pfizer-BioNTech vaccine

The federal Conservatives are urging the Liberal government to do more to ensure that Canadians who received two different doses of COVID-19 vaccines are able to travel internationally.

The federal government is expecting to receive about 7.1 million doses of COVID-19 vaccines this week, as it adjusts its distribution strategy amid waning vaccination rates and substantial supply.

Chief public health officer Dr. Theresa Tam says the latest variant of interest in the COVID-19 pandemic has popped up in Canada in small numbers, but it's too early to know how widespread it is or what impact it could have.

Health Canada's latest weekly report on vaccinations shows at least 1.3 million Canadians opted for a mixed-dose finish to their COVID-19 vaccination schedule in June.

A vaccine study in the United Kingdom reports that getting a dose of the Pfizer-BioNTech vaccine four weeks after a dose of Oxford-AstraZeneca produced a much stronger immune response than two doses of AstraZeneca.

The latest recommendation from NACI has Canadians who chose AstraZeneca for both doses wondering if they did the right thing.

Canada is on the cusp of hitting its first national vaccination target, but chief public health officer Dr. Theresa Tam says the Delta variant of the virus that causes COVID-19 might mean the country has to up its vaccine game again.

A new study in England suggests even just one dose of the Pfizer-BioNTech and Oxford-AstraZeneca vaccines are extremely good at keeping people from ending up in the hospital if they contract COVID-19 from the Delta variant of the virus that causes it.

Prime Minister Justin Trudeau is spending the last day of his first international trip in more than a year visiting a plant that played a pivotal role in Canada's early rollout of the COVID-19 vaccine.

Prime Minister Justin Trudeau pledged 13 million surplus vaccines to help the world get immunized against COVID-19 as he and other G7 leaders wrapped up a weekend summit in Britain dominated by the pandemic, climate change and China.

A homegrown mRNA vaccine for COVID-19 shows promising results in its first small trial and its maker is hoping to test it directly against the vaccine from Pfizer-BioNTech.

Preliminary results of an ongoing study in the United Kingdom suggest alternating the Oxford-AstraZeneca and Pfizer-BioNTech vaccines causes more frequent mild to moderate symptoms, but there are no other safety concerns from mixing those vaccines.

In the last four years, Health Canada has approved more than 1,500 new or updated pharmaceuticals

Federal officials are "anxious" over new modelling showing an increase in daily COVID-19 cases, which they say comes at a bad time with several religious holidays nearing, and people wanting to gather with families.

Canada's COVID-19 vaccination drive is poised to shift into high gear this week as the federal public health agency prepares to take delivery of the largest number of doses since the launch of the immunization effort.
