Mae’r dull hwn yn cyd-fynd â’r dull a ddefnyddiwyd mewn rhaglenni eraill (fel y rhaglen ffliw tymhorol), a’r dull yng ngwledydd eraill y DU ar gyfer rhaglen frechu Covid-19 y gwanwyn. Os yw rhywun sy’n gymwys i gael brechiad atgyfnerthu’r gwanwyn wedi cael haint Covid-19 yn ddiweddar, bydd angen iddynt aros 28 diwrnod neu bedair wythnos o’r dyddiad y cawsant brawf positif cyn y gallant gael eu brechu. Byddant yn gallu cael eu brechu ar ôl 30 Mehefin fel rhan o’r ymgyrch hon os oes angen iddynt ohirio eu brechiad.
This approach is consistent with the approach used in other programmes (like seasonal flu), and in other UK nations for their spring Covid-19 programme. If someone eligible for a spring booster has had a Covid-19 infection recently, they will need to wait 28 days or four weeks from the date they tested positive before they can be vaccinated. They will still be able to get vaccinated after 30 June as part of this campaign if they have to postpone their vaccination.
