 If health care were the only or most important determinant of population health, then an opportunity-based account of justice and health would be right to focus solely on a right to health care and to ignore the more contentious and possibly misleading right claim to health. A right to health care would then be a special case of a right to fair equality of opportunity. Such a right to health care is properly understood as system-relative. The entitlements it involves are contingent claims to an array of health care services that protect fair shares of the opportunity range under reasonable resource constraints.
