Additional Chief Secretary, Health, Rajeev Arora on Thursday said that the State Government is all set to carry out the third round of the Covid-19 sero survey in the State and all the necessary preparations in this regard have already been made.
Arora said that the study will also collect the data to know the vaccination effect and efficacy and will help us in planning and strengthening paediatric services including the establishment and upscaling of intensive care units (PICU). The study is to provide us information regarding susceptible populations and areas in the State, to channelize and prioritize the vaccination drive in these areas, he said.
