The WellKiwis Infant study is a ground-breaking influenza research study and the first of its kind! Unlike a common cold, influenza is a serious illness that affects millions of people globally, and young children, pregnant women, older adults and people with underlying medical conditions are particularly vulnerable.

Join the WellKiwi Infant study, be part of the growing community and help us develop better vaccines, prevent future pandemics and improve community health. Babies could hold the clue to save millions of lives around the world.

Throughout the study, we ensure you and your baby receive fantastic benefits.

Eligibility Criteria

  • Are you living in the Wellington region?

  • Are you expecting a baby?


What is the WellKiwis Infant study?

We are looking for expectant mums living in the Wellington Region to join our study. We will then follow the child from birth to seven. The WellKiwis study aims to discover how the very first encounter with the flu or flu vaccine can influence ongoing immune responses. This study provides an opportunity to understand how imprinting affects individuals’ immune memory and their ability to confront subsequent exposures to the flu.

The WellKiwis Infant study is a unique study happening in Wellington and has global significance. There are two sister sites in Los Angeles and Nicaragua. The study is led by scientists at the Institute of Environmental Science and Research (ESR).

What are the benefits of taking part for you and your child?

  • Your child will have healthcare professionals looking out for their wellbeing, and those in your family or whanāu, for the duration of the study.
  • Every time your WellKiwis child catches a cold or flu during flu season, a nurse will be in contact and may come and visit you at home.
  • You will find out quickly if your child is infected with the flu or another respiratory virus (including COVID-19) and get access to the right support to keep them healthy and well.
  • You will be part of a global study to provide information to help develop longer-lasting flu vaccines and hopefully create the universal vaccine.
  • You will receive a gift card valued at $30 each time a sample is taken to thank you for your time and participation.
  • We regularly hand out gifts such as books when we come and visit.
