Ontarians cancelling AZ doses after new guidance, province still offering dose choice

The use of the Astra Zeneca vaccine for second doses is permitted in Saskatchewan

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.

Ontarians who got a first shot of Oxford-AstraZeneca were cancelling appointments for second doses of that vaccine following new guidance from a national advisory group, pharmacists dealing with scrapped bookings said Friday. The company is the second-largest pandemic vaccine supplier to the European Union, behind Pfizer, which so far has provided 233 million doses of its vaccine compared to AstraZeneca's 66 million.

"All COVID-19 vaccines available in the province, including AstraZeneca, have been determined to be safe and effective by Health Canada, and have been shown to prevent serious illness, hospitalization and death associated with COVID-19", Hilkene said in a statement Friday.

VITT is a rare blood clot that has occurred in some people who received the AstraZeneca shot.

Bates said pharmacies will now need more supply of mRNA vaccines to meet what he expects will be increased demand for those shots.

After AstraZeneca-related blood clotting appeared around the world in young people, Henry suspended use of that vaccine for people aged under 30.

From the beginning, the Commission has claimed that it launched the emergency legal procedure, which started at the Brussels Court of First Instance last month, simply to secure the vaccine doses that European Union member countries were promised.

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.

Ontario has administered more than 12.1 million doses of COVID-19 vaccines so far and is further expanding second-dose eligibility next week.

Moderna has only made up 17 per cent of deliveries in B.C., with 787,140 doses, however Henry said close to a million doses of that vaccine were expected over the next month.

This is fortuitous, as Pfizer deliveries in July will be significantly less than earlier promised.

"That is something that happens when we're in a global pandemic with a global vaccine supply. We don't know that definitively, and we may not know that for some time".

There are no further shipments of AstraZeneca now scheduled, but there are about 600,000 doses still left from previous deliveries. There are 1,320 active cases of COVID-19 in the community and 131 being treated in hospital, of which 44 are in intensive care. 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.
