Planning to go to Hajj or Umrah?

Do you know that you MUST have a vaccination to get a Hajj VISA?

Join us in our study and we will provide you with the vaccines free of charge.


Study: Optimising immune response to vaccination in Australian Hajj pilgrims

Hajj is one of the great mass gatherings in the world. It involves a lot of crowding and there is a high risk of catching serious infectious diseases such as Meningococcal disease, Pneumococcal disease, and Whooping cough.

In order to be eligible to enter Saudi Arabia for Hajj or Umrah, there is a compulsory vaccine to be taken against meningococcal disease (inflammation of the lining of the brain and blood poisoning).

There are other important vaccines against pneumococcal pneumonia (chest infection) and pertussis (whooping cough). We will offer you vaccines to protect you from these diseases.

We are not testing new vaccines; the vaccines in this study are already registered and are widely used for adults.

No study has been done before to find out the best order of which to give the vaccines recommended for pilgrims.

Can you help us find people who can participate in a study of a new vaccine against Clostridium difficile?

Clostridium difficile is a bacterium that can cause severe diarrhoea after you take antibiotics and may lead to permanent bowel damage and death. It most often affects hospitalised or recently hospitalised people and is difficult to treat. So a vaccine that prevents Clostridium difficile diarrhoea would be very useful.

Please share this information with everyone else you know. Perhaps they too can help us find people who can participate in the study. The more we can find the better. We need 15,000 people including more than 500 Australians to make this study work.

Who can participate?
This study is for two groups of people aged 50 years or more
Group 1: People who are waiting for surgery.
Group 2: People who have been admitted to hospital at least twice in the last 12 months.

A helpful video explaining the study can be found here: Vaccine Study Video

Then you can fully enrol in the study later if you get influenza.
Anyone aged 13 to 65 years can join.

Even if you have not pre-registered your interest before you get sick with influenza you can still call us when you are ill.

Why pre-register your interest?
If you pre-register your interest in this study we will provide you with extra information about the study so you can think about participating before you are ill with the flu.
As soon as you think you have influenza symptoms you must act fast if you wish to join the study. You can be included in the study only if your symptoms have been present for less than 48 hours. Starting treatment even earlier may also mean that your symptoms can be controlled earlier.

If you have the flu right now
Please contact us immediately by telephone. You must act fast if you want to participate in the study.

Other ways you can help
People do not always hear about our studies. Please pass this information along to others who may be able to help.
