Yn y cyfamser, roeddwn am hysbysu'r Aelodau o'm penderfyniad i ddilyn cyngor pedwar Prif Swyddog Meddygol y DU i roi blaenoriaeth i'r dosiau cyntaf, tan hyd at 12 wythnos o'r dos cyntaf i'r ail apwyntiad. Bydd apwyntiadau ar gyfer ail ddos a drefnir o yfory ymlaen o fewn 12 wythnos i'r dos cyntaf, sy'n golygu y dylai adnoddau gael eu hailneilltuo ar gyfer dosiau cyntaf.
In the meantime, I wanted to inform Members of my decision to follow the advice of the four UK Chief Medical Officers to prioritise first doses, to up to 12 weeks from first dose to re-appointment. Second dose appointments given from tomorrow will be within 12 weeks from the first dose, which means capacity should be reappointed to first doses.
