The current definition of fully immunised for measuring coverage rates includes vaccination against: hepatitis B, diphtheria, tetanus, whooping cough, Haemophilus influenzae type b, polio, measles, mumps, rubella, pneumococcal disease, varicella and meningococcal C. For each age it is assumed that earlier vaccinations in the series have been received.

  • If the area had between 1 and 5 children not fully immunised, the result is published while additional values are suppressed and reported as NP
  • If the area had an eligible population of 26–100 registered children (denominator), the result is marked as interpret with caution (#).
