From the independent on certification....
The Department for Health and Social Care (DHSC) says the certification will be in line with the interim guidance on digital vaccine certification from the World Health Organisation (WHO).
The WHO requirements are highly specific, requiring for each jab:
The brand of vaccine and the name of the manufacturer.
The vaccine batch number **
The name of the vaccination facility **
The name of the health worker who administered the jab **
On paper certificates, the handwritten signature from “the health worker who provided the vaccination or the supervising clinician” **
The ones with ** next to them denote information that I don't think we have or our GP has from the trial.
