What does childhood immunisation mean in children?

A vaccine presents the immune system with a safe form or part of a germ, or instructions that help the body recognise it. The child can then build immune memory without having to experience the full infection first. Protection develops over time and may require more than one dose because immunity can change as children grow.

Immunisation helps protect the vaccinated child and can reduce the chance of infections spreading to babies or people whose immune systems need extra protection. Vaccines are selected for a child’s age and health circumstances, so the schedule is personalised when needed.

Keep the child’s vaccination record available and tell the clinician about allergies, previous vaccine reactions, current illness, long-term conditions, or medicines. After vaccination, mild soreness, tiredness, or a temperature can occur as the immune system responds. Offer fluids, allow rest, and follow the clinician’s advice about comfort measures.

If a dose was delayed, contact the child’s clinic to review the record and plan the next dose. Do not restart a schedule without professional advice. More detail is available in Childhood Immunisation.

Seek urgent help if a child has trouble breathing, swelling of the face or throat, becomes unusually floppy or difficult to wake, or develops a rapidly worsening reaction after vaccination. These reactions are uncommon but need prompt assessment.

For a persistent fever, worsening redness or pain at the injection site, or any symptom that concerns you, contact the child’s healthcare professional. Keep the vaccine name and timing available when describing the reaction.

Which vaccines are due now, and when should the next dose be given? Does my child’s health history change the schedule? What reactions should we expect, and which symptoms need urgent help?
