Brechlyn Pfizer Biontech yw’r brechlyn cyntaf i gael cymeradwyaeth yr MHRA yn y Deyrnas Unedig. Bydd 40 miliwn dos o’r brechlyn ar gael cyn bo hir i’w dosbarthu ledled y DU, a bydd Cymru yn cael ei dyraniad yn ôl ei phoblogaeth.
The Pfizer Biontech vaccine has become the first to receive MHRA clearance in the UK and 40 million doses of the vaccine will shortly be available for delivery across the UK, with Wales getting its allocation based on population.
