###Human: What is the reason for cough after vaccination in a newborn? ###Assistant: Hi. I believe this is your first child that is why the query. Coughing has got nothing to do with vaccination. It is normal in children below the age of 6 months to cough or sneeze occasionally. Frankly speaking, it does not require treatment as long as the child is able to feed without any difficulty. However, you can give drops Kofarest (Codeine and Chlorpheniramine) and drops Maxtra (Oxymetazoline) for relief. What you should watch for is lethargy and refusal to feed, breathlessness and cyanosis. These are the warning signs requiring attention. If these warning signs are present then you need to visit the nearest hospital.
