Rydym yn parhau i annog y rhieni hynny sydd heb roi caniatâd i’w plant gael eu himiwneiddio fynd ati i ofyn am y brechlyn. Os ydynt yn dymuno, gall plant hŷn a phobl ifanc roi caniatâd eu hunain i gael eu brechu. Yn ogystal â’r effeithiau amlwg ar eu hiechyd nhw eu hunain, mae’r unigolion sydd heb eu brechu yn achosi mwy o risg i iechyd pobl eraill. Yn fwy cyffredinol, pan geir achosion y gellid bod wedi eu hosgoi, mae hynny’n golygu bod rhaid tynnu gwasanaethau oddi wrth ddyletswyddau pwysig eraill. Mae’r dyletswyddau hynny wedyn yn gorfod aros tra bydd ymateb cyflym yn cael ei drefnu.
We  continue to urge those parents who have still not consented to having their children immunised to come forward and seek vaccination. Older children and young people can consent to the vaccination themselves if they wish.  Quite apart from the obvious health effect to the individuals themselves, those without vaccination pose a greater threat to the health of others. More generally when avoidable outbreaks occur, services have to be diverted from other important duties which then have to wait so that a rapid response can be put in place.
