Do not panic and do not guess.
Most missed vaccine situations can be reviewed and corrected safely, but catch-up planning should be individualized using current guidance and the child's written records.
What does missed or delayed vaccine mean?
A missed vaccine means the child is behind the advised schedule. In many situations, vaccination can continue with a catch-up plan rather than restarting the whole series. The exact plan depends on age, previous records, vaccine type, medical history, travel, outbreak exposure, and risk factors.
When this guide applies
- A vaccine date was missed because of fever, travel, exams, family events, or vaccine unavailability.
- The vaccine record is incomplete or uncertain.
- A child has moved from one city or country to another and schedules differ.
- Parents are unsure whether a vaccine is still useful after delay.
What to do next
- Bring all available vaccine cards, hospital records, school records, discharge summaries, and prior prescriptions to the clinic.
- Ask for a written catch-up plan after record review.
- Avoid taking multiple duplicate vaccines without review.
- For travel, bite wounds, outbreak exposure, or known infectious contact, discuss timing promptly with a doctor.
When to seek prompt medical advice
Seek prompt advice if any of these apply:
- No written vaccine record in an immunocompromised child or child with chronic disease.
- Recent contact with measles, chickenpox, rabies exposure, tetanus-prone injury, or an outbreak setting.
- Infant with no documented primary vaccines.
- Any confusion after a bite, wound, travel exposure, or known infectious contact.
Important facts for parents
- A mild common cold is not always a reason to postpone vaccination, but the vaccinating doctor should decide.
- Catch-up planning should not be done from memory alone when records may exist.
- This guide does not provide a personalized catch-up schedule.
- Use current applicable guidance and your paediatrician's advice.
