Dywedodd yr Ysgrifennydd Iechyd, Vaughan Gething: "Rwy'n falch iawn bod gwasanaethau iechyd rhywiol Cymru wedi manteisio ar y cyfleoedd y gall PrEP eu cynnig, ac mae canlyniadau cychwynnol yr astudiaeth yn galonogol iawn. Ni chafwyd unrhyw adroddiadau am achosion newydd o HIV ymysg y rhai sydd wedi dechrau cymryd y feddyginiaeth.
Health Secretary, Vaughan Gething, said: “I am pleased that sexual health services in Wales have embraced the opportunity that PrEP provides and the early results from the study are encouraging. No new cases of HIV have been reported in those who have started taking the medication.
