In mid march I was covid positive. In april first week I recovered with zero score. On 8 september I took covishield first dose. After dose 2 days there were mild side effects. During this my both kids were suffering from runny nose, cough and cold. From yesterday I am feeling cold symptoms body ache, mucus in nose, nose block etc. Feeling like ill mild cough is there. What is reason behind this its due to vaccine or I got kids infection or something else. Pls. Reply. Regards.
