Millions of COVID-19 doses to expire this year in Canada. How will they be used? – National | 24CA News
At least 19 million doses of COVID-19 vaccines are set to run out by the top of the 12 months in Canada, in line with knowledge obtained by The Canadian Press.
The federal central stock at present has 18.5 million doses in inventory, with 16.8 million of these bearing 2023 expiry dates, the Public Health Agency of Canada mentioned.
There are greater than eight million further doses in provincial and territorial stockpiles, in line with knowledge offered by ministries and departments of well being throughout the nation.
Those numbers present greater than two million of the provincial and territorial doses will expire by the top of the 12 months.
However, that’s seemingly an underestimate as a result of Ontario, New Brunswick and P.E.I. didn’t disclose the proportion of their doses that will expire by year-end. Ontario alone has 4.8 million COVID-19 vaccine doses in its provide.
“The Government of Canada, along with provinces and territories, will continue efforts to optimize its COVID-19 vaccine supply management and further reduce COVID-19 vaccine surpluses and wastage,” a spokesperson for the Public Health Agency of Canada mentioned in an e-mail.
Some of these doses, for instance, may very well be utilized in COVID-19 vaccine campaigns if the National Advisory Committee on Immunization (NACI) recommends additional booster photographs “based on evolving scientific evidence.”

With hundreds of thousands of COVID-19 vaccine doses wasted, has Canada stored its donation guarantees?
A fall booster shot marketing campaign for the final inhabitants is “likely,” mentioned Dr. Matthew Miller, director of the DeGroote Institute for Infectious Disease Research at McMaster University.
NACI’s present spring suggestions are focused at extra susceptible teams. They embody booster photographs for individuals age 65 and older, in addition to others at excessive threat of extreme sickness, if it’s been six months or extra since their final shot or a COVID-19 an infection.
About 6.7 million of the doses within the federal stock are bivalent COVID-19 vaccines, which particularly goal the Omicron variant and are really helpful for booster photographs. Data from the provinces and territories present that a big portion of their vaccine provides are bivalent doses.
A provide of non-bivalent vaccines remains to be wanted for individuals getting vaccinated for the primary time (main collection of photographs) and for kids below 5 years of age, well being officers throughout the nation say. More than 80 per cent of Canadians have accomplished their main collection of COVID-19 vaccination.
Canada additionally “stands ready” to donate surplus COVID-19 doses to growing international locations, Global Affairs Canada mentioned in an e-mail to The Canadian Press.
But it acknowledges that many lower-income international locations both aren’t asking for COVID-19 vaccines as a lot as they have been earlier within the pandemic, or theydon’t have the flexibility to get the photographs into individuals’s arms.
“The global landscape has shifted from a period of limited supply to one where vaccine supply currently exceeds demand and administration capacity,” Global Affairs Canada mentioned.
“The current challenge is therefore not supply, but delivery, distribution and demand in country.”
Plus, the clock is ticking for donating doses because the expiry dates method.
“Recipient countries typically request vaccines with at least six months of shelf life, which is considered to be a reasonable timeline that allows for planning rollout,” mentioned a spokesperson for GAVI, the worldwide vaccine alliance that helps oversee COVID-19 vaccine donations, in an e-mail.
So far, Canada has donated greater than 25 million doses which have been shipped to 30 international locations, the GAVI spokesperson mentioned.
Another potential choice to attenuate vaccine wastage is expiry date extensions by vaccine producers which can be authorized by Health Canada.
That has already occurred in P.E.I., mentioned Morgan Martin, a spokesperson for the province’s Department of Health and Wellness.
“The vaccines in our current inventory have varying expiry dates, and are updated if and when the manufacturer is granted an extended expiry date,” she mentioned in an e-mail.
“For example, the current Pfizer infant and Pfizer pediatric vaccine expiry dates were extended and now do not expire until 2024.”
To decide if a vaccine remains to be efficient past the unique expiry date, producers do “stability testing,” mentioned Mina Tadrous, an assistant professor of pharmacy on the University of Toronto.
“A manufacturer basically lets something age and then tests it in a certain environment,” Tadrous mentioned. Those exams take elements reminiscent of refrigeration into consideration when figuring out if there are circumstances the place the expiry date may be prolonged.
Because COVID-19 vaccines have been new merchandise made in response to an pressing pandemic, there was no approach to know the way lengthy they will really final in order that they got “really tight” expiry dates, he mentioned.
As time passes, researchers can see how lengthy and below what situations vaccine and drug formulations final, Tadrous mentioned _ and expiry dates may very well be revised in session with Health Canada.
Despite efforts to make use of as a lot of the COVID-19 vaccine provide as attainable earlier than it expires, there’s going to be waste, each Tadrous and Miller mentioned.
But that’s not stunning given the complexities of making an attempt to guard individuals and predict vaccine uptake throughout a pandemic, they mentioned.
“From a domestic standpoint, we would far rather have the problem of having too many vaccines than too few,” Miller mentioned.
