13 January 2021 • 12:01am Mavis, 87, is pushed by her daughter out of the Covid-19 vaccination centre at ExCel London, home to the London Nightingale Hospital Credit: DANIEL LEAL-OLIVAS/AFP SIR – My 90-year-old aunt experienced total chaos on Monday morning when attending her appointment for a Covid-19 vaccination at the new Epsom Downs Racecourse vaccination hub. Her appointment was for 10.05am. On arrival, she joined a queue of cars, where she remained for four hours, waiting to be processed. She was then told she could leave the car and join a walking queue in the freezing cold, which snaked around the buildings. Five hours after arriving, my aunt gave up, along with many other elderly people in the queue, and returned home without being vaccinated.
