New Zealand on Monday reported what authorities said was the country’s first recorded death linked to the Pfizer COVID-19 vaccine.

The information was released by the health ministry following a review by an independent COVID-19 vaccine safety monitoring board of the death of a woman after receiving the vaccine. The ministry’s statement did not give the woman’s age.

The board considered that the woman's death was due to myocarditis, which is known to be a rare side effect of the Pfizer COVID-19 vaccine, the statement said. Myocarditis is an inflammation of the heart muscle that can limit the organ’s ability to pump blood and can cause changes in heartbeat rhythms.

”This is the first case in New Zealand where a death in the days following vaccination has been linked to the Pfizer COVID-19 vaccine,” the health ministry said.

The Pfizer media team in New Zealand did not immediately reply to an emailed request for comment.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

The case has been referred to the coroner and the cause of death has not yet been determined, the health ministry said.

The independent board, however, did consider that the myocarditis was probably because of the vaccination.

The board also noted that there were other medical issues occurring at the same time which may have influenced the outcome following vaccination.

”The benefits of vaccination with the Pfizer COVID-19 vaccine continue to greatly outweigh the risk of both COVID-19 infection and vaccine side effects, including myocarditis,” it added.

So far the Pfizer/BioNTech, Janssen and AstraZeneca vaccines have been provisionally approved by New Zealand authorities. However, the Pfizer vaccine is the only vaccine that has been approved for rollout to the public.

New Zealand is battling an outbreak of the Delta variant of COVID-19 after nearly six months of being virus free.

It reported 53 new cases on Monday, taking the total number of infections in the current outbreak to 562.

A nationwide lockdown was enforced earlier this month to beat the spread of the Delta variant.
