Smoking cessation

Changes to smoking habits and addiction following tobacco excise tax increases: a comparison of Māori, Pacific and New Zealand European smokers
The objective of this study, published in the Australian and New Zealand Journal of Public Health, was to compare changes in smoking habit and psychological addiction in Māori/Pacific and NZ European smokers in response to two annual excise tax increases from 2012 to 2014.

Vaccination

Age-specific effectiveness following each dose of acellular pertussis vaccine among infants and children in New Zealand
Though it is believed the switch from whole cell to acellular pertussis vaccine has contributed to the resurgence of pertussis disease, few studies have evaluated vaccine effectiveness (VE) and duration of protection provided by an acellular vaccine schedule including three primary doses but no toddler-age dose. This study, published in Vaccine, assessed this schedule in New Zealand (NZ), a setting with historically high rates of pertussis disease, and low but recently improved immunisation coverage. We further evaluated protection following the preschool-age booster dose.
