O ran plant a phobl ifanc 12-15 oed nad oes ganddynt gyflyrau iechyd sy’n bodoli eisoes, dywedodd y Cyd-bwyllgor ar Imiwneiddio a Brechu yn ddiweddar fod manteision brechu ychydig yn fwy na’r niwed posibl y gwyddom amdano. Ond o safbwynt manteision iechyd i unigolion, nid oeddent o’r farn bod y manteision yn ddigon iddynt argymell rhaglen frechu gyffredinol i blant a phobl ifanc 12-15 oed. Roeddent hefyd yn cynghori, os y byddai Gweinidogion yn cydnabod bod materion ehangach i’w hystyried, materion nad yw’r Cyd-bwyllgor yn gyfrifol am eu gwerthuso o fewn ei gylch gwaith, er enghraifft, materion addysgol ac iechyd meddwl fod y pedwar Prif Swyddog Meddygol mewn sefyllfa well i roi cyngor ar hyn. Y materion ehangach hynny yw’r hyn y mae’r Prif Swyddogion Meddygol wedi’u hystyried yn fanwl, gan gynnwys mewnbwn clinigol ac iechyd y cyhoedd annibynnol sydd ar lefel uwch o bob rhan o’r DU.
Recently, the Joint Committee for Vaccination and Immunisation (JCVI) advised that for children and young people aged 12-15 who do not have underlying health conditions, the individual health benefits from vaccination are slightly greater than the potential known harms, but that the margin of benefit, is considered too small for them to recommend a universal programme of vaccination. They further advised that, should Ministers agree there are wider issues to consider which were outside the remit of JCVI to evaluate, for example, education and mental health issues, that the 4 CMOs were best placed to advise in this respect. These wider issues are what the CMOs have considered in detail, further informed by independent senior clinical and public health input from across the UK.
