Did Marvelous Marvin Hagler Die From COVID-19 Vaccination?

In March 2021, following the death of Hall of Fame middleweight boxer Marvelous Marvin Hagler, rumors swirled online that the 66-year-old had died from receiving a COVID-19 vaccination.

The claim was widely shared on Facebook and Twitter, but appears to have originated from one source only, and has been explicitly refuted by Hagler’s wife, Kay (shown with Hagler in the photograph above).

Hagler, who was undisputed middleweight world champion for a remarkable seven years during the 1980s, died on March 13.
