Coronavirus Northern Ireland: We may never return to normality despite success of vaccine, warns Professor Young

After almost a year living under the shadow of a pandemic, the approval of two Covid-19 vaccines finally brought some hope to a world weary of coronavirus. There isn't a part of our lives that hasn't been affected by Covid-19 - schools are closed for the third time, life-saving operations are being cancelled, the business community is on its knees, even the simple act of giving a loved one a hug is no longer acceptable. Throughout everything that Covid-19 has thrown at us, we've held on to the day when a vaccine would be rolled out and lives could finally return to normal.
