Covid-19 vaccination uptake by Hapu Mama - How are we progressing?

The Covid-19 vaccine has been recommended for pregnant people (hapu mama) in Aotearoa New Zealand since June 2021. We surveyed people birthing in a tertiary hospital regarding their vaccination status and reasons for this. There were 74% (142/191) of pregnant people who were fully vaccinated. Motivators for vaccination included protection against Covid-19 and antibody transfer to the baby (pepe). Unvaccinated participants worried about vaccine safety. Concerns were raised about the change in official advice without well-communicated reasons for the change. Future vaccine and booster rollouts must be delivered equitably and hapu mama must be a priority group.Copyright © 2022 The Authors.

Access to Vaccination among Disadvantaged, Isolated and Difficult-to-Reach Communities in the WHO European Region: A Systematic Review.

Vaccination has a significant impact on morbidity and mortality. High vaccination coverage rates are required to achieve herd protection against vaccine-preventable diseases. However, limited vaccine access and hesitancy among specific communities represent significant obstacles to this goal. This review provides an overview of critical factors associated with vaccination among disadvantaged groups in World Health Organisation European countries. Initial searches yielded 18,109 publications from four databases, and 104 studies from 19 out of 53 countries reporting 22 vaccine-preventable diseases were included. Nine groups representing the populations of interest were identified, and most of the studies focused on asylum seekers, refugees, migrants and deprived communities. Recall of previous vaccinations received was poor, and serology was conducted in some cases to confirm protection for those who received prior vaccinations. Vaccination coverage was lower among study populations compared to the general population or national average. Factors that influenced uptake, which presented differently at different population levels, included health service accessibility, language and vaccine literacy, including risk perception, disease severity and vaccination benefits. Strategies that could be implemented in vaccination policy and programs were also identified. Overall, interventions specific to target communities are vital to improving uptake. More innovative strategies need to be deployed to improve vaccination coverage among disadvantaged groups.

The assistance gaps in combating COVID-19 in Brazil: for whom, where and when vaccination occurs.

BACKGROUND: Following the emergence of the COVID-19 pandemic, the number of infected Brazilian people has increased dramatically since February 2020, with Brazil being amongst the countries with the highest number of cases and deaths. Brazilian vaccination began in January 2021, aimed at priority groups. This study analysed the spatial and temporal evolution of vaccination in Brazil between the 3rd and 21st epidemiological weeks (EW) of 2021. METHODS: Spatial and temporal analyses were performed comprising 19 EW. Cases were structured into priority groups-elderly population (EP); healthcare workers (HW); indigenous and quilombola populations (I/Q), dose, vaccine (CoronaVac or AstraZeneca), and place of vaccination. A sweep test was performed to identify vaccination rate clusters. Vaccination rates (VR) were calculated according to a spatial window for each Health Region, indicating clusters above/below expected VR. Based on the discrete Poisson probability model, spatial analysis was performed to detect high/low VR clusters, which were converted into Kernel maps. Points were generated from SaTScan analyses associated with Health Region centroids. Temporal analysis of VR was carried out to identify significant trends, and results were converted into temporal cluster graphs. P-value ≤ 0.05 was adopted. RESULTS: Southeast region concentrated most of the vaccines of EP and HW, followed by the Northeast. The latter region had the largest contingent of I/Q vaccinated. In all priority age groups and all regions, a higher percentage of complete CoronaVac vaccination schedules were observed compared with AstraZeneca. The temporal analysis identified high VR clusters of CoronaVac first and second dose in the early weeks, except for the EP; of AstraZeneca first dose, only for HW in the early weeks, and for EP and I/Q in the final weeks; of AstraZeneca second dose for all priority groups in the final weeks. I/Q populations had the lowest general VR. The spatial profile of VR indicated significant regional cluster differences between the priority groups. CONCLUSION: This study highlights the importance of establishing vaccination priority groups, considering the asymmetries that a pandemic can trigger, notably in vast geographic areas, to contemplate the main objective of vaccination: to prevent casualties.

Why is influenza vaccine uptake so low among Aboriginal adults?

Objectives: Determine major barriers to, and facilitators of, influenza vaccination of Aboriginal adults, in order to improve coverage from the current level of 30%.Methods: i) A focus group with 13 Aboriginal Immunisation Healthcare Workers;and ii) a cross‐sectional survey of Aboriginal people aged ≥18 years at the 2017 New South Wales Koori Knockout (29 September–2 October).Results: The focus group nominated poor identification of Aboriginality in general practice. Of 273 survey respondents, a substantial minority (30%) were unaware of their eligibility for free influenza vaccination. More than half (52%) believed the vaccine could cause influenza, 40% reported there were better ways than vaccination for avoiding infection and 30% said they would not have the vaccine if it was offered to them. Regarding health service access, few reported experiencing difficulty (17%), feeling uncomfortable (15%) or being discriminated against (8%), but 53% reported not receiving a reminder from a health professional.Conclusions: Misconceptions about influenza disease and vaccine among Aboriginal people and inadequate identification of Aboriginality in general practice appear to be the greatest barriers to vaccination, rather than health service access in general.Implications for public health: More active communication to and targeting of Aboriginal adults is required;this is even more urgent following the arrival of COVID‐19.
