World Health Organization re expiry dates on AstraZeneca:
'Any vaccine that has passed its expiry date, including Covishield, should not be administered.'
'While discarding vaccines is deeply regrettable in the context of any immunization programme, WHO recommends that these expired doses should be removed from the distribution chain and safely disposed.'
'The shelf-life of a vaccine is a reflection of how long the vaccine retains its potency and stability at a given storage temperature and therefore its effectiveness. The shelf-life is used to establish the expiry date of each batch of the vaccine product.'
'Expiry dates do not affect the safety of the vaccine, rather are related to the potency or amount of protection the vaccine gives.'

Ahem, Ontario: B.C. gov't on giving expired AstraZeneca vaccines to people:
The provincial Ministry of Health said in a statement that when expired vaccines are administered "in general, those who receive an expired vaccine should be advised, and recommended revaccination."
It also says the expired products should then be sequestered in the refrigerator and returned to public health for safe disposal.
'A video meant for training purposes on the B.C. Centre for Disease Control's website says "expired vaccine is wasted." Other BCCDC & Health Canada documentation on the AstraZeneca vaccine indicate that it should be used before the expiration date.'

No, the NACI recommendation is 'up to 4 months' because of the vaccine shortage, not '4 months.' The manufacturer recommendation is up to 3 months. I was told by pharmacy to book my 2nd dose after one month - book it, not get it - which has now gone to hell because of AZ shortage
The reason so many of us are trying to book it now is because we know that it's going to be almost impossible to do by the time the next substantial shipment of AZ to Ontario next week is 250,000 doses. More than a million Ontarians had AZ as their first dose.
See the problem?
Finally, where there is adequate supply -- not in Ontario for AZ -- provinces are already making plans, as they should, to reduce the interval between the 1st and second dose: B.C. to detail shortening interval between first, second COVID-19 vaccine doses: citynews1130.com/2021/05/27/bc-…

Sticking it to Canadians: 'Justin Trudeau has been bragging about vaccination rates. This self-congratulatory spin egregiously misrepresents the true vaccination picture: As of May 17 Canada actually ranked a shameful 2nd to last among G7 nations in fully vaccinating population'
'This is on par with nations such as St. Kitts and Nevis (3.3) and Kazakhstan (4.1).
Vaccine procurement in Canada has been a massive debacle.'
'In November 2020 it was revealed Pfizer and Moderna procurements had been delayed as a result of a deal gone bad between the National Research Council (NRC) and a Chinese supplier. After months of delays, China (a Trudeau favoured-nation) refused to ship the vaccine.'
