Mae pob sefydliad y GIG yng Nghymru wedi cynnal ymarferion ar draws y wlad i brofi ein trefniadau dosbarthu a storio, ac i sicrhau bod modd mynd â brechlyn effeithiol yn ddiogel i bob rhan o Gymru. Ar 26 Tachwedd, cynhaliwyd ymarferion ar draws GIG Cymru i brofi’r trefniadau i gludo’r brechlyn Pfizer o’r storfa ganolog ar dymheredd isel tu hwnt i gael ei ddefnyddio yn y pen draw i frechu unigolyn. Roedd yr ymarfer hwn yn dilyn prawf cychwynnol ar 12 Tachwedd, gan ehangu’r trefniadau i gynnwys sawl safle a’r holl ddeunyddiau cysylltiedig angenrheidiol i gynnal clinig brechu.
All NHS organisations in Wales have undertaken Wales-wide simulation exercises to test our distribution and storage arrangements and to ensure we can get effective vaccine safely to every part of Wales. On 26 November, the end to end logistics for the Pfizer vaccine from ultra-low temperature central storage to receipt by the end user was tested across NHS Wales as part of a "dummy simulation exercise". This exercise was a follow up arrangement to an initial test on the 12 November, expanding the logistics to include multiple delivery sites and aligning all the necessary consumables required to undertake a vaccination clinic.
