Yn ystod ymgyrch pigiad atgyfnerthu y gwanwyn, mae grŵp o bobl wedi eu nodi yn anghywir fel pobl sy’n gymwys i gael brechiad ychwanegol. Golyga hyn fod mwy o bobl nag yr oedd y Cyd-bwyllgor ar Imiwneiddio a Brechu (JCVI) wedi bwriadu yn wreiddiol iddynt fod yn gymwys i gael y pigiad atgyfnerthu naill ai wedi cael y brechiad, wedi cael gwahoddiad i’w gael neu’n mynd i gael gwahoddiad i’w gael.
During the course of the spring booster campaign, a group of people have been identified incorrectly as being eligible for an additional vaccination. This means that more people than the Joint Committee on Vaccination and Immunisation (JCVI) initially intended to be eligible for the booster have either received, been invited or are due to receive an invite for vaccination.
