JCVI is understood to have concerns about the affect of the jab on other childhood inoculations
Confusion is growing over whether all children aged 12 and over will soon be offered a Covid jab as schools in England prepare to return next week, with the NHS gearing up for vaccinations but government scientists warning of potential complications.
Amid uncertainty over the parallel issue of who may be given a third, “booster”, jab the Joint Committee on Vaccination and Immunisation (JCVI) is understood to have concerns on issues including knock-on effects on other childhood vaccinations, and the logistics of a mass programme for 12- to 15-year-olds.
