I can get a flu jab from all good pharmacies*, most crap ones and, in all likelihood, branches of Nobby & Dick's Auto Salvage (Finchley), but a Coronalurgi booster requires travel to the far-flung reaches of E17, to regions so distant they are practically in Leyton. Either that or the NHS website is suffering from geographical bias. “Ewwwwwww, he lives north of Forest Road! Let him suffer!”
Bah!
