Non-vulnerable people perhaps don’t understand why the government advice to shielders is so frightening. I think I can give a flavour though: Shielding is to be eased on the 1st April. Nobody in the “extremely clinically vulnerable” group – whom the virus would likely kill – will have had their second jab by this point. Infection levels are still around 5,000-6,000 new cases per day, nationwide. This is not low.
