The claim: Leaders of countries died unexpectedly after refusing to accept COVID-19 vaccines Socialmediaposts link the assassination of Haitian President Jovenel Moïse and the "unexpected deaths" of other countries' leaders to their opposition to COVID-19 vaccinations. Several posts mention Haiti, Burundi and Tanzania's presidents, and others suggest the fates of other countries' leaders are tied as well. One now-deleted Instagram post pulled the Ivory Coast and Eswatini into the theory with Haiti, Tanzania and Burundi. A meme in atleastfiveotherposts on Instagram and Facebook mentions the same countries. "What do all these world leaders have in common? They all opposed vaccination of the citizens of their countries," the posts read. "What else? They all were recently assassinated or died of suspicious circumstances."
