Current Trials

Sore Throat Study

We are looking for children and young people to take part in a new study investigating the incidence of sore throats, and how we can best prevent them.

What will researchers investigate?

Taking part in the Sore Throat Study will help researchers learn more about:

  • How many children get sore throats
  • What is the most common cause of sore throat in children
  • How sore throats can change during different seasons of the year
  • How a vaccine could be used to prevent sore throats caused by Strep A bacteria

Who can take part?

Healthy children and young people aged 3 to 14 years will be invited to participate in this study.

What does the study involve?

If you and your child take part in this study, we will monitor your child’s health for 12 months. We will ask you to attend a minimum of 3 study visits, which can all be virtual. You will also be asked to provide samples such as blood and throat swabs.

If your child experiences signs or symptoms of sore throat, we will arrange additional visits.

Will I be reimbursed for my time or expenses?

Reasonable costs for your travel will be reimbursed.

CAB study: for pregnant women and their newborn babies

Can your COVID-19 vaccination history help us find out when pregnant women should be vaccinated against COVID-19 to offer the best protection for their babies after birth?

Participants in the CAB study will be asked to visit the Women’s and Children’s Hospital three times:

  • One visit during pregnancy where a blood sample will be collected.
  • Two visits after your baby is born where a blood sample will be collected from your baby
    • at 4-6 weeks of age
    • at 6 months

You will be asked to provide a small sample of breast milk at the second visit.

To compensate you for your out of pocket expenses, you will be provided with a $50 voucher at each study visit.

Influenza Vaccine Study for Children

The purpose of this study is to provide the World Health Organization Collaborating Centre Reference and Research for Influenza in Melbourne with human blood samples collected before and after influenza immunisation. This study will measure the vaccine responses in Australian children, and how well the vaccine strains match what’s circulating out in the community as disease. Results from this study will provide recommendations for the formulation of 2024’s influenza vaccine.

Participation involves:

  • attending up to three clinic visits at the Women’s and Children’s Hospital
  • receiving licensed quadrivalent influenza vaccination
  • having 2 blood samples taken.

A $50 voucher will be provided at each study visit to compensate you for any costs associated with the study. An anaesthetic cream may be used to numb the area prior to blood collection.

If you and your child are interested in participating in this study, please e-mail or, call VIRTU 08 8161 6328.

Whooping Cough Vaccine Study using a nasal spray

We are looking for school aged children 6 to 17 years to take part in a clinical research study looking at the effectiveness of an experimental pertussis (whooping cough) vaccine, given as a fine spray into the nose.

The study will compare the experimental vaccine with a licensed vaccine (BoostrixTM) that protects against tetanus, diphtheria and pertussis.

Participation will last for about 6 months and will include visits to the clinic and telephone calls to check your health.

Reimbursement will be provided for travel and for your time.

To find out more and check if your child is eligible to participate, please contact Donna Martin or visit

PICOBOO: COVID-19 Vaccine Boosting

Are you:

  • An adult aged 50 or over interested in having a third booster dose?
  • An adult aged 18 or over who has not had a second booster dose?
  • A teenager aged 12–17 who is interested in having a first booster dose?

The Vaccinology and Immunology Research Trials Unit (VIRTU) at the Women’s and Children’s Hospital is investigating the most effective, long-term strategies for booster vaccinations to find out whether:

  • Immunity can be maximised by ‘mixing' vaccine booster types and how long this protection lasts.
  • How strategies may need to differ depending on age and previous COVID-19 vaccines.

For more information about PICOBOO, please email or call Meredith Krieg on 8161 7349 or Arockia Sugantharaj on 8161 7452.

FluBub Study

Do you have a new baby who is yet to receive their first scheduled vaccinations?

Babies are at risk of life-threatening complications from influenza. The FluBub study will investigate whether giving babies the influenza vaccine, licensed and recommended from 6 months of age, earlier will provide much-needed protection from influenza.

If you have a new baby who is yet to receive their first scheduled vaccinations, we would love to hear from you. To find out more contact or call Donna Martin on 8161 6328.
