Vaccine hesitancy growing in at-risk communities, providers blame social media misinformation

A growing number of families living in communities most vulnerable to infectious disease outbreaks are
refusing to have their children vaccinated
.
Immunisation experts fear this worrying trend will make it impossible to reach the government's target of 95 percent coverage by 2030.
At Ngā Mataapuna Oranga primary health organisation in Western Bay of Plenty, health workers are not passively waiting for whānau to bring their babies in for vaccination.
A manager and kaiwhakahaere, Jackie Davis, said it had managed to boost immunisation rates by 10 percent in the last year through the heroic efforts of nurses, community workers and GPs.
"[We've even had] community teams lurking in bushes, waiting to ambush mums coming home from shopping," she said wryly.
In a league table of primary health organisations (PHOs) published by Health NZ, Ngā Mataapuna Oranga has the highest decline rate, with 25 percent of families refusing immunisation.
As a small PHO, with just four general practices, it only took a handful of families to decline immunisation to drop its rates below target, Davis pointed out.
However, she admitted it was up against persistent anti-vaccination propaganda, which
spreaded like contagion via social media
.
"I guess their promotion is just as good as our promotions are, so they counter a lot of the work we do."
Nationally, 79.3 percent of two-year-olds were fully vaccinated in the first three months of the year - marginally better than at the same time last year.
In some regions however, rates were much lower: Northland had just 66.4 percent coverage, while in Tairāwhiti and Bay of Plenty, it was around 68 percent .
Davis said the Covid pandemic damaged trust in the health system and it was taking time to rebuild those relationships.
"I think too that we have to balance our attempts at immunisation in relation to our relationships with our families.
"To put it bluntly, sometimes we're going two or three times to the same families. And at the end of the day, from their perspective, they're over us."

Infectious disease expert professor Peter McIntyre, from Otago University, said before Covid, decline rates for childhood immunisation were around 5 percent.
However, for about one in three PHOs in those Health NZ figures, the decline rate was now more than 10 percent.
"This substantial increase in the proportion of families declining, effectively makes that impossible."
Unfortunately, vaccine distrust had got a stronger hold among Māori and
Pacific communities
, which already had more "delayed" immunisations, he said.
"What the decline figures are telling is that these are people who are indicating they just don't intend to get their child immunised full stop, which is a development that's really worrying, because decline is a whole lot worse than delay."
Full coverage remained a worthy goal, he said.
"But if we really have to choose - which maybe at this stage we do - we want to focus on: How good is our
protection against measles
? What's that looking like? What do we have to do about it? And maybe whooping cough as well. And meningococcal B."
Ngāti Porou Oranga in Tairāwhiti recorded the lowest coverage with just 38.5 percent of two-year-olds fully vaccinated in the first three months of the year.
No-one from the PHO was available to comment.
Eastern Bay Primary Health Alliance in Bay of Plenty said its figures had improved: 58.4 percent of enrolled tamariki were fully immunised as of 1 July, up from 52.5 percent in the previous quarter.
Chief executive Katarina Gordon said however it was also seeing a growing number of whānau "expressing hesitancy or choosing to decline immunisation".
"We're seeing a steady increase in vaccine hesitancy particularly among younger parents and caregivers.
"Some are actively declining, but many are simply unsure or misinformed. Social media misinformation, past experiences of the health system, and general mistrust all contribute to this hesitancy."
Many whānau were living in rural or remote areas, with limited access to transport, housing instability and economic hardship, which meant day-to-day needs often took priority over preventive healthcare like immunisations, she said.
Health providers were struggling themselves with limited clinic availability, workforce shortages (especially nurses and outreach staff) and high demand, which meant some whānau faced long wait times or limited options for appointments.
"Mobile outreach services help, but capacity is stretched, and funding is not always available and or sustainable."
Despite these challenges, Eastern Bay Primary Health Alliance continued to work with its practice network, outreach teams, Hauora Māori partners the National Public Health Service and Te Whatu Ora Health NZ to boost immunisation rates.
"We remain committed to ensuring all interactions with whānau are timely, respectful, and culturally safe."

'It takes a toll on people' - long-term mental health support needed for flood victims
The Tasman region has been hit by two flood emergencies and repeated orange heavy rain warnings in recent weeks. Photo: Supplied/ Jodie Reed People in the Tasman region will need long-term mental health support after devastating winter floods, a mental health advocate says. Locals have endured two flood emergencies and repeated orange heavy rain warnings in recent weeks. The Rural Support Trust said many already flood-affected residents were feeling tired and very anxious as more heavy rain fell on the region. Mental Health Foundation chief executive Shaun Robinson said when disaster struck, people were usually in a more practical mode, adrenaline pumping, and doing what they needed to do to respond. It was the aftermath that could leave some people feeling depressed, hopeless or isolated - a natural human response to a very difficult situation, he said. "It's then when you have to look at the aftermath and the fact that things are not going to go back to the way they were, that can be really difficult and that's when it can really start to affect people's mental health and well-being," Robinson said. "People need to really create a new sense of what living in that place is going to be about." He described what was happening in Tasman as an "ongoing natural disaster" rather than separate floods. Community connections made a big difference. "What we've seen and what farmers and rural people have told us from the Cyclone Gabrielle experience was that it was communities continuing to work together that made the difference to them continuing to have hope and a sense of not being alone in this and therefore boosting their resilience and mental well-being," he said. The government also needed to look at what support it provided, not only offering counselling, Robinson said. "Whatever communities do and whatever government does to respond to a situation like Tasman, really needs to be boosting those community networks, those community responses to this ongoing crisis," he said. "It is the months and even years after these major events that we need to encourage that sense of community resilience and actually put some work into creating and sustaining that community resilience. "That is certainly what the government is responsible for resourcing as part of its response to natural disasters." It was important that communities felt supported and did not feel like the country had forgotten them, he said. Robinson hoped people would feel comfortable to reach out and ask for support if they needed it. Rural Support Trust Nelson Tasman chair Richard Kempthorne said people were getting tired after heavy rain has battered the region multiple times within the space of weeks. "It certainly takes a toll on people. Many of these people who've lived in the area for years and they've lived on their properties for years and they've had flooding before," Kempthorne said. "But very few people have had a flood to this extent." Many people in the Motueka and Wai-iti valleys relied on their business in the area for income so flooding also threatened their livelihoods, he said. "During the flood event, it will just be step back and let it happen. Once it drops, what's the damage left and then what can we do? "What we encourage and what people I think are actually quite good at is to chopping it down into - what do I need to do first and what are the steps I need to take? Not trying to do it all at once and just bite one chunk off at a time." Kempthorne said people should reach out for help as there was support available. That included Taskforce Green which was going onto farms to clear debris, Big Bake in Wakefield which was preparing food for rural communities, Federated Farmers, and the Rural Support Trust which offered counselling support.

What you need to know about Wednesday's nurses strike
Nurses held an 8-hour strike last December. A new strike is planned for 24 hours on Wednesday. Photo: RNZ / Samuel Rillstone Nurses are going on strike on Wednesday. About 36,000 nurses, midwives and health care assistants will be off the job from 9am Wednesday to 9am Thursday. Last-ditch negotiations on Monday failed to reach an agreement . There will be pickets and marches throughout the country. Nurses are concerned about staffing levels and safety . The latest pay offer was also dismissed as a "massive backward step" . Health NZ is offering a 3 percent pay rise over 27 months, plus two lump sum payments of $325. NZNO's counter-offer seeks a 5 percent pay rise over two years, along with $2000 flat rate increases for senior positions. The union also seeks to restore a Tikanga Māori allowance. "The average salary for both senior and registered nurses, including overtime, PDRP allowance, and penal rates, is $125,662, Health NZ said . "Members also need a wage offer that enables them to meet the rising cost of living without them and their whānau going backwards financially for the important mahi they do," said Paul Goulter, chief executive of the New Zealand Nurses Organisation. "We believe the offer we have made to the union is a fair one given our current financial constraints," Health NZ said. In a statement, Health New Zealand said "we are disappointed that the New Zealand Nurses Organisation (NZNO) is taking strike action when there is a fair offer on the table." "We are concerned about the impact strike action will have on patients who are waiting for planned care." Goulter said the latest offer from Health New Zealand ignores worries about safe staffing . "Patients are at risk because of short staffing. Nurses, midwives and health care assistants are stretched too thin and can't give patients the care they need. This is heartbreaking for our exhausted members who became health care workers because they want to help people." A safe staffing agreement was dropped from negotiations with Health New Zealand. Figures obtained by NZNO from Health New Zealand show surgical hospital wards were short-staffed more than half of all day shifts last year. Health New Zealand said in their statement it also seeks to keep nurses and patients safe. "While we are aware of NZNO's commentary in recent weeks we would like to reassure New Zealanders that Health NZ is completely committed to safe staffing. "For us safe staffing in a busy hospital environment includes the skills mix of the staff, the way care is provided, strong clinical judgement, flexibility and thoughtful decision making from our experienced leaders on the frontline. We take responsibility for operational and patient safety decisions seriously as we are accountable for the safety of patients who access our services." Paul Goulter, chief executive of the New Zealand Nurses Organisation. Photo: RNZ / Nate McKinnon Goulter said the key issue was making sure there was enough staff to "ensure patient safety", which was "foremost in the minds of our members" during negotiations. "While, obviously, there's a wage element, we're trying to do our best to ensure we get staffing that's appropriate to meet what patients need and we seem to have come up short on that," he told RNZ recently. Negotiations began last October, but the union said bargaining had stalled over "big ticket items" centred on public safety. Nurses also walked off the job in strike in December for eight hours. "We are striking because patient safety is at risk every day due to chronic understaffing and under-resourcing," Wellington nurse Hilary Gardner said. "We simply don't have enough nurses to provide the level of care our patients need and deserve. It's not safe, and it's not fair - for patients, their whānau, or the staff trying to care for them. We've raised concerns time and time again, but nothing changes - so now we're taking action to stand up for safer care." Acute and emergency services will still be provided, including maternity care, intensive care, ambulance services and emergency departments. Patients already in hospital will still receive ongoing care. "... The public can be reassured that we have an agreement with NZNO for life preserving services support throughout the strike and our hospitals and emergency departments will remain open," Health NZ Chief Executive Dr Dale Bramley said. "To maintain patient safety, most clinics will be closed. However, if you have a hospital appointment, please come to your appointment unless we have contacted you directly to reschedule." However, most appointments for the strike days will be rescheduled. "It is estimated that 4300 planned procedures and specialist appointments would have to be postponed should the 24-hour strike action on 30 and 31 July go ahead," Dr Bramley said. Aged residential care, St John Ambulance, GPs and hospice services are not affected by the strike and will carry on as normal. Anyone unsure about whether they need emergency department care should contact their GP or call Healthline 0800 611 116 for free advice. Photo: RNZ / Samuel Rillstone The union does not rule out further action if their concerns aren't met, Goulter said. "Our members have indicated this strike is just the beginning and they are in it for the long haul." "Our members don't take this action lightly. They are striking because they are exasperated with being short-staffed and their patients being put at risk because Te Whatu Ora refuses to resource safe staffing levels and instead staffs to an arbitrary budget set by the government. "The public know that when there aren't enough nurses, patients wait longer to get the care they need. Critical observations and treatments may be delayed, errors are more likely and health outcomes worsen. A lack of nurses has reduced numbers of elective surgeries for years and contributed to longer waiting times and the current backlog. "Any member of the public who has been to a hospital recently knows the reality for patients and the nurses, midwives, health care assistants and kaimahi hauora who care for them."

More support needed for rural Māori looking after whānau with dementia, researchers say
Dr Makarena Dudley. Photo: University of Auckland / Supplied Too many rural Māori whānau are caring for loved ones with dementia - or mate wareware - without support, diagnosis or the information they need, according to two leading brain researchers. Sir Richard Faull, director of the Centre for Brain Research at the University of Auckland, and deputy director, Māori, Dr Makarena Dudley, say Māori and Pacific people are affected by dementia more than any other group. They spoke to Nine to Noon about travelling around the country visiting marae sharing information and hearing stories. So far they've held hui at marae in the Far North and Whanganui, and more are planned. Dudley said the goal is to reach out to all Māori communities, particularly those in remote areas, to share information about the condition and gather the kōrero of caregivers. "Some of these caregivers are desperate for support, they're caring for sometimes loved ones who are exhibiting very challenging behaviours. Looking after somebody who has mate wareware particularly in the more severe stages of the condition can be extremely challenging and often even amongst Māori families that responsibility is often left to one person." Providing support for caregivers is one of the major parts of this program, Dudley said, many are isolated in rural areas and don't know where to turn to for help. "There was an international study done actually across a number of nations that caregivers often die more than the person they are tending to." Aotearoa is in the midst of conducting a nationwide prevalence study, which has another year to go, but once it's finished there will be accurate data about the extent of dementia among Māori, she said. The goal of travelling around to marae is to reach out to all Māori communities to give them information about dementia and listen to their experiences with the condition, she said. "Then we can take that information back with us and decide okay so here are the issues, here are the problems, how are we going to address this, how are we going to help to fix this and so we've visited around about 25 marae so far. .. we've spoken to hundreds of kaumātua, we've listened to their stories, some of them quite heartbreaking. "One of the main themes that's come across from all these visits is that there is a profound lack of information available to the Māori community and more so for those who are living more remotely not only is there a lack of information but there are virtually no services available to them." The Centre for Brain Research is currently funding a program to support caregivers in Ahipara, Dudley said so far its been a success and it's service that doesn't require a lot of funding. Dudley has also helped develop an app to help Māori affected by dementia. The app provides all the basic information a whānau might want to know about dementia, she said. The app provides all the basic information a whānau might want to know about dementia. Photo: supplied Faull said the ethos of the Centre for Brain Research is not only to do research but communicate that research to people and then listen to them. Faull said it's a privilege to go out to marae to listen to people and put that ethos into action. "We are actually seeing an absence of services in so many ways, this is for Māori and non-Māori, but especially for Māori so that's why it's important for us to go out and tell them about the risk factors." If you address the risk factors you can reduce the prevalence of Alzheimer's by about 60 percent, he said, so communicating that to people on the ground is vitally important. Sir Richard Faull. Photo: University of Auckland / CBR Dudley said when developing a model for treating dementia that resonates with Māori they need to use the information from both knowledge bases, western science and mātauranga. "They need to know information from both worlds." "Because there is a lot of information out there now but Māori don't really buy into it, it doesn't resonate with them because its not in their speak, it's not familiar to them the language that is used the way it is introduced to them." The Centre for Brain Research is currently working to produce a model that works for Māori, she said, once that happens she believes progress will be made in reducing incidents of dementia.
