Ers diwedd mis Mawrth, mae pobl 75 oed a hŷn, preswylwyr mewn cartrefi gofal, ac unrhyw un sy’n 12 oed neu hŷn ac sydd â system imiwnedd gwan wedi gallu cael pigiad atgyfnerthu’r gwanwyn i wella eu lefel o amddiffyniad yn erbyn COVID-19.
Since late March, people aged 75 and over, care home residents, and anyone aged 12 or over who is immunosuppressed have been able to get their spring booster to increase their level of protection against COVID-19.
