Canada said on Friday that Pfizer’s decision to temporarily cut shipments of some Covid-19 vaccines was unfortunate but should not hit its inoculation program, Reuters reports.

Pfizer said it would slow production in late January to early February due to changes in manufacturing processes to boost production.

“This is unfortunate. However, such delays and issues are to be expected when global supply chains are stretched well beyond their limits,” Procurement Minister Anita Anand said, confirming that Canada would be affected.

Anand said that despite the delay, Canada was still on track to offer vaccines to everyone by the end of September. The country is struggling to contain a second wave of Covid-19.
