Dr Frank Atherton said it could be towards the end next year before a vaccine was rolled out fully to all the eligible population and in the meantime it is essential that everyone continues to observe social distancing, limit meeting in indoor spaces, wear face coverings where appropriate and practice good hand and cough hygiene.



> This is an important step and a remarkable scientific achievement. But full safety data is needed before the vaccine is approved for use, he said.
> 
> 
> We have well\-developed plans to roll out any approved vaccine across priority groups in Wales, but in the meantime, we all need to continue doing everything we can to continue to prevent the spread of coronavirus.
> 
> 
> Limiting indoor visits, keeping our social distance, and wearing a face covering where needed as well as regular hand washing are vital actions if we are to suppress the spread of the virus in Wales. Continue to ‘stay safe’ and protect yourself and others.


The Welsh Government has been working closely with the UK Government and other devolved nations on preparing for vaccines in development.


Dr Atherton said:



> Planning for the delivery of a potential COVID\-19 vaccine in Wales is well underway. Including organising the logistics for transporting the vaccine, identifying suitable venues for vaccinations to take place, and ensuring that healthcare professionals are available and trained to administer the vaccines.
> 
> 
> Health and social care workers, care home residents and staff have been prioritised to receive a vaccine first, with roll out to older people in age bands from next year.
> 
> 
> But it’s likely to be a long time until the whole population has been vaccinated, so until then we should all be doing whatever we can to stop the spread of the virus.

Dywedodd Dr Frank Atherton y gallai fod yn nes at ddiwedd y flwyddyn nesaf cyn y bydd y brechlyn ar gael i’r holl boblogaeth gymwys, ac yn y cyfamser, mae’n hanfodol bod pawb yn parhau i gadw pellter cymdeithasol, cyfyngu ar ymgynnull dan do, gwisgo gorchuddion wyneb lle y bo’n briodol a chynnal arferion hylendid da wrth beswch ac o ran golchi dwylo.



> Dyma gam pwysig ac mae’n gamp wyddonol ryfeddol. Ond mae angen data llawn ar ddiogelwch cyn y gall y brechlyn gael ei gymeradwyo i’w ddefnyddio”, dywedodd.
> 
> 
> Mae gennym gynlluniau datblygedig i gyflwyno unrhyw frechlyn sydd wedi’i gymeradwyo i grwpiau blaenoriaeth yng Nghymru, ond yn y cyfamser, mae angen i bob un ohonom barhau i wneud popeth posibl i atal y coronafeirws rhag lledaenu.
> 
> 
> Mae cyfyngu ar ymgynnull dan do, cadw pellter cymdeithasol, a gwisgo gorchudd wyneb lle y bo angen, yn ogystal â golchi dwylo’n rheolaidd yn gamau hollbwysig os ydym am atal y feirws rhag lledaenu yng Nghymru. Mae angen i bawb barhau i ‘gadw’n ddiogel’ a diogelu eich hun ac eraill.


Mae Llywodraeth Cymru wedi bod yn gweithio’n agos gyda Llywodraeth y DU a’r gwledydd datganoledig eraill i baratoi ar gyfer y brechlynnau sy’n cael eu datblygu.


Dywedodd Dr Atherton:



> Mae’r gwaith cynllunio ar gyfer brechlyn COVID\-19 posibl yng Nghymru yn mynd rhagddo’n dda. Mae hynny’n cynnwys trefnu’r logisteg ar gyfer cludo’r brechlyn, chwilio am leoliadau addas ar gyfer rhoi’r brechlynnau, a sicrhau bod gweithwyr iechyd proffesiynol ar gael, ac wedi’u hyfforddi i roi’r brechlyn.
> 
> 
> Gweithwyr iechyd a gofal cymdeithasol, a phreswylwyr a staff cartrefi gofal sydd wedi cael blaenoriaeth i dderbyn y brechlyn gyntaf, ac yna bydd yn cael ei gyflwyno i bobl hŷn o wahanol grwpiau oedran o’r flwyddyn nesaf ymlaen.
> 
> 
> Ond mae’n debygol o fod yn amser hir tan bydd y boblogaeth gyfan yn gallu cael ei brechu, felly tan hynny, dylai pob un ohonom wneud popeth posibl i atal y feirws rhag lledaenu.
