Ar 16 Mai, sylwodd y byrddau iechyd ar anghysondeb posibl rhwng y meini prawf cymhwysedd a bennwyd gan JCVI a’r bobl a oedd yn dod i gael eu brechu. Daeth fy swyddogion yn ymwybodol o hyn ar 17 Mai ac rydym wedi gweithio gydag Uned Gyflawni y Gwasanaeth Iechyd Gwladol (GIG), y byrddau iechyd, Iechyd a Gofal Digidol Cymru ac Iechyd Cyhoeddus Cymru i ymchwilio ymhellach i’r mater.
On 16 May, health boards identified a potential discrepancy between the eligibility criteria determined by the JCVI and those presenting for vaccination. My officials became aware of this on 17 May and we have worked with the NHS Delivery Unit, health boards, Digital Health and Care Wales (DHCW) and Public Health Wales to investigate the issue further.
