Tobacco promotion increases the likelihood that adolescents will start smoking. Much of the tobacco industry's promotional budget is spent on point of sale (PoS) promotion in many jurisdictions. Consequently, tobacco is an eye-catching feature at the PoS in many places. We reviewed the evidence that PoS tobacco promotion influences key smoking-related behaviors and beliefs, increases susceptibility to smoking in youth, undermines smokers' quit attempts, and promotes relapse among ex-smokers. We found 12 peer-reviewed studies, 10 of which were focused on children. Seven of 8 observational studies found statistically significant associations between exposure to tobacco promotion at the PoS and smoking initiation or susceptibility to smoking. Two experimental studies of children found statistically significant associations between exposure to PoS tobacco promotions and beliefs about ease of getting tobacco and smoking prevalence among their peers. An experimental study with adults found that a picture of collected tobacco pack elicited cravings for cigarettes among smokers. A cross-sectional study found that 25% of adult smokers reported impulse purchasing and a third of recent ex-smokers reported urges to start smoking after seeing tobacco displayed. More prospective studies are needed to clarify the temporal relationship between exposure to PoS tobacco and outcome. However, given the addictiveness of tobacco, the severity of the health hazards posed by smoking, the evidence that tobacco promotion encourages children to start smoking, and the consistency of the evidence that PoS promotion influences children's smoking, we believe that ample justification exists for banning PoS advertising and displays of smoked tobacco products.

Gonorrhea is a major global public health problem with emergence of multiple drug-resistant strains with no effective vaccine. This retrospective cohort study aimed to estimate the effectiveness of the New Zealand meningococcal B vaccine against gonorrhea-associated hospitalization. The cohort consisted of individuals born from 1984 to 1999 residing in New Zealand. Therefore, it was eligible for meningococcal B vaccination from 2004 to 2008. Administrative datasets of demographics, customs, hospitalization, education, income tax, and immunization were linked using the national Integrated Data Infrastructure. The primary outcome was hospitalization with a primary diagnosis of gonorrhea. Cox’s proportional hazards models were applied with a Firth correction for rare outcomes to generate estimates of hazard ratios. Vaccine effectiveness estimates were calculated as 1-Hazard Ratio expressed as a percentage. There were 1,143,897 eligible cohort members with 135 missing information on gender, 16,245 missing ethnicity, and 197,502 missing deprivation. Therefore, only 935,496 cohort members were included in the analysis. After adjustment for gender, ethnicity, and deprivation, vaccine effectiveness (MeNZB™) against hospitalization caused by gonorrhea was estimated to be 24% (95% CI 1–42%). In conclusion, the data suggests vaccination with MeNZB™ significantly reduced the rate of hospitalization from gonorrhea. This supports prior research indicating possible cross protection of this vaccine against gonorrhea acquisition and disease in the outpatient setting.

Objective: To examine the association between exposure to tobacco displays at the point of sale and teenage smoking and susceptibility to the uptake of smoking. Design: The sample comprised a national cross-section of 14–15 year olds with two measures of exposure to tobacco displays at the point of sale and three outcome measures. The outcome measures were susceptibility to smoking initiation, experimenting with smoking or current smoking. Results: Compared with visiting stores less often than weekly, a greater frequency of store visits was related to increased odds of being susceptible to smoking (daily visits, adjusted OR 1.8, 95% CI 1.6 to 2.2) and experimenting with smoking (daily visits, adjusted OR 2.7, 95% CI 2.4 to 3.1). The likelihood of being a current smoker increased with a greater frequency of store visits among students of medium and high socioeconomic status, but not among those of low socioeconomic status. Conclusion: Although these findings are cross-sectional in nature, they are consistent with the notion that greater exposure to tobacco displays at the point of sale increases youth smoking, and suggest display bans are needed.

Objectives Actively recruit and intensively follow pregnant women receiving a dose of acellular pertussis vaccine for 4 weeks after vaccination. Design and settings A prospective observational study conducted in 2 New Zealand regions. Participants Women in their 28th–38th week of pregnancy, recruited from primary care and antenatal clinics at the time of Tdap administration. Telephone interviews were conducted at 48 h and 4 weeks postvaccination. Main outcomes measures Outcomes were injection site reactions, systemic symptoms and serious adverse events (SAEs). Where available, data have been classified and reported according to Brighton Collaboration definitions. Results 793 women participated with 27.9% receiving trivalent inactivated influenza vaccine concomitantly. 79% of participants reported mild or moderate pain and 2.6% severe pain. Any swelling was reported by 7.6%, induration by 12.0% (collected from 1 site only, n=326), and erythema by 5.8% of participants. Fever was reported by 17 (2.1%) participants, 14 of these occurred within 24 h. Headache, dizziness, nausea, myalgia or arthralgia was reported by <4% of participants, respectively, and fatigue by 8.4%. During the study period, there were 115 adverse events in 113 participants, most of which were minor. At the end of the reporting period, 31 events were classified as serious (eg, obstetric bleeding, hypertension, infection, tachycardia, preterm labour, exacerbation of pre-existing condition and pre-eclampsia). All had variable onset time from vaccination. There were two perinatal deaths. Clinician assessment of all SAEs found none likely to be vaccine related. Conclusions Vaccination with Tdap in pregnant women was well tolerated with no SAE likely to be caused by the vaccine. Trial registration number ACTRN12613001045707.

Migrants may experience immunisation inequities compared with the host population related to barriers with accessing immunisations in their home countries, while migrating and/or post-arrival. This retrospective cohort study explored vaccination rates among migrant and non-migrant children in New Zealand (NZ). Linked de-identified data from various government sources from 1 January 2006 to 31 December 2015 were analysed using Statistic NZ’s Integrated Data Infrastructure. Vaccination rates were compared between three cohorts of children aged up to 5 years: foreign-born children who migrated to NZ; children born in NZ of migrant mothers; and a comparator group of children born in NZ to non-migrant mothers. Less than half of foreign-born children (46%) had a record in the NZ National Immunisation Register compared with 95% and 96% among migrant and non-migrant NZ-born children, respectively. Foreign-born migrant children had lower age-appropriate reported vaccination rates by vaccine of interest, ethnicity and visa category compared with NZ-born children. Migrant children from Pacific ethnicities had lower reported coverage than other ethnicities. High rates of not age-appropriately vaccinated were noted among foreign-born children on refugee, Pacific and humanitarian visa schemes. This study highlights possible shortfalls around immunisation data, particularly about recording vaccinations given overseas for foreign-born children, and potential challenges around engagement with immunisation services for migrant children. However, results highlight the successful engagement of quota refugee children as part of NZ’s refugee orientation programme. It is important to monitor vaccination coverage by migrant and refugee background to inform improvements to policy and practice for wider population health benefits.
