By and large vaccinations are safe. But it always pays to do the following before you receive vaccination:
HT ImageBe aware. Know the details about the vaccination you or your child is about to receive.
Go to an authorised centre for vaccination. Be sure of their storage and handling facilities.
Use disposable syringes.
Tell your doctor if there is a family history of allergies, especially to eggs, feathers etc.
If you are pregnant, be sure to tell your doctor that, before you take any vaccination.
Monitor post vaccination reactions closely.
Maintain a vaccination record.
