Health Canada has directed provinces to withdraw and destroy remaining supplies of last year's COVID-19 vaccines while it works to authorize updated shots, which is expected to happen in October, according to Ontario鈥檚 health ministry.
鈥淰accines will be available once Ontario receives supply from Health Canada following their regulatory authorization of the new, updated vaccine formulation," read a statement from Ontario spokesperson Hannah Jensen.
A notice posted on the federal government鈥檚 says vaccines aimed at Omicron variant XBB.1.5 is no longer available in Canada. Updated shots, made to target the now-dominant JN.1 or KP.2 strains are expected to get the green light 鈥渋n the coming weeks.鈥�
Meanwhile, COVID-19 is spreading quickly and widely across Canada, and suggest.
Alberta's health ministry has confirmed old-strain COVID-19 vaccines are no longer available. Quebec鈥檚 public health director told CTV News current stockpiles are to be returned to Ottawa. Saskatchewan has disposed of their Moderna Spikevax XBB.1.5 and Pfizer Comirnaty XBB.1.5 vaccines in anticipation of new doses.
"It is estimated Ontario, and other provinces, will receive supply from Health Canada in October," Jensen added.
CTV News has sought further comment from Health Canada on what it will do to remedy what appears to be a widespread gap in access to vaccines. The agency told CTV News Calgary that the swap should be timed so that there is uninterrupted access to shots.
In a statement, a spokesperson told CTVNews.ca that public health is working on a vaccine transition plan with provinces and territories, adding that it鈥檚 in talks with those governments 鈥渢o ensure common understanding of the transition.鈥�
The agency also says it maintains a federal reserve of XBB vaccines to respond to 鈥渁ny unexpected health need.鈥�
