  • Public Health

Background:

  • Malaria remains a significant global health challenge, necessitating effective vaccines.
  • Numerous malaria vaccine candidates are under development and undergoing field trials.

Purpose of the Study:

  • To outline key validity issues in assessing malaria vaccine efficacy in field trials.
  • To demonstrate how applying validity principles can enhance data interpretation.

Main Methods:

  • The study reviews established principles of epidemiologic causal inference.
  • It applies these principles to the context of vaccine efficacy evaluation.
  • The focus is on defining measures of efficacy based on exposure and outcome states.

Main Results:
