Heddiw,mae'r Cyd-bwyllgor ar Frechu ac Imiwneiddio (JCVI) wedi dweud y dylidcynnig trydydd dos o frechlyn COVID-19 cynradd i unigolion, 12 oed neu hŷn, a oedd yn imiwnoataliedig iawn ar adeg ei dos cyntaf neu ail o’r brechlyn, neu’r ddau. Y rheswm dros hyn yw na fydd rhai unigolion sy’n ddifrifol imiwnoataliedig oherwydd cyflyrau iechyd isorweddol neu triniaethau meddygol penodol yn cyrraedd imiwnedd llawn o ganlyniad i’r ddwy frechiad gyntaf o’r brechlyn COVID-19.  Mae angen amddiffyniad ychwanegol ar yr unigolion bregus hyn ac rwy'n croesawu'r cyngor hwn.
Today, theJoint Committee on Vaccination and Immunisation (JCVI) have advisedthat a third COVID-19 vaccine primary dose be offered to individuals, aged 12 years and over, who were severely immunosuppressed at the time of either, or both, of their first two vaccine doses. This is because some individuals who are severely immunosuppressed due to underlying health conditions or certain medical treatments may not produce a full immune response to COVID-19 vaccination.  These individuals need additional protection and I welcome this advice.
