Hyd yma, cyflogwyr unigol oedd yn gyfrifol am gynnig brechiad rhag y ffliw i staff gofal cymdeithasol. Er gwaethaf lefelau uchel o frechu ymysg preswylwyr, gall y ffliw ledaenu'n rhwydd o fewn cartrefi gofal, a chael ei basio i breswylwyr gan staff â symptomau ysgafn iawn, os o gwbl. Mae hynny'n digwydd, i raddau, gan nad yw imiwnedd pobl yn ymateb mor dda i'r brechiad wrth heneiddio, ac yn golygu bod brechu staff sy'n gofalu am bobl hŷn a bregus yn bwysicach fyth.
Until now, responsibility for offering flu vaccine to social care staff has rested with individual employers. Despite having high flu vaccination rates in residents, flu can spread easily within care homes and can be passed from staff to residents when the staff member has mild or even no symptoms. This is partly because, as people age, they do not produce as good an immune response to vaccination. This makes vaccination of staff caring for frail, older people even more important.
