The third Covid-19 vaccine is being rolled out across Wales from today (Wednesday) with patients in Carmarthenshire becoming thwe first in the UK to receive it.
The Medicines and Healthcare Products Regulatory Agency (MHRA) authorised the Moderna vaccine as safe and effective in January following stringent clinical trials.
Supplies arrived in Wales yesterday (Tuesday 6 April) with 5,000 doses being sent to vaccination centres in the Hywel Dda University Health Board area.
The first doses will be administered at the West Wales General Hospital in Carmarthen today (7 April).
The Moderna vaccine is a two dose vaccine given at an interval of between four and 12 weeks.
Health Minister Vaughan Gething said: "This is another key milestone in our fight against the Covid-19 pandemic. A third vaccine for use in Wales significantly adds to our defences in the face of coronavirus and will help to protect our most vulnerable.
"Every vaccine given to someone in Wales is a small victory against the virus and we would encourage everyone to go for their vaccine when invited.
"I want to thank all those who have been working tirelessly to deliver the vaccine across Wales and help us meet our second milestone of offering a vaccine to all phase one priority groups. I also want to thank the 1.5 million people in Wales that have already come forward for their vaccine and done their bit in this national effort."
