Thank you for that response. You'll be aware that older people and other vulnerable groups are also encouraged to undertake the offer of a flu vaccine each winter. There's been considerable concern in north Wales about a shortage of the vaccine across the region, including in my own constituency of Clwyd West. Do you accept that that shortage could potentially put the lives of vulnerable people at risk? And what are you doing to drive up the vaccination rates amongst front-line NHS workers, where there are—a significant proportion of whom do not have these jabs every year and could be putting patients at risk?
