Robust public health evidence should concede multifactorial causation.

Area of Science:

• Public Health Ethics
• Medical Ethics
• Vaccine Safety

Background:

• The AstraZeneca Covishield vaccine controversy brings rare side effects to the forefront.
• Public health ethics is often conflated with medical ethics, despite distinct practice contexts.
• Current public health approaches favor utilitarianism (greatest good for the greatest number).

Purpose of the Study:

• To examine the ethical distinctions between public health and medical ethics.
• To analyze the justification of rare vaccine side effects within public health interventions.
• To question the ethical permissibility of risking harm to individuals for population-level benefits.

Main Methods:

• Ethical analysis of public health principles versus medical principles.
• Review of evidence interpretation in public health and medicine.
• Case study approach using the Covishield vaccine controversy.

Main Results:

• Public health ethics prioritizes population benefit, often using utilitarian frameworks.
• Medical ethics focuses on individual benefit-risk assessment.
• A divergence exists in how evidence and risk are evaluated in the two fields.

Conclusions:

• Ethical frameworks in public health and medicine require careful differentiation.
• The justification of rare adverse events in public health interventions necessitates a nuanced ethical debate.
• Protecting individual well-being must be ethically reconciled with achieving public health goals.
