BARRHEAD, Alta. - Alberta Health Services says some vaccines given last year in the Aspen Health Region may not provide adequate protection.
Health services says during a routine check, it was found some vaccines had been exposed to storage temperatures outside the recommended levels.
The vaccines were given to clients in Barrhead, Mayerthorpe, Onoway, Swan Hills, Thorhild, Lac La Biche and Westlock.
Health Services says it's conducting assessments on an individual basis to find out which clients should be re-immunized, and are contacting those affected.
A review of the vaccine storage process is underway.
