Gan droi at hunanynysu, fel y nododd y Prif Weinidog ar 14 Gorffennaf, cytunwyd, o heddiw ymlaen, nad oes rhaid i bob oedolyn sydd wedi’i frechu'n llawn gyda brechlynnau COVID-19 y GIG a phobl ifanc o dan 18 oed hunanynysu ar ôl iddynt ddychwelyd o wledydd ar y rhestr oren. Yr eithriad i hyn yw Ffrainc. Wrth gyrraedd yn ôl o Ffrainc bydd rhaid i bobl hunanynysu am 10 diwrnod, hyd yn oed os ydynt wedi’u brechu'n llawn. Y rheswm dros hyn yw pryderon am amrywiolyn Beta y deellir ei fod yn osgoi ein brechlynnau'n haws.  Mae cael eich brechu’n llawn yn golygu bod pythefnos wedi mynd heibio ers ichi gael eich dos terfynol o frechlyn cymeradwy o dan raglen frechu’r DU, eich bod yn cymryd rhan mewn treialon clinigol brechlyn COVID-19 a gymeradwywyd yn ffurfiol, neu eich bod o dan 18 oed ac yn byw yn y DU.
Turning to self-isolation, as the First Minister set out on 14 July, it has been agreed that, from today, all adults who are fully vaccinated with NHS COVID-19 vaccines and under-18s, do not have to self-isolate on their return from amber-list countries. The exception to this is France, from where on arrival people will continue to be required to self-isolate for 10 days, even when fully vaccinated. This is because of concerns about the Beta variant which is understood to more easily evade our vaccines. Fully vaccinated means that two weeks have passed since you have had your final dose of an approved vaccine under the UK vaccination programme, are taking part in formally approved COVID-19 vaccine clinical trials, or under the age of 18 and resident in the UK.
