South African/Pfizer contract "Safe and Effective?"

 Contract 30 March 2021.
That's 3 months into the injection program worldwide.
So as of March 2021 Pfizer is stating that "the product is aspirational in nature and subject to significant risks and uncertainties."
Yet the mantra of "Safe and Effective" was forced on populations by politicians and health services.
