Canada Secures 20-Million More Doses of Pfizer Vaccine

Canada Secures 20-Million More Doses of Pfizer Vaccine

He also says that between now and sometime between April and June, Canada will have enough doses to vaccinate up to 20 million people against the deadly coronavirus.

After receiving a first batch of a COVID-19 vaccine from the U.S. pharmaceutical giant Pfizer and its German partner, BioNTech, Greece now will get 240,000 doses from the Boston-area firm Moderna.

"We are very confident that the vaccine will be much higher than 60%", he said, adding that the "aim is for the highest levels, hopefully closing in on what Moderna and Pfizer are doing".

Both the Pfizer-BioNTech and Moderna vaccines require two doses.

Quebec has chose to delay administering second doses to patients and has instead chosen to give a first dose to as many people as possible.

An Asda supermarket is to host a Covid-19 vaccination centre.

The World Health Organization has said waiting up to six weeks is acceptable, and several countries are doing this or are looking at the idea as desperate health regions try to get vaccines into as many people as possible, even if it's just one dose.

Dr. Bonnie Henry, B.C.'s chief public health officer, said this week that province can vaccinate another 150,000 vulnerable people by the end of March by using a 35-day dosing schedule.

Neither Pfizer nor Moderna endorse the idea of waiting for the second dose.

According to official figures Britain has administered 2.6 million first vaccine doses so far, and Hancock has said Britain is on track to meet its target and manufacturers were delivering on schedule.

Provinces led by premiers of all political stripes said they can administer more doses than they have received, or they will be given over the next few months. If results of ongoing studies suggest people would fare better with a second booster shot, Stoffels said J&J would file separately for a booster dose authorization. "So, you know, it's kind of a back-of-the-envelope calculation".

But that data is based only one or two weeks of monitoring before the second dose was given, and there is nearly no data to show whether that immunity began to wane at any point.

The study showed that 90% of 805 volunteers aged 18 to 55 developed protective antibodies 29 days after a single dose, and that increased to 100% by day 57.

NACI's recommendations say if the second dose is delayed those patients must be followed so more evidence of the impact can be attained.

Johnson & Johnson is on track to roll out its single-shot coronavirus vaccine in March, and plans to have clear data on how effective it is by the end of this month or early February, the USA healthcare company's chief scientific officer said.
