Ranganath Navalgund, former director of Space Applications Center, Indian Space Research Organisation, has been waiting at Aster CMI hospital in Bengaluru since 10 am for a Covid-19 vaccination. Little did he know that after waiting for over two hours he would be turned away as he had not registered himself on the CoWIN app but had walked in for the jab. “I tried registering on the CoWIN app but I could not select the venue where I wanted to get the vaccination so I chose to walk in,” said a visibly tired sexagenerian. However, once the BBMP officials arrived with the vaccine shots at noon, he was informed that they are not allowing walk-in vaccinations for the first week to avoid overcrowding.
