Delhi Chief Minister Arvind Kejriwal on Monday launched a door-to-door survey to vaccinate people above 45-years of age at their polling booths after the number of people to get the jab at vaccination centres plunged. Announcing an ambitious plan, Mr Kejriwal said that if there is no shortage of vaccines, everyone above 45 years of age will be vaccinated in the city within four weeks. There are 57 lakh people in Delhi who are above 45 out of which 27 lakh have received their first jab.
