Pneumococcal vaccine study in infants

Research project

The Vaccine & Immunisation Research Group of the Murdoch Children’s Research Institute at The Royal Children’s Hospital and The University of Melbourne is conducting a research study on an investigational vaccine against pneumococcal infections in infants. 



What is Pneumococcal disease?

Pneumococcal disease is caused by a type of bacterium called Streptococcus pneumoniae. This bacterium is a major cause of infection that may be in the ears, sinuses, blood, lungs or brain. 

There is already a licensed vaccine which protects against pneumococcal disease and this is being used to compare to the study vaccine.


What is the study about?

The purpose of this study is to compare the study vaccine with a currently licensed vaccine to study its safety, how well it is tolerated, and how well your child responds to the investigational vaccine.


Who can participate?

Participants must:

  • Be aged between 6 to 12 weeks of age
  • Not have received their 2 month vaccines
  • Healthy 

If your child joins the study,

  • he/she will be allocated to receive either the study vaccine or the licensed comparison vaccine
  • he/she will be followed up for approximately 10 months with a final phone call 5 months later
  • have a number of study visits and phone calls
  • will also be provided other vaccinations required by the National Immunisation Schedule
  • all study visits will be conducted either at The Royal Children’s Hospital or in your home at no cost to you.

This study has been approved by the Human Research Ethics Committee of the Royal Children’s Hospital, Melbourne. This study is sponsored by MSD (Merck, Sharp & Dohme (Australia) Pty Ltd, a subsidiary of Merck & Co., Inc)
