Mark Flett is a key part of the vaccination team ST HELENS has one of only three mass vaccination centres in the north west on its doorstep. The Totally Wicked Stadium is actually comprised of two vaccine clinics: the mass vaccination centre for anyone in the north west, located upstairs, and a GP-led clinic downstairs. Supply availability tends to dictate which vaccine patients receive. Downstairs, GPs usually give out the Pfizer vaccine as its fragility means it must be stored in a more specific way than the Oxford-AstraZeneca. But it very much depends on supply, says Jeanette Livings, senior communications and engagement manager at NHS St Helens CCG.
