Participant Information Statement

Please go to the bottom of the page after reading the participant information statement and click NEXT to complete the survey. Thank you.

(1)     What is this study about?         

Research conducted in the past 15 years has shown that vaccination with Gudair® substantially reduces mortalities but sheep in some flocks continue to shed Mycobacteria in their faeces and remain infectious. There is limited information about why the efficacy of Gudair® is different on different farms and what would happen if the program of annual lamb vaccination is discontinued. You are invited to take part in this exciting research to understand the reasons for this differential effectiveness of the Gudair® vaccine in different flocks and to understand the outcomes of cessation of annual lamb vaccinations.

You have been invited to participate in this study because you are a sheep producer. This Participant Information Statement provides you information about this research. Knowing what is involved will help you decide if you want to take part in the research. Please read this sheet carefully and ask questions about anything that you don’t understand or want to know more about.

Study findings may be published but you will not be individually identifiable in these publications. The results will be presented in scientific conferences and published in peer reviewed journals. 

The information and the questionnaires kept confidently during the study period will be accessible only to the investigators. Following the research period, the questionnaires will be stored safely by the principal investigator for an additional five years. Afterwards, the documents will be destroyed by shredding and the information stored in the hard drive will be erased using commercial software. The data may be used in a future project but will not be provided to third parties.
