The Quebec government says it is confident a "large majority" of health-care workers will comply with its mandatory vaccination policy, even if tens of thousands still haven't gotten a jab.

Roughly 30,000 staff in the private health system and 25,800 in the public system remain unvaccinated, the Ministry of Health said in a statement on Wednesday.

Among the public sector, 92 per cent of workers have received one dose and 88 per cent have received two. The Health Ministry did not provide a breakdown for workers in the private sector.
