COVID-19 vaccines would still be safe and effective, despite having their expiry date extended by a month.In a statement Saturday, Health Canada said the expiry date of two lots of the AstraZeneca vaccine has been extended from May 31 to July 1.“The approval to extend the shelf life was supported by scientific evidence,” the statement reads.
Health Canada had previously approved a six-month shelf-life for the shot.However, the agency said on Thursday it received a submission from AstraZeneca that “included product stability and mathematical modelling data that demonstrated that the quality, safety and efficacy of the two lots would be maintained for an extra month, for a total of up to seven months.” Health Canada extends expiration date.
