Bydd plant a phobl ifanc o dan 18 hefyd wedi’u heithrio rhag gorfod hunanynysu os cânt eu nodi’n gyswllt agos i achos positif. Ond bydd pawb sy’n profi’n bositif gyda’r coronafeirws neu sydd â symptomau yn dal i orfod hunanynysu am 10 diwrnod, p’un a ydynt wedi cael eu brechu ai peidio.
Children and young people under 18 will also be exempt from the need to self-isolate if they are also identified as close contacts of a positive case.  But everyone who tests positive for coronavirus or has symptoms must continue to isolate for 10 days, whether they have been vaccinated or not.
