Fact Check: Are COVID-19 Vaccines Useless for Protecting Others From Infection?

Media Bias Fact Check (MBFC) publishes daily vetted fact checks from verified IFCN-approved sources. Each claim is independently reviewed for accuracy and context.


Claimant: Vinay Prasad


Claim: COVID-19 vaccines do not benefit third parties because they do not halt transmission.


Rating: MISLEADING


Explanation: Before the emergence of the Omicron variant, COVID-19 vaccines significantly reduced infection and transmission. Current vaccines still reduce spread for a limited time, though their primary benefit is preventing severe illness and death. Claims that vaccines offer no third-party benefit omit this context.
