We are also encouraging students to complete their full course of two doses before returning to university and college in September to make sure they are as protected as possible.
Rydym hefyd yn annog myfyrwyr i gael eu cwrs llawn o ddau ddos cyn dychwelyd i’r brifysgol neu i’r coleg ym mis Medi i wneud yn siŵr bod ganddynt yr amddiffyniad gorau posibl.
