Musk, 51, took to Twitter to share his experience of the Covid-19 vaccine in response to a retweet of a poll that said 7 percent of adults claimed they experienced major side effects from the Covid vaccine.
The Twitter and Tesla CEO said the second booster ‘crushed me’.
Musk also shared that his younger cousin, who he said was in ‘peak health’, had to be hospitalized after his jab suffering from myocarditis.

‘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 tweeted over the weekend.
He added: ‘And my cousin, who is young & in peak health, had a serious case of myocarditis. Had to go to the hospital.’
Myocarditis is an inflammation of the heart and is named as a possible, but very rare, side effect of Covid-19 vaccinations.
When asked why he had gotten the second booster, Musk said that it was not his choice but because it was a requirement fly to Germany. It is unclear which trip Musk is referring to as he is understood to have visited Berlin in September 2020 and August 2021.
Musk explained further, detailing the which vaccines he had and when.
He said he had Covid-19 before any vaccines were made available, which he described as a mild cold.
‘Then had J&J [Johnson & Johnson] vaccine with no bad effects, except my arm hurt briefly,’ he said.
‘First mRNA booster was ok, but the second one crushed me.’

The original Tweet that Musk was replying to was asking how results from media company and pollsters Rasmussen Reports should be interpreted.
The report said 68 percent of 260 million US adults said they have received the Covid-19 vaccine, 7 percent of which reported major side effects. This equated to 12 million people.
The Centre for Disease Control and Prevention (CDC) said that increased cases of myocarditis and pericarditis – the inflammation of the lining around the heart – were reported around April 2021.
The CDC website said: ‘Data from multiple studies show a rare risk for myocarditis and/or pericarditis following receipt of mRNA COVID-19 vaccines.
‘These rare cases of myocarditis or pericarditis have occurred most frequently in adolescent and young adult males, ages 16 years and older, within 7 days after receiving the second dose of an mRNA COVID-19 vaccine (Pfizer-BioNTech and Moderna).’

Musk repeatedly shared his thoughts on the vaccine. Pictured: Musk attends the Metropolitan Museum of Art’s Costume Institute in New York, May 2, 2022
The CDC said it ‘continues to recommend the Covid-19 vaccination for everyone 6 months of age and older’.
‘The Advisory Committee on Immunization Practices (ACIP) and CDC have determined that the benefits (such as prevention of COVID-19 cases and its severe outcomes) outweigh the risks of myocarditis and pericarditis after receipt of mRNA COVID-19 vaccines,’ they said.
Musk repeatedly shared his thoughts on the vaccine, and has largely been critical of the Covid pandemic and government handling of the outbreak.
Previously, he called fears of the virus ‘dumb’ and falsely claimed that children were ‘essentially immune’.
At the height of the pandemic, Musk also said that the nationwide lockdown was a ‘de facto house arrest’.
Since then he has stressed that he does support vaccines because the ‘science is unequivocal’.
He also acquired and helped deliver some 1,000 ventilators to a California hospital in April 2020.
WHAT IS MYOCARDITIS?
Myocarditis is an uncommon disorder. Most of the time, it is caused by an infection that reaches the heart
Myocarditis is heart inflammation caused by a viral infection, such as COVID-19.
In severe cases, the inflammation can weaken the heart, cause an abnormal heartbeat, or even lead to death.
Symptoms typically include chest pain or shortness of breath.
Patients can treat the condition with medication aimed at regulating heartbeat and improving heart function. Some rare cases have required patients to have a device implanted in their heart to regulate heartbeat.
Myocarditis is a mild, temporary condition in the vast majority of cases, experts say.
Heart inflammation is uncommon in pro athletes who’ve had a mild COVID-19 infection and most don’t need to be sidelined, according to a 2021 study conducted by major professional sports leagues.
