As of Sunday, eligibility in the provincial age based immunization program moved to 20 years of age and older. For residents in the Northern Saskatchewan Administration District the eligibility age is 18 and older. This applies to all immunization clinics whether it is booked appointments, pharmacies, drive-thru/walk-in and mobile. And also as of Sunday the SaskVax Call Centre was moving to seven days a week operating, from 8 a.m. to 9 p.m. with the reminder to residents that clinic availability is based on vaccine availability and right now demand for appointments outweighs the current vaccine supply.
