"news out of the UK shows 1 in 10 in hospital with covid have been fully vaccinated"
Well there are statistics and statistics. The UK prioritised vaccinations as in Australia by priority groups. My guess would be some of the hospitalisations may well have nothing to do with covid but more the underlying health condition and they just happen to have covid.
Latest data shows 65-90% reduction in symptomatic disease, 75-95% reduction in hospitilisation, 95-99% reduction in mortality after 2 doses and depending on vaccine type.
