Childhood vaccinations: what the schedule protects against
Immunisation works by teaching the immune system to recognise a disease safely, so the body can respond quickly if it meets the real thing. It is among the most effective preventive measures in medicine.
How the schedule is structured
Kenya’s national immunisation programme provides vaccines free at public health facilities. Doses begin at birth and continue through the first two years, with protection against tuberculosis, polio, diphtheria, tetanus, whooping cough, hepatitis B, Haemophilus influenzae type b, pneumococcal disease, rotavirus, measles and rubella, among others. Additional vaccines, including HPV for older girls, are offered at set ages.
Exact timings are set nationally and are occasionally updated, so follow the dates written on your child’s card and confirm with your health facility rather than relying on a schedule you read elsewhere.
Why the timing matters
Doses are spaced to build immunity when children are most vulnerable. Giving them early does not help, and delaying leaves a gap in protection. Several vaccines need more than one dose to work properly, which is why finishing a course matters.
What to expect afterwards
Common and expected reactions include mild fever, irritability, and soreness, redness or a small lump at the injection site. These usually settle within a day or two. Offer extra fluids and feeds, and paracetamol if your child is uncomfortable, dosed by weight.
Contact a clinician promptly for a high fever that persists, a seizure, difficulty breathing, swelling of the face or mouth, or a child who is unusually drowsy or unwell. Serious reactions are rare, but they should always be reported.
If you have missed doses
Children who have fallen behind can usually catch up. There is no need to restart a course from the beginning in most cases. Take the child’s card to the nearest facility and ask for a catch-up plan.
Keep the card safe
The immunisation card is an official record needed for school entry and useful at every medical visit. Photograph it and keep a copy somewhere separate, in case the original is lost or damaged.
Common worries
Parents often ask whether a child with a mild cold can be vaccinated. Usually yes: a minor illness without high fever is not a reason to delay. Ask about any other condition, allergy or medicine before the visit. If you are unsure about anything you have read online, raise it with a clinician who can address the specific concern rather than leaving it unanswered.
