Vaccination: Why It Matters So Much
Vaccines let the body practise recognising a disease-causing agent before it actually meets one. Leave your child's specific schedule to a medical facility to advise on.

The immune system learns by remembering. When it meets something that causes disease, the body takes time to recognise it and mount a response — and in that time the illness may already have become severe, especially in young children.
Vaccines shorten that gap. They let the body get to know the cause in advance, so that if it meets the real thing later, the protective response comes faster and stronger.
It protects more than one person
When most of a community is protected, a germ finds it harder to spread. That indirectly shields the people who cannot be vaccinated or who respond poorly: babies who are too young, people with underlying conditions, and people on treatment that weakens the immune system.
That is why vaccination is both a matter for each family and a matter for everyone.
Common reactions
After a vaccination, a child may have a mild fever, be unsettled, have pain or redness and swelling at the injection site, and feed or eat a little less well. These are common reactions and usually settle on their own.
The vaccination centre will ask you to stay and watch your child there for a period of time and then carry on watching at home. Do exactly that, and ask everything you need to before you leave.
Why you should not look up the schedule online yourself
The vaccination schedule depends on age, medical history, current state of health, the doses already given, and which vaccines are available locally. This needs to be assessed in person by a health worker.
Keep the vaccination record safe and bring it every time you go for a vaccination or a check-up. If a dose is missed, do not simply drop it — go to a medical facility to be advised on how to carry on.
When to seek care immediately
After a vaccination, take your child to a medical facility immediately if you see:
- A high fever that is hard to bring down, or a fever that goes on and on
- Lethargy, difficulty waking, seizures
- Difficulty breathing, fast breathing, blue lips, hives spreading quickly, swelling of the lips and eyes
- Constant crying that cannot be soothed
- The injection site badly swollen, with redness spreading, or discharge
- You feel your child is not themselves and cannot explain why
Every question about vaccines deserves to be asked. Ask your doctor or the vaccination staff rather than looking for the answer on social media.
