O ran y pigiadau atgyfnerthu, mae’r JCVI wedi ystyried a ddylid rhoi pigiadau atgyfnerthu i grwpiau blaenoriaeth pellach sydd o dan 50 oed ac ddim yn grŵp ‘risg uwch’. Yn seiliedig ar y dystiolaeth sydd ar gael ar hyn o bryd, mae’r Pwyllgor wedi argymell y dylid cynnig pigiad atgyfnerthu i’r rheini sy’n 40-49 oed, os oes 6 mis wedi pasio ers eu hail ddos.
Turning to the booster, the JCVI has considered if the roll-out should be extended to include further cohorts who are under 50 and not in an ‘at-risk’ group. Based on the current available evidence, the Committee has recommended that a COVID-19 booster should be offered to those aged 40-49 years old, at 6 months or more following their second dose.
