FDA to issue most serious warning on Covid vaccines

The U.S. Food and Drug Administration (FDA) plans to issue its most serious warning regarding Covid-19 vaccines, according to a report by CNN. This warning, known as a "black box" warning, is intended to inform the public about potential risks associated with the vaccines.

The FDA"s decision comes amid ongoing discussions about vaccine safety and efficacy. The agency has previously issued warnings related to Covid-19 vaccines, but this new measure represents a significant escalation in the regulatory approach to vaccine communication.
