Mae brechiadau ar gyfer y coronafeirws yn effeithiol iawn. Amcangyfrifir, ar ôl i unigolyn gael ail ddos, y bydd ei lefel amddiffyniad rhag cael ei dderbyn i’r ysbyty yn tua 95%. Bydd unigolion hefyd yn cael eu hamddiffyn rhag cymhlethdodau difrifol os byddan nhw’n cael eu brechu rhag y ffliw. Os ydyn nhw’n gymwys i gael brechiad atgyfnerthu COVID-19 neu beidio, rydw i’n annog pob unigolyn sy'n gymwys i gael ei frechu rhag y ffliw.
“Vaccinations for coronavirus are highly effective and protection against hospitalisation is estimated at around 95 per cent after the second dose. The flu vaccine will also protect people from serious complications and I encourage anyone who is eligible to get their flu vaccine regardless of their eligibility for a COVID-19 booster vaccine.
