What are the common diseases in newborns and their prevention, does there any course we have to adopt for vaccination and other precautionary actions to prevent them from any viral disease?

Make your GP and your local nurse your best friends. They usually have pamphlets stating what to vaccinate and at what age.

Yes work with your child's pediatrician. In our state they have well baby care appointments to help monitor their health and grought and for immunizations.

I am not sure where you people are in the world but in the U.K they have a call back system for immunising your child and you have to opt out of the system if you do not want your child to be immunised. Which I think is better than opting into the imms programme.
