LONDON - Boris Johnson is considering telling over-50s to shield themselves at home if the UK is head by a second wave (Picture: AFP/Reuters) Millions of people over the age of 50 could be asked to stay at home under Boris Johnson’s plan to avoid the ‘nuclear’ option of a second nationwide lockdown. The targeted approach to deal with a potential second wave of coronavirus infections reportedly emerged in a ‘war game’ session with Chancellor Rishi Sunak this week. Under the proposal, people aged between 50 and 70 could be given ‘personalised risk ratings’ – based on factors such as age and health conditions – and asked to shield themselves in the event of an outbreak, the Times reported. During lockdown, more than two million were deemed to be most at risk and asked to shield themselves from the deadly virus at home.(FA)
