Background: Vaccination in pregnancy against influenza and pertussis protects the pregnant woman/person and their infant against severe disease. Aotearoa New Zealand has a lower uptake of vaccination in pregnancy than some other countries, despite this immunisation being publicly funded. Coverage is also inequitable, with Māori, Pacific people, and people from high deprivation areas less likely to be vaccinated. Many barriers exist to vaccinations in pregnancy, e.g., access barriers and lack of knowledge about vaccination. Discussions about recommended vaccines with healthcare professionals, particularly midwives, may have a positive impact on vaccine decision-making. Aim: This study aimed to investigate midwives' perceptions of enablers and barriers with discussions about vaccinations in pregnancy, barriers to vaccination in pregnancy, and influences on vaccine decision-making in pregnancy. The study also aimed to gather midwives' insights into what might improve vaccination uptake. Method: A structured questionnaire was developed containing a mix of closed and open-ended questions. The questionnaire was sent out to 3002 midwives registered in Aotearoa New Zealand in October 2021, using REDCap electronic data capture tools. Simple descriptive statistics were undertaken on the quantitative data. The answers to the open-ended questions were analysed using a direct, qualitative content analysis approach. Findings: Fifty-one midwives' responses were included in the analysis (1.8% response rate). Almost all reported sufficient knowledge of vaccinations in pregnancy but had varying levels of confidence when discussing them. The most common enablers to conversations were good relationships, easy communication, and having the time and resources available. Respondents perceived that barriers to conversations were negative preconceptions, communication difficulties and lack of time. Lack of awareness, cost to access services and competing priorities for time were also thought to reduce the likelihood of vaccination in pregnancy. To improve vaccine uptake, respondents identified the need for accessible and suitable vaccination venues, appropriate information and the support of all healthcare professionals involved in maternal healthcare. Conclusion: Midwives surveyed understand the importance of vaccination in pregnancy but there may be lack of confidence, time or resources to effectively engage in discussions. A trusting relationship is important but this can be affected by disengagement or late presentation to healthcare services. Resources to counter pre-existing negative ideas and support communication would help midwives to provide useful information about vaccination. Furthermore, respect and cultural understanding of hapū Māori and their needs will positively support their ability to make informed decisions. [ABSTRACT FROM AUTHOR]

This paper describes issues, strengths and challenges experienced by elderly Māori accessing influenza vaccination, during the first Level 4 COVID-19 lockdown in 2020. We also obtained views about the introduction of COVID-19 vaccines, and the social restrictions of lockdown. A sampling frame of four Māori elders speaking on behalf of themselves and their communities in Northland was recruited from health sector network connections and interviews were undertaken and recorded. The rich narratives highlighted an awareness of the generational impact of illness and vaccination and concern about the impact of COVID-19 on vulnerable populations. Despite initial fear about COVID-19, communities described 'safety and comfort' from 'lockdown' creating community resilience and marae, hapu and iwi making major contributions to local crisis response. The well-developed views of these Māori kaumātua about influenza, vaccination and COVID-19 occurred within an environment of contrasting health beliefs and trust/distrust about government and Pākehā-led health services. There was support for the style and content of local health services and recognition and that Pākehā-led health services can be effective when complemented by traditional Māori health values approaches and beliefs. We also noted that the lockdown provided opportunities for these elders to adapt to new technology within a health context. [ABSTRACT FROM AUTHOR]

Background: Immunisation coverage rates vary considerably at the local level across New Zealand and challenges remain with effectively translating best available research evidence into public health practice. This study aimed to translate best practices from high performing general practices into strategies to improve childhood immunisation coverage among low performing practices. Methods: An intervention study was undertaken of general practices with low immunisation coverage rates and a high percentage of the enrolled population being of Māori ethnicity. Intervention groups received customised action plans and support for a 12 month period while control groups received 'business as usual' support. Structured interviews were conducted with key informants from all participating practices to understand current aspects related to childhood immunisation delivery and surveys were conducted to understand how the intervention worked. Collected data were thematically analysed. Results: Ten sites were randomised to either intervention (n = 6) or control group (n = 4). Positive aspects of childhood immunisation delivery included high prioritisation at the practice and staff being pro-immunisation and knowledgeable. Key challenges experienced included inaccurate family contact information and discrepancies with referral processes to other providers. Other challenges noted were building rapport with families and vaccine hesitancy. The action plans included various strategies aimed to improve processes at the practice, contact and engagement with parents, and partnership development with local service providers. Conclusions: Creating customised action plans and providing support to providers were considered as helpful approaches when attempting to improve childhood immunisation coverage rates. Our study supports the notion that one strategy will not solely by itself improve childhood immunisation rates and highlights the importance of having a toolkit of strategies from which to draw from.

INTRODUCTION: The role of healthcare providers and their use of systems is one of the most important factors in vaccination uptake. AIM: To identify reasons and find patterns behind why immunisation providers code the word 'decline' in their system for childhood immunisation events. METHODS: A qualitative study involving face-to-face semi-structured interviews with staff members involved in immunisation delivery. General practices were purposively selected for having either high or low rates of registered children coded on the electronic practice management system as having declined immunisation events. Thematic analysis was undertaken using an inductive approach to link themes to the data. RESULTS: A total of 35 interviews were conducted with practice nurses; 21 were from practices with high rates of registered children recorded as having declining immunisation events, and 14 practices with low rates of declining. Common themes were: effective use of systems, early and ongoing engagement, adequate health care practitioner time and practitioner experience. Practices with low rates of coded decliners had stronger approaches for early and ongoing engagement, and were less likely to use formalised decline forms. As practice immunisation coverage rates improved over time, there was perceived to be less expressed vaccine hesitancy from families. CONCLUSIONS: The reasons for coding individuals as 'decliners' are a complex mixture of individual, community, practitioner and practice systems. Front-line providers need adequate tools, time and resourcing to support effective and ongoing engagement with families. Community factors have influence but can change over time.

INTRODUCTION: Outreach Immunisation Services (OIS) enable children who have not been immunised on time at general practice to be immunised in the community, thereby improving immunisation coverage and reducing equity gaps. AIM: To identify the most effective service delivery models and make recommendations for more effective and cost-efficient OIS delivery in New Zealand. METHODS: Data collection and thematic analysis through a detailed review of OIS contracts and service specifications, an online survey and in-depth interviews with stakeholders and providers, and an analysis of cost data was conducted. RESULTS: In total, 28 OIS providers completed survey questionnaires, 28 OIS staff were interviewed, and cost effectiveness data were obtained from 11 providers. The surveys and interviews identified key themes around identifying clients with the highest needs, effective engagement strategies, staffing requirements, and service challenges. On average, each OIS referral costs NZ$361 (median NZ$257), and each vaccination event costs NZ$636, ranging from NZ$145 to NZ$2403. Characteristics for two separate models of service delivery were identified based on provider size. CONCLUSION: There is considerable range in costs and style of OIS delivery, and efficiencies can be gained. Models need to fit with locality needs and include adequate resourcing, staff with good local knowledge, close relationships with other key child health services and preferably co-location, sustainable funding, and regular service reviews. OIS are part of an effective integrated service that relies on accurate data, positive relationships and a rapid response when children fail to present for vaccination in a timely fashion.

Background Immunisation coverage in New Zealand is lower than what is necessary to prevent large epidemics of pertussis. Primary care is where most immunisation delivery occurs. General practices vary in their structure and organisation, both in a general sense and specifically with respect to immunisation delivery. Aim To identify the structural and organisational characteristics of general practices associated with higher immunisation coverage and more timely immunisation delivery. Design of study A random sample of practices during 2005 and 2006. Setting General practices in the Auckland and Midland regions, with over-sampling of indigenous Maori governance practices. Method Practice immunisation coverage and timeliness were measured. Primary care practice characteristics relevant to immunisation delivery by the practice were described. Associations of these practice characteristics with higher practice immunisation coverage and more timely immunisation delivery were determined. Results A total of 124 (61%) of 205 eligible practices were recruited. A median (25th to 75th centile) of 71% (57-77%) of registered children at each practice were fully immunised, and 56% (40-64%) had no immunisation delay. In multivariate analyses, both practice immunisation coverage (P<0.001) and timeliness (P<0,001) decreased with increased social deprivation. After adjustment for socio-economic deprivation, region, and governance, immunisation coverage and timeliness were better at practices that enrolled children at a younger age (coverage: P = 0.002; timeliness P = 0.007), used one of the four available practice management systems (coverage: P<0.001; timeliness: P = 0.006), and had no staff shortages (coverage: P = 0.027; timeliness: P = 0.021). Conclusion Practice immunisation coverage and timeliness vary widely in New Zealand, General organisational and structural aspects of general practices are key determinants of general practice immunisation delivery.

Aim: The varicella vaccine has been proposed to be added to the childhood immunisation schedule in New Zealand as the fourth injectable at the 15-month event. We sought to understand the perceptions of caregivers and health-care providers regarding the potential introduction of routine varicella vaccination.Methods: A qualitative exploratory study was conducted using semi-structured interviews with caregivers and providers (N = 20) in Auckland. Key themes from the interviews were identified through thematic analysis using a combination of deductive and inductive coding.Results: All of the participants were aware of varicella but levels of awareness varied among caregivers regarding the varicella vaccine. Participants expressed positive support towards universal varicella vaccination and a high intention to vaccinate if available as a routine vaccine. However, many concerns were raised about multiple injections at a single immunisation visit, and participants suggested alternative scheduling options.Conclusion: The results indicated a need to raise awareness among caregivers about the varicella vaccine, focusing on positive health beliefs about vaccination in terms of protecting the child's health and reducing the impact of a child getting varicella on the family. Health-care providers and government health authorities may play an important role in increasing positive health beliefs about the varicella vaccine. Should the varicella vaccine be introduced as proposed, our findings recommend an educational campaign to address both caregiver and provider concerns about multiple injections and how to manage alternative immunisation schedules. These insights may help inform national strategies for the proposed addition to increase acceptance of the varicella vaccination. [ABSTRACT FROM AUTHOR]

New Zealand (NZ) has inadequate vaccine coverage and associated disease outbreaks. International research illustrates the importance of provider behaviour in improving vaccine uptake. To understand the immunisation knowledge, views, concerns and educational needs of NZ family physicians, qualitative and quantitative national data was gathered from randomised telephone surveys. Response rate was 60% with respondents’ characteristics closely matched to key demographics of NZ family physicians. The most significant barrier to improving immunisation rates identified was parental concern over vaccine safety and associated misconceptions. The second major barrier identified was lack of funding to health providers. A clear need for improvement in family physician knowledge of contraindications to vaccines was highlighted. Family physicians expressed a need for better resources to more effectively address parental fears and misconceptions. Strategies to address these issues include an increased focus on family physician educational needs, extra resources to assist with more effective communication to parents and a review of the present funding of providers for immunisation services.

Immunisation is an important public health policy and measuring coverage is imperative to identify gaps and monitor trends. New Zealand (NZ), like many countries, does not routinely publish coverage of immunisations given during pregnancy. Therefore, this study examined pregnancy immunisation coverage of all pregnant NZ women between 2013 and 2018, and what factors affected uptake. A retrospective cohort study of pregnant women who delivered between 2013 and 2018 was undertaken using administrative datasets. Maternity and immunisation data were linked to determine coverage of pertussis and influenza vaccinations in pregnancy. Generalised estimating equations were used to estimate the odds of receiving a vaccination during pregnancy. From 2013 to 2018 data were available for 323,622 pregnant women, of whom 21.7% received maternal influenza immunisations and 25.7% maternal pertussis immunisations. Coverage for both vaccines increased over time, pertussis increased from 10.2% to 43.6% and influenza from 11.2% to 30.8%. The odds of being vaccinated, with either vaccine, during pregnancy increased with increasing age and decreasing deprivation. Compared to NZ European or Other women, Māori and Pacific women had lower odds of receiving a maternal pertussis (OR:0.55, 95% CI: 0.54, 0.57; OR:0.60, 95% CI: 0.58, 0.62, respectively) and influenza (OR: 0.69, 95% CI: 0.67, 0.71; OR:0.90, 95% CI: 0.87, 0.94, respectively) immunisations during pregnancy. Women were also more likely to be vaccinated against pertussis if they received antenatal care from a General Practitioner or Obstetrician compared to a Midwife. A similar pattern was seen for influenza vaccination. Gaps in maternal coverage for pertussis and influenza exist and work is needed to reduce immunisation inequities. [ABSTRACT FROM AUTHOR]

Background We aimed to estimate the protection afforded by inactivated influenza vaccine, in both community and hospital settings, in a well characterised urban population in Auckland during 2014. Methods We used two different comparison groups, all patients who tested negative for influenza and only those patients who tested negative for influenza and had a non-influenza respiratory virus detected, to calculate the vaccine effectiveness in a test negative study design. Estimates were made separately for general practice outpatient consultations and hospitalised patients, stratified by age group and by influenza type and subtype. Vaccine status was confirmed by electronic record for general practice patients and all respiratory viruses were detected by real time polymerase chain reaction. Results 1039 hospitalised and 1154 general practice outpatient consultations met all the study inclusion criteria and had a respiratory sample tested for influenza and other respiratory viruses. Compared to general practice patients, hospitalised patients were more likely to be very young or very old, to be Māori or Pacific Islander, to have a low income and to suffer from chronic disease. Vaccine effectiveness (VE) adjusted for age and other participant characteristics using all influenza negative controls was 42% (95% CI: 16 to 60%) for hospitalised and 56% (95% CI: 35 to 70%) for general practice patients. The vaccine appeared to be most effective against the influenza A(H1N1)pdm09 strain with an adjusted VE of 62% (95% CI:38 to 77%) for hospitalised and 59% (95% CI:36 to 74%) for general practice patients, using influenza virus negative controls. Similar results found when patients testing positive for a non-influenza respiratory virus were used as the control group. Conclusion This study contributes to validation of the test negative design and confirms that inactivated influenza vaccines continue to provide modest but significant protection against laboratory-confirmed influenza.

Abstract: This study aimed to conduct quantitative and qualitative analyses of anonymous data from an immunisation hotline call centre over equal periods in 1999 and 2003. Transcripts for all telephone calls in two periods were analysed using thematic and descriptive statistical analyses and significance testing of comparisons made between data from the two periods. Caller numbers increased from 1010 in 1999 to 3413 in 2003. There was a significant increase in service utilisation by both the public (mostly parents) and health professionals, especially by general practice nurses. The nature of the enquiries shifted according to schedule changes and media stories. Findings are discussed in the context of prominent issues at that time, and suggestions are made for improving communication to meet the needs of both the public and health professionals.
