Redness and hard swelling on vaccine sight in right thigh of my baby. Kindly suggest what to do. I started cold compress but it doesn’t seems to heal. Kindly help

A. Thermophob after doing cold compress you can apply you can do it three or four times in the day right after the vaccination when you get your child home do this process this will help in avoiding swelling and if there’s any it will help in settling it down and if the pain is much you can give paracetamol and if needed please consult your doctor
