Nid yw'r cyngor ynglŷn â phobl ifanc 12-15 oed wedi newid, sef y dylid cynnig dau ddos o frechlyn Pfizer i’r rhai rhwng 12 a 15 oed sydd â chyflyrau iechyd sylfaenol penodol sy’n golygu bod risg iddynt gael COVID-19 difrifol, fel y nodir yn y Llyfr Gwyrdd, gyda chyfnod o wyth wythnos rhwng dosau.
The advice on 12-15 year olds has not changed and remains that persons aged 12-15 years with specific underlying health conditions that put them at risk of severe COVID-19, as set out in the Green Book, should be offered two doses of Pfizer vaccine with an interval of eight weeks between doses.
