Home Reports Summary Report Part Two: Lessons learned from Looking Back 11 - Vaccination
Introduction | Kupu whakataki
From the start of the pandemic, the prospect of a safe and effective COVID-19 vaccine provided a beacon of hope in an otherwise bleak global landscape. Government messaging presented vaccination or new treatments as the justification for – and pathway out of – the initial elimination strategy and the restrictions it involved. This message clearly resonated with many members of the public, including some who made submissions to our Inquiry:
“Lockdowns were totally necessary until such time as a vaccine was approved and available. We saw what was happening in the rest of the world and it was horrifying.”
Vaccination was fundamental to the effectiveness of Aotearoa New Zealand’s pandemic response. By the time community transmission of COVID-19 became well-established, most of the population had received at least one dose of the vaccine and a large proportion had received both initial doses. From this point on, optimising population immunity through vaccination was a crucial pillar of the country’s long-term approach to managing the virus.
The Inquiry described the process of identifying, procuring and approving a suitable vaccine, which proceeded alongside the development of Aotearoa New Zealand’s vaccine strategy. We surveyed how the vaccine was made available to the community (referred to as ’the vaccine rollout’) and the subsequent provision of boosters. We also looked at the steps taken to sustain population immunity once Aotearoa New Zealand moved on from the elimination strategy to a minimisation and protection approach.
The evidence we reviewed highlights some positive outcomes: vaccination undoubtedly protected Aotearoa New Zealand from the very high burden of illness and death many other countries faced, and the national rollout achieved high levels of vaccine coverage. However, the evidence also reveals missed opportunities to ensure that vaccine uptake and access were equitable across the community.
Note: detailed information about these topics and what occurred during Aotearoa New Zealand’s response to COVID-19, along with our complete assessment, can be found in the corresponding Looking Back chapter in our main report.
We also assessed the management of the vaccine rollout, the way vaccine hesitancy and misinformation affected vaccine uptake, and the efficacy of processes for procuring and approving the vaccine. The Inquiry assessed vaccine mandates and these are discussed in Chapter 12, along with vaccine passes.
In the main report, this Chapter includes a case study (spotlight) on the effectiveness of Māori and Pacific health providers in the vaccine rollout.
Through the Inquiry’s public submission process, people shared a range of perspectives and experiences with us in relation to vaccination. Some felt that the Government did a good job of obtaining a COVID-19 vaccine quickly and were grateful that these were free and easy to get. People also praised the Government for observing which vaccine was the safest and most effective by watching the rollout overseas, so that it could obtain the best one available. We also heard that people felt the vaccine was effective in helping to protect vulnerable communities.
Others told us that the vaccines were rolled out too slowly and more people should have had earlier and easier access to them. Some submitters commented on instances where people were given incentives (such as vouchers and food) to get vaccinated; some were supportive, but others felt it could be manipulative. We also heard that some people felt they couldn’t give informed consent because there wasn’t enough information about the vaccine’s side effects or what it was made of. People also shared concerns on how the Government communicated with the public about the safety of the vaccine and how well it worked.
For future pandemics, people suggested:
- more people would be willing to get vaccinated if there was better education and messaging about vaccinations
- the Government ensures Aotearoa New Zealand gets earlier access to vaccines.
“I believe that the vaccination rollout, from a standstill, was an impressive feat; clearly we learnt as we progressed along the way.”
“That we were able to get most of our population vaccinated before COVID-19 took hold in New Zealand means that we have never felt the worst effects of the pandemic. Despite COVID-19 being now prevalent in New Zealand…our deaths from COVID-19 continue to be much, much lower than had we taken a different approach.”
“My GP couldn’t/wouldn’t tell me what was in the vaccine, or elaborate on possible side effects, he just kept saying ’safe and effective’ – so I couldn’t give informed consent or get an exemption.”
Note: this material is taken from the Inquiry’s Experiences Report, which is a summary of the public feedback submitted to Phase One of the Inquiry during early 2024.
1. In combination with the elimination strategy, vaccination was fundamental to the effectiveness of the country’s COVID-19 response.
- From the first weeks of the pandemic response, vaccination was recognised as the likely key measure that would allow Aotearoa New Zealand to reconnect with the rest of the world while protecting the population from the levels of COVID-19 illness and death seen in other countries.
- While Aotearoa New Zealand’s vaccination programme started slightly later than those in some other countries, it quickly achieved very high coverage: more than 80 percent of adults had received two vaccine doses by the end of 2021. This meant the vast majority of New Zealanders had been fully vaccinated before they were exposed to COVID-19 infection.
- The vaccination programme was also successful in ensuring people at highest risk received a third ’booster’ dose within a few months of their original vaccination. This meant they benefited from high levels of protection at the point Aotearoa New Zealand experienced its first COVID-19 ’peak’ with Omicron in early 2022.
- In addition to the protective effect of the elimination strategy, vaccination is estimated to have saved more than 6,500 lives and prevented more than 45,000 hospitalisations from COVID-19 in Aotearoa New Zealand.
2. The vaccine procurement process was appropriate and effective. International relationships were important in securing timely vaccine supplies to support the rollout.
- Aotearoa New Zealand used a portfolio approach that appropriately invested in several potential vaccine sources to be confident of securing an adequate supply. While this approach eventually resulted in surplus vaccine doses (donated to Pacific countries), it represented a prudent ’insurance’ policy given the historical expectation that only one in five candidates being developed results in an effective vaccine.
- Advance purchase agreements were obtained for enough doses to immunise the entire population with a single vaccine – the Pfizer ’Comirnaty’ vaccine. While other vaccines were subsequently purchased, Pfizer remains the country’s first-line vaccine option for COVID-19.
- Good relationships with other countries (particularly Spain and Denmark) were important in addressing supply challenges and ensuring Aotearoa New Zealand had sufficient vaccine to support the national rollout.
3. The Pfizer vaccine underwent full assessment and received provisional regulatory approval prior to being rolled out.
- The Pfizer vaccine underwent independent assessment and received provisional approval by Medsafe (the national medicines regulator) before being rolled out in Aotearoa New Zealand.
- The Medsafe assessment process provided assurance about the quality, safety and efficacy of the vaccine for the New Zealand population. The process also allowed regulators to review the most up-to-date evidence, including data not available to regulators in other countries. An expedited review process meant the Pfizer vaccine received approval before the first doses arrived in the country.
4. An enormous nationwide effort underpinned the vaccine rollout, which achieved very high levels of population coverage. At the same time, some opportunities were missed to ensure the vaccine reached vulnerable groups as equitably as desirable.
- The COVID-19 immunisation programme was very effective in quickly delivering high levels of vaccine coverage at an overall population level.
- The rollout of the vaccine involved difficult trade-offs between the need to manage operational constraints, the desire to vaccinate the population as quickly as possible, and recognition that more tailored approaches would be needed to reach some population groups (including Māori and Pacific communities, and people living in more rural areas). With hindsight, opportunities to ensure more equitable vaccination uptake were missed by not involving Māori, Pacific and community-based providers earlier in parallel to the main vaccination programme.
- Once Māori, Pacific and other community-based providers were brought into the vaccine rollout, they were highly effective in supporting vaccine uptake within their communities.
- Faster vaccine rollout and uptake among Māori and Pacific people would have resulted in fewer hospitalisations and deaths during the Auckland Delta outbreak, and likely shortened the final Auckland lockdown.
5. Vaccine hesitancy emerged as a growing challenge to the rollout, fed by exposure to misinformation and disinformation and declining trust in government within some communities.
All vaccines have the potential to cause harm to a small number of individuals. There is potential to strengthen the communication of risk at the time people are vaccinated.
- The vaccine rollout was challenged by declining trust and confidence in parts of the population, exacerbated by a proliferation of misinformation and disinformation. The influence of these factors was particularly apparent among younger people, in some Māori and Pacific communities, and in rural areas.
- Providing direct ’rewards’ (such as vouchers) to encourage vaccination was effective in the short term but raises ethical challenges including the impact of perverse incentives and the risk that future vaccination programmes may be less successful if they do not provide such rewards. A better approach is to improve vaccine access and address the root causes of vaccine hesitancy in vulnerable communities. In a future pandemic, direct incentives to boost vaccination should be used with caution.
- All vaccines have the potential to cause harm to a small number of individuals. While Medsafe and the Ministry of Health sought to keep people up to date with emerging evidence of rare complications, the Inquiry understands there is potential to strengthen the communication of risk at the time people are vaccinated. Doing so would support both informed consent and awareness of any subsequent symptoms that require medical attention.
