Er nad yw’n ailgyflwyno’r cyngor i ddilyn mesurau gwarchod, mae Prif Swyddog Meddygol Cymru wedi cydnabod y bydd rhai pobl yn y grŵp hwn yn pryderu am y cynnydd mewn achosion. Bydd rhai pobl sy’n agored i niwed efallai’n teimlo’n bryderus am y lefel o ymateb i’r brechlyn yn eu hachos penodol nhw oherwydd bod eu system imiwnedd yn wannach na’r cyffredin. Bydd eraill wedi methu â chael y brechlyn oherwydd eu cyflwr meddygol. I roi rhywfaint o sicrwydd iddynt, bydd Prif Swyddog Meddygol Cymru yn ysgrifennu at bawb ar y rhestr o gleifion a warchodir. Mae cynnwys y llythyr ynghlwm wrth y datganiad hwn. Mae’r llythyr yn nodi gwybodaeth am effeithiolrwydd y brechlyn, gan annog pobl i fanteisio ar y cynnig i gael brechiad os nad ydynt eisoes wedi gwneud hynny. Mae’r llythyr hefyd yn pwysleisio bod cael y ddau ddos yn hollbwysig, ac mae’n rhoi cyngor ar sut i leihau risg bersonol. Yn ogystal, mae’n nodi’r mesurau y bydd Llywodraeth Cymru yn eu cadw fel gofynion cyfreithiol ar lefel 0. (Dyma’r lefel y mae Llywodraeth Cymru wedi’i nodi fel y lefel cyn agosed i normalrwydd ag yr ydym yn debygol o’i chyrraedd am gyfnod.) Mae disgwyl i lefel 0 ddechrau ar 7 Awst os bydd yr amodau’n ffafriol. Mae’r wybodaeth hon wedi’i chynnwys er mwyn i’r rhai sy’n gweld newyddion o gyfryngau’r DU wybod y bydd rheolau gwahanol mewn grym yng Nghymru ac y bydd mwy o fesurau diogelu yma.
Despite not reintroducing the advice to follow shielding measures, the Chief Medical Officer for Wales has recognised that some people in this group will feel concerned at seeing the rising number of cases. There are people who are particularly vulnerable who may feel concerned about the level of response to the vaccine in their particular cases because of a known weakened immune system. There may be other people who have been unable to take the vaccine due to their medical condition.  To provide some reassurance, the Chief Medical Officer for Wales will be writing to all those on the shielding patient list. The content of the letter is attached to this statement. The letter includes information about vaccine effectiveness and encourages those who have not yet taken up the offer to do so, it also emphasises the importance of receiving both doses. In addition to this the letter provides advice on how to minimise personal risk and highlights the measures that the Welsh Government will be retaining as legal requirements at level 0. (The level which the Welsh Government has indicated will be as near to normal as we are likely to reach for a while.) Level 0 is expected to start on 7thof August if conditions are favourable. This information has been included to ensure that those who receive news from UK media outlets know that different rules will apply in Wales and there will be more protections here.
