The expiry dates on millions of Covid vaccine doses to be extended.
VAAL TRIANGLE - Pfizer has applied to extend expiry dates on 7-million Covid vaccine doses. The South African Health Products Regulatory Authority assured the public of the safe extension of the vaccine’s shelf life - after receipt of the application. By conducting stability studies, vaccines can have their shelf life prolonged without recall. Compliance with storage requirements remains crucial. While South Africa’s vaccine drive has slowed due to low public demand, the country benefits from extensive infection-induced immunity.
