The Government has started its national Covid-19 vaccine rollout, aiming to administer 1.1 million doses by mid-2021.
These charts track the rollout's progress and compare New Zealand with international efforts.
The bar chart demonstrates how many people have received the vaccine each day since the rollout began in late February. It suggests that the number of people vaccinated from week-to-week was relatively static for the first month of the rollout.
Vaccinations ramped up during the second half of March as some people started receiving the second dose. Easter interrupted this upward trend. The following weeks saw an uptick in doses per day.
This map shows how many people have received a first and second dose of the Pfizer vaccine by district health Board. The size of the outer circle indicates how many people have received their first dose and the smaller inner circle represents the number of people who are fully vaccinated.
Vaccinations are not evenly distributed across health boards. The greatest number of vaccinations are in the health boards that cover Auckland, Waikato and the Greater Wellington area. These districts are where the highest numbers of border and MIQ workers live. As the rollout's focus shifts to high-risk frontline workers we should expect to see more vaccinations in other parts of the country. Note that in some cases a person may travel to a different DHB to get vaccinated.
This table shows that more people of European descent have been vaccinated than any other group.
However, when population size is taken into account, Asian people have the highest rate of vaccinations and Māori have the lowest uptake to date.
Nearly 36,000 more females (88,174) have received a first dose of the vaccine than males (52,237). Despite this, slightly more males (21,611) have received a second dose than females (21,096). The reason for these differences are unclear.
Pfizer is New Zealand's primary vaccine provider. The Government has secured 10 million doses of the vaccine, which is enough to vaccinate 5 million people. Lab tests indicate it is 95 per cent effective at preventing symptomatic infection. Most of these vaccines will arrive in the second half of 2021.
The Pfizer/BioNTech vaccine is the only Covid-19 vaccine to receive Medsafe approval. New Zealand has agreements with three other suppliers, although these vaccines are still awaiting Medsafe approval. These are Janssen vaccine (5 million courses on order), Novavax (5.36 million) and AstraZeneca (3.8 million).
On March 10 the Government announced its vaccine rollout strategy, which assigns New Zealanders into four priority groups. The first two groups have begun receiving vaccinations.
Group 1: February to March
This first group consists of 50,000 border and managed isolation and quarantine workers, their household contacts and the people they live with.
Group 2: March to May
Group 2 includes 480,000 frontline workers and people living in high-risk settings. Vaccinations will start with the 57,000 healthcare workers on community frontlines, and then progress to other healthcare workers. This group also includes older Māori and Pacific people cared for by whānau, their carers and the people they live with. Anyone who lives in the Counties Manukau DHB area who is 65 and older or who has an underlying health condition is also in Group 2.
Group 3: Starts May
The third group consists of approximately 1.7 million higher-risk people, including those aged 65+, people with relevant underlying health conditions and disabled people. It also includes adults in custodial settings.
Group 4: Starts July
The remainder of the general population aged 16 and over form Group 4.
The University of Oxford's Our World in Data project compiles statistics about international vaccination efforts. The numbers reveal uneven access to Covid-19 vaccines across countries and continents. Developed nations are vaccinating their populations at far higher rates than less developed countries.
Many governments are yet to report any Covid-19 vaccination statistics.
Most Covid-19 vaccinations require two doses of a vaccine. A fully vaccinated person has received all required doses of a vaccine. This table tracks how many doses have been administered and how many people have received a full course of a vaccine.
In the early months of the global vaccination programmes, there have been considerable differences in how countries are administering vaccine doses.
Ending the Covid-19 pandemic requires a large proportion of the world's to be immune to the virus. The safest way to do this is through vaccination, which teaches the body's immune system how to respond to the virus.
On December 8, 2020 the United Kingdom became the first country to start rolling out a Covid-19 vaccine to its citizens. The number of daily vaccinations has risen by millions since then.
The speed of the global vaccine rollout is critical. Without timely intervention, the virus could mutate into new strains that resist existing vaccines. Since October 2020, three variants of concern have evolved, two of which are already in New Zealand.
The B.1.1.7 strain, which is also known as the UK variant, was first reported in December 2020. The B.1.351 strain, also known as the South African variant, was reported in January 2021. Both of these variants are more transmissible and have increased lethality compared to other Covid-19 strains.
