What are Vaccines?
Vaccinations are given to create immunity for fighting severe diseases that can leave babies suffering with physical deformities, various long term side effects, or in worse cases can kill your baby. These illnesses can range from simple illnesses like chicken-pox or serious cases like meningitis, or polio.
When should they be given to your baby?
It is important to note that vaccinations are done according to a strictly monitored schedule, specially when it comes to babies. You will receive a vaccination card with a schedule listed on it, either from the public or private sector hospital. You will need to keep this record with you when ever you are going to meet the doctor. This is to make sure the correct dosages of each vaccine are given, and that they are given at the right time. If you have not received this from your hospital that your baby was delivered you will need to get this from your closest general hospital.
