Consider the situation where, in the course of the research, definitive scientific evidence becomes available that the virus can be transmitted from human to human, but not through mosquitos. Do you believe that the researcher should continue the study as initially approved by the REB?

In this situation, where definitive scientific evidence emerges that the virus can be transmitted from human to human but not through mosquitos, it is important to consider the implications for the ongoing study approved by the Research Ethics Board (REB). To determine whether the researcher should continue the study as initially approved, we can follow these steps:

1. Review the initial research proposal: Examine the original study design, objectives, and methods that were approved by the REB. This will provide a clear understanding of the scope and purpose of the study.

2. Assess the relevance of the new evidence: Evaluate the significance of the newly available scientific evidence regarding the transmission of the virus. Consider its impact on the research question, objectives, and overall study design.

3. Consult with the REB: Engage in a discussion with the REB to present the new evidence and seek their guidance. The REB plays a crucial role in ensuring ethical conduct and protecting the welfare of research participants. Their expertise and input will be valuable in making an informed decision.

4. Consider the ethical implications: Reflect on the ethical considerations associated with continuing or modifying the study. Assess whether the potential risks to participants, if any, have changed with the new evidence. Evaluate whether the study still aligns with ethical principles such as beneficence, non-maleficence, autonomy, and justice.

5. Re-evaluate the study design: If the new evidence significantly alters the transmission dynamics of the virus, it may be necessary to re-evaluate the study design. Consider whether modifications are required to address the updated understanding of transmission routes.

6. Communicate with stakeholders: Engage in open and transparent communication with relevant stakeholders, including participants, funding agencies, and other researchers involved in the study. Inform them about the new evidence and any potential changes to the study.

7. Make an informed decision: Based on the above steps, make a well-considered decision regarding whether to continue the study as initially approved, modify the study design, or halt the study altogether. This decision should prioritize the safety and well-being of participants, adhere to ethical principles, and align with the current scientific understanding.

It is important to note that the specific decision in this scenario may vary depending on the nature of the study, the potential impact on participants, and the guidance provided by the REB.
