Elon Musk took to Twitter late Friday evening to share his personal experience with the second COVID booster shot, explaining he ran into "major side effects."

In a series of tweets, the Twitter CEO said he felt like he "was dying" and that a cousin of his in "peak health" suffered myocarditis, an inflammation of the heart which is listed as a possible side effect of some coronavirus vaccines. 

"I had major side effects from my second booster shot. Felt like I was dying for several days. Hopefully, no permanent damage, but I dunno," Musk said in a tweet.

He added: "And my cousin, who is young & in peak health, had a serious case of myocarditis. Had to go to the hospital."

In a third post, Musk explained it was not his choice to get the second booster but was a requirement to visit a Tesla location in Berlin, Germany. Read more and see tweets here.
