Hello, My 3 year old daughter frequently falls sick with a cold and cough nowadays. She goes to playschool and she is very active kid. During holidays, she will be fine but when she goes to school l, she falls sick. She also complains about tiredness. I don't understand if it's because of Bangalore humid weather or if she is catching it from school. Is there any vaccine that we need to give her to protect against frequent viral cold and cough.
