Vaccines are used to prevent serious infections and reduce complications. This page answers common parent questions. It is not a full vaccine schedule, catch-up calculator, consent form, emergency guide, or substitute for a visit with your paediatrician using current guidance.

What vaccines do

Vaccines train the immune system to recognise specific infections and respond more effectively if the child is exposed later. They do not promise complete protection, but they reduce the risk of many serious infections, complications, hospitalisation, and spread.

Why vaccination matters

Vaccination protects the child and also helps reduce spread in the community. This matters for newborn babies, pregnant women, elderly relatives, and people with weak immune systems who may be harmed more severely by infections.

Vaccine planning may include routine government vaccines and additional vaccines advised by the paediatrician. Timing can vary based on age, previous doses, health conditions, outbreak or travel risk, vaccine availability, and current guidance.

Common parent questions

Should my child follow one fixed chart? Use the current schedule recommended for your child by the vaccinating doctor. This FAQ does not publish a full schedule because guidance changes and catch-up decisions must be individualized.
  • Can multiple vaccines be given at one visit? Multiple vaccines may be given at the same visit when recommended by current guidance and the vaccinating doctor.
  • Are combination vaccines allowed? Combination vaccines can reduce the number of injections when appropriate and recommended for the child.
  • Should vaccines be skipped because of fear of fever? Do not skip vaccines only because fever may occur. Mild fever can be an expected short-term reaction after some vaccines.
  • Do vaccines have side effects? Like any medicine, vaccines can have side effects. Most are mild and short-lived, but serious reactions need urgent care.

Missed or delayed vaccines

If a vaccine dose is missed, do not guess the next dose at home and do not copy another child's plan. Contact your paediatrician, bring the written or digital vaccine record, and ask for a catch-up plan based on current guidance.

  • Bring all previous vaccine records, even if incomplete.
  • Tell the doctor about previous reactions, chronic illness, immune problems, medicines, travel, and outbreaks in the community.
  • This FAQ does not provide catch-up intervals or a personalised catch-up schedule.

Vaccination during mild illness

A minor cough, cold, mild diarrhoea, or low-grade fever may not always require postponement if the child is otherwise well, but the vaccinating doctor should assess the child.

Vaccination may be delayed when a child is moderately or severely unwell, has high fever, has a serious allergic reaction history, or has a condition that affects vaccine eligibility. Ask the vaccinating doctor rather than deciding at home.

Common expected side effects

  • Mild fever, soreness, mild swelling, redness, tiredness, reduced appetite, or temporary fussiness can happen after some vaccines.
  • These expected symptoms usually settle with time and simple comfort care.
  • For mild expected symptoms, follow the advice given by the vaccinating doctor.
  • This page does not provide exact paracetamol or ibuprofen amounts.

When to call the doctor urgently after vaccination

Seek urgent medical care immediately for severe allergy-like symptoms or breathing difficulty. Watch for breathing difficulty, swelling of the face, lips, or tongue, widespread hives, collapse, seizure, or a child who becomes very drowsy or difficult to wake.
  • Persistent inconsolable crying.
  • Very high or persistent fever.
  • Severe swelling, redness, pus, or worsening pain at the injection site.
  • Any reaction that makes the parent very worried.

Vaccine record and follow-up tips

  • Keep a written or digital vaccination record and take it to every vaccine visit.
  • Ask the clinic to write the vaccine name, date, batch details if recorded locally, and next due date.
  • Keep photos or digital copies of the vaccine card in case the paper card is misplaced.
  • Before travel, school admission, outbreak exposure, or a missed dose, review the record with your paediatrician.

Important safety notes

  • Do not use this FAQ as a complete schedule or catch-up calculator.
  • Do not skip vaccines because of fear of fever. Discuss expected reactions and fever care with the vaccinating doctor.
  • Tell the doctor about previous serious allergic reactions, immune problems, cancer treatment, long-term steroid or immunosuppressive medicines, pregnancy in adolescents, or severe illness on the day of vaccination.
  • Vaccine choices and timing may vary for premature babies, children with chronic illness, outbreak exposure, travel, or incomplete records.
