Wythnos diwethaf, dechreuodd pob bwrdd iechyd yng Nghymru ddarparu brechlynnau i staff cartrefi gofal, pobl dros 80 mlwydd oed a gweithwyr iechyd a gofal cymdeithasol rheng flaen sy’n wynebu’r risg fwyaf. Ddiwrnodau yn unig ar ôl i’r Asiantaeth Rheoleiddio Meddyginiaethau a Chynhyrchion Gofal Iechyd (MHRA) gymeradwyo’r brechlyn COVID-19 cyntaf i’w ddefnyddio yn y Deyrnas Unedig, aeth GIG Cymru ati’n gyflym i symud o’r cam cynllunio i’r cam gweithredu, ac o fewn 48 awr roedd wedi darparu dros 4,000 dos o’r brechlyn. Erbyn diwedd yr wythnos gyntaf, roedd hyn wedi cynyddu i dros 6,000 o bobl a oedd wedi cael y dos cyntaf o’r brechlyn, sy’n dipyn o gamp.
Last week all health boards in Wales started administering vaccines to care home staff, those over 80 years and frontline health and social care workers most at risk.  Just days after the Medicines and Healthcare Products Regulatory Agency (MHRA) approved the first Covid-19 vaccine for use in the UK, NHS Wales moved swiftly from planning to mobilisation and had administered over 4,000 doses of the vaccine within 48 hours. By the end of the first week, this had risen to more than 6,000 people receiving the first dose of the vaccine, which is a huge achievement.
