WHEN I went to get my first dose of Covid-19 vaccine on June 1 at the Sunway Pyramid Convention Centre, Selangor, I was surprised at how people were allowed to enter the vaccination centre. Some able-bodied seniors were allowed in with their chaperones all the way through, which led to congestion inside the centre. After two hours, people understandably got impatient and many tried to jump the queue when the officials’ backs were turned. The number of people at vaccination centres needs to be managed to prevent the process from turning into a superspreader event. These are my suggestions:> Do not allow chaperones (some had more than one) to accompany able-bodied and mentally sound senior citizens.
