Walk-in COVID-19 vaccination invite extended to those turning 18 before 31 October 2021

Hywel Dda University Health Board (UHB) is in the process of identifying residents who will turn 18 years old on or before 31 October 2021 to invite them to receive their COVID-19 vaccine at a mass vaccination centre.   

However, to avoid any delay, the health board is encouraging all those nearly 18 years old living in Carmarthenshire, Ceredigion or Pembrokeshire to attend a walk-in clinic at one of its mass vaccination centres.  

Please note the Pfizer-BioNTech vaccine is the only vaccine that can be given to those under 18 and is currently available at all Hywel Dda mass vaccination centres except Cardigan and the drive-through showground in Carmarthen.  

Cardigan’s mass vaccination centre will move from its current location to Yr Hen Ysgol Trewen, located at Cwm Cou (SA38 9PE) week beginning 26 July and the health board’s vaccination team is working on the ability to provide a supply of Pfizer for the south of Ceredigion county when the centre reopens in its new location. 

In the meantime, please come along and visit our other centres across the regions to get your vaccine.

There is no need to contact the health board before attending a walk-in clinic but if you wish to schedule an appointment you can do so by contacting our booking team on 0300 303 8322 or by emailing
