UK clinical trials have played a critical role in the development of effective vaccines against COVID\-19 and I am extremely grateful to the many people from Wales who took part in a vaccine trial. Just under 1,400 people in Wales selflessly stepped up when we needed them. It is a truly remarkable act of generosity and kindness to their fellow human beings. 


Trial participants were rightly promised they would not be disadvantaged for taking part in approved COVID\-19 vaccine trials in the UK. However, I know some trial participants have had difficulty accessing a booster vaccination or COVID international Travel Pass. This is because not all trial participants received a vaccine approved by the Medicines and Healthcare Regulatory Authority (MHRA). 


Today, the Chief Medical Officer for Wales has written to trial investigators and NHS medical directors across Wales to set out the process for addressing this issue as quickly as possible. From tomorrow, trial participants will start to receive letters explaining how, if they meet the eligibility criteria, they will be offered their booster, or if they require one, how to get a further primary course of vaccine to enable them to get a COVID Travel Pass. This is in line with principles endorsed by the Joint Committee on Vaccination and Immunisation (JCVI) for trial participants.


I am determined to resolve this issue for everyone affected in Wales in recognition of their contribution that has benefited us all.

Mae treialon clinigol yn y Deyrnas Unedig wedi bod yn hollbwysig yn y gwaith o ddatblygu brechlynnau effeithiol yn erbyn COVID\-19 ac rwy'n hynod ddiolchgar i'r nifer fawr o bobl o Gymru a gymerodd ran mewn treialon. Fe wnaeth bron i 1,400 o bobl yng Nghymru gamu i’r adwy pan oedd eu hangen arnom. Dyna weithred ryfeddol o hael a charedig ar ran pobl eraill.    


 


Yn hollol briodol, addawyd i’r rhai oedd yn cymryd rhan na fyddent o dan anfantais o gymryd rhan mewn treialon ar gyfer brechlyn COVID\-19 a oedd wedi’u cymeradwyo yn y DU. Serch hynny, rwy’n gwybod bod rhai ohonynt wedi cael anhawster i gael brechiad atgyfnerthu neu Bàs Teithio Rhyngwladol COVID. Y rheswm am hyn yw nad oedd pob un a gymerodd ran yn y treialon wedi cael brechlyn sydd wedi’i  gymeradwyo gan yr Awdurdod Rheoleiddio Meddyginiaethau a Gofal Iechyd (MHRA).


Heddiw, mae Prif Swyddog Meddygol Cymru wedi ysgrifennu at ymchwilwyr y treialon a chyfarwyddwyr meddygol y GIG trwy Gymru i amlinellu’r broses ar gyfer ymdrin â'r mater hwn cyn gynted â phosibl. O yfory ymlaen, bydd y rhai sydd wedi cymryd rhan mewn treialon yn dechrau cael llythyrau yn esbonio sut y gallant gael eu dos atgyfnerthu, os ydynt yn bodloni'r meini prawf cymhwysedd. Byddant yn cael gwybod hefyd sut i gael cwrs arall o’r brechlyn i’w galluogi i gael Pàs Teithio COVID, os oes angen un arnynt. Mae hyn yn cyd\-fynd ag egwyddorion a gymeradwywyd gan y Cyd\-bwyllgor ar Imiwneiddio a Brechu (JCVI) ar gyfer y rhai sydd wedi cymryd rhan mewn treialon.


Rwy’n benderfynol o ddatrys y mater hwn i bawb yng Nghymru y mae hyn yn effeithio arnynt, er mwyn cydnabod eu cyfraniad sydd wedi bod o fudd i bob un ohonom.
