Corona vaccination has started in Chhattisgarh. In the first phase, 2 lakh 67 thousand health care workers are to be vaccinated. But doctors are still asking to take the same precautions like putting on masks, keeping a safe distance, avoiding going into the crowd. Dr. OP Sundarani, an expert physician at the Medical College Hospital (Mekahara), believes that the corona infection is not completely eradicated. There are still cases of Kovid coming and death. Therefore, whether or not they have the corona vaccine or not, it is extremely important to wear the mask properly. He said that within two weeks of taking the second dose, a protective immunity level of antibodies usually develops. That is why it will be necessary to behave in a cavidic manner even after applying the vaccine, thereby reducing the risk of corona.
