Recorded vaccination status by vaccine for each cohort from January 1, 2006 to December 31, 2015, New Zealand. ‘Out of range’ = MMR vaccine given before 12 months old or possibly indicates a data error (e.g., vaccine recorded as given prior to birth) for the other vaccines.

†Introduced in 2008
Note: ‘Total’ = children in each cohort with an enrolment record or at least one record in the National Immunisation Register. ‘Vaccinated-on time’ = complete and timely vaccination. ‘Vaccinated-delayed’ = vaccinations given > 1 month after the scheduled date for the 6-week, and 3-, 5- and 15-month vaccinations, and > 6 months after for the 4-year vaccinations. In a multi-dose series, it was considered delayed if any one dose was given late. ‘Vaccinated-partial’ = less than the scheduled doses were received based on the child’s age. ‘Unvaccinated’ = no record on the NIR for the particular vaccine or actively declined vaccination. ‘Out of range’ for MMR = vaccines given before 12 months old or possibly indicates a data error (e.g., vaccine recorded as given prior to birth) for the other vaccines.
