Elon Musk, owner of Twitter, the website rebranding as X, is facing heated criticism for spreading misinformation on his platform again. On Tuesday, Musk incorrectly linked COVID-19 vaccines to college basketball star LeBron “Bronny” James Jr. suffering a cardiac arrest during practice. In a tweet, Musk claimed that “we cannot ascribe everything to the vaccine, but, by the same token, we cannot ascribe nothing. Myocarditis is a known side-effect. The only question is whether it is rare or common.”
Because it has been repeatedly shown that this side effect is indeed rare, Twitter initially added a fact-check to the tweet. It was later removed, leaving the original misinformation standing without correction.
