United States – The COVID-19 vaccine does not suggest an increased risk for sudden cardiac death among previously healthy young people, according to a study by the CDC that was published today.
Study Overview
Investigators at Oregon Health Authority reviewed sudden death certificate data during the period of June 2021 to December 2022 for cardiac and undetermined causes among individuals aged 16−30. They verified 40 deaths among the same group of people who were either fully immunized with Pfizer or Moderna COVID-19 vaccine, as reported by US News.
Key Findings
Among those 40, there were three deaths recorded within 100 days after the vaccination, of which two were in people who had underlying illness, one that the cause of death could not be determined. According to the survey, the study even proved that no death certificate died from vaccination.
“The data do not support an association of COVID-19 vaccination with sudden cardiac death among previously healthy young persons,” the researchers wrote.
CDC’s Perspective

The CDC has said that myocarditis and pericarditis—inflammation of the heart and the lining surrounding the heart—have rarely been experienced after COVID-19 vaccination. It’s highly frequent among young men within the first week after the second shot. The majority of patients react positively to the therapy/medicine and thus are healed quickly.
The COVID-19 vaccination has advantages over recognized dangers, according to the CDC.
The wrong idea that the vaccines against COVID-19 would lead to deaths in the young people jumped from conspiracy theorists in attracting huge attention on social media with the hashtag #diedsuddenly. Specific events in real life, including the Buffalo Bills player Damar Hamlin’s sudden cardiac arrest, further fed the rumors without grounding onto anything.
Addressing Misinformation
The CDC and other public health organizations during the time faced a severe challenge trying to win people over and make the COVID-19 vaccine appear safe, as renowned figures such as Elon Musk, Joe Rogan, and Robert Kennedy Jr. spread skepticism, as reported by US News.
Nonetheless, according to CDC data, over 81% of all individuals received at least one COVID-19 vaccination.
