Here are some answers to common questions that may be helpful.

How does the vaccine work?

The COVID-19 vaccine works by teaching your body to fight the virus and protects you from
getting sick:

1. The vaccine sends a set of instructions to teach your body how to fight the COVID-19 virus.
2. With these instructions your body learns to recognise the COVID-19 virus and use antibodies against it. Antibodies stop the virus from infecting your cells and help to kill it.
3. That means if you come into contact with the COVID-19 virus in the future, your body will have the right tools to protect itself so you are less likely to get sick.

Is the vaccine safe?

The Pfizer vaccine has been thoroughly assessed for safety by our own Medsafe experts.

Medsafe only grants consent for using a vaccine in Aotearoa once they’re satisfied it has met strict standards for safety, efficacy and quality.

This is the same process used to assess other vaccines, like the flu, measles, and tetanus vaccines. There have been no shortcuts taken in granting approval.

The Pfizer vaccine has been used successfully by millions worldwide and is highly effective at preventing severe illness and death. It continues to be monitored for safety.

Why was it developed so quickly?

Because the mRNA vaccine is not new technology and has been studied for over a decade, including for the development of other vaccines such as the seasonal flu vaccine, researchers had a head start.

This is the first time scientists and governments from around the world have united to develop a vaccine. This global collaboration meant they could spend an enormous amount of time and money into developing the vaccines very quickly without taking any shortcuts in the necessary processes or compromising safety. This also meant that the various stages of research development happened at the same time.

What I can expect when I get the vaccine?

You can book through your GP or through vaccination centres:

• Book online through Book My Vaccine
• For a group booking, call the COVID Vaccination Healthline on 0800 28 29 26 (8am-8pm)

When you arrive to receive your vaccination, the vaccinator will offer you the opportunity to ask any questions.

You will need to relax and sit still. Some find it helpful to listen to music, or you may choose to have a support person with you.

The vaccinator will then inject the vaccine into your arm. You can look away or close your eyes if you need to. You may feel a pinch or scratch when the needle goes in.

You’ll then be asked to get your second dose of the vaccine six weeks or more after your first dose.

Are there any side effects?

It is common to experience mild side effects, such as muscle aches, pain at the injection site or headaches.

These are more commonly reported after the second dose and are actually a sign that your body’s immune system is learning to fight the virus. They don’t last long and won’t stop you from having a second dose or going about your daily life.

There are some side effects that are more serious but very rare, like a severe allergic reaction or an inflammation of the heart. If you develop difficulty breathing, a racing heart, chest pain or feel faint immediately or in the days after the vaccine, you should seek medical attention.
