TORONTO -- Ontarians aged 40 and older can book COVID-19 vaccine appointments across the province today.

The province is opening eligibility to the age cohort through its vaccine booking portal.

People in their 40s could previously take Oxford-AstraZeneca shots at pharmacies and they can now book at other clinics.

The province stopped giving first doses of the AstraZeneca vaccine this week, citing risk of a rare but serious blood clot linked to the shot.

People with at-risk health conditions and more people who can't work from home also became eligible to book shots this week.

The province is expecting millions of vaccines in the coming weeks and is aiming to get first shots to 65 per cent of adults by the end of May.
