Vaccinations
Immunisation Schedule
Different vaccines work best when given at certain ages. For example, the measles vaccine is usually not given until the child is at least one year old. It may not work so well if given earlier than the recommended age. Some vaccines such as *DTaP / IPV / Hib need to be given as a series of injections to work best.
- *Diphtheria/Pertussis/Tetanus (DTaP)
- Inactivated Polio (IPV)
- Hameophilus Influenzae type B (HiB)
What Happens If My Child Misses A Shot?
If your child did not get her shots on time, it is not too late.
If your child has gotten some of her shots and then fallen behind schedule, she can catch up without having to start the whole schedule again.
Combination Vaccines
Combination vaccines such as measles, mumps, rubella (MMR) are a few vaccines given together in a single shot. Both doctors and parents like them because it enables a person to receive several vaccines in one go.

Vaccination Checklist ?
Sometimes a child should not be given a particular vaccine or it should be given at a later date. Therefore tell your doctor if your child:
- Is sick today
- Has any allergies e.g. egg allergy
- Has developed a severe reaction after being vaccinated previously
- Has ever had a seizure or any kind of disorder of the nervous system
- Does not seem to be developing normally
- Has a weakened immune system e.g. on steroids or has a cancer
- Has any household contacts with a weakened immune system e.g. on steroids or has a cancer
- Has received any blood transfusion (e.g. immunoglobulins) recently
Is Vaccination Safe?
Vaccination is generally a very safe procedure. Like other medications, they can occasionally cause reactions. Most of these are mild, such as a sore arm or mild fever. Serious reactions are rare but can occasionally happen.
Vaccination with BCG produces a small raised bump 2 weeks later. The raised bump ulcerates within 2 to 4 months, and heals slowly with scarring. For MMR (measles, mumps and rubella) vaccine, fever occurs 6 days or later after vaccination. One can also develop a chicken pox-like rash after being vaccinated against chicken pox.
If there are any serious reactions, see your doctor as soon as possible. Your doctor can discuss the risks before vaccinating your child. Remember that getting the disease is generally much more serious than the side-effects of the vaccine.
Will Vaccines Always Work?
Vaccinations work most of the time, about 90-99% of the children will develop immunity to them. However, occasionally a child may not respond to a vaccine. This is another reason why all children need to be vaccinated. A child who has not responded to a particular vaccine could be infected by a child who is not vaccinated, but not by one who is immune.
