Sudden Adult Death Syndrome (SADS), also known as Sudden Arrhythmic Death Syndrome, is a term for the sudden, unexpected death of adults by cardiac arrest, often used when an obvious cause of death cannot be found post-mortem. SADS was first documented in 1977, however, in June 2022, a conspiracy theory spread online claiming a purported rise in SADS in young people was linked to the COVID-19 vaccine. The conspiracy continued to spread in 2022, largely promoted by those in the anti-vaccination movement, particularly with coronavirus vaccines.
SADS was first documented in 1977 in relation to southeast Asian Hmong refugees in Canada and the United States. A study on SADS was published to PubMED in May 2005, and another was published in May 2007. There have been numerous deaths from SADS reported throughout the 2000s and beyond, including a 21-year-old U.K. woman in 2013 and singer Emma Panas in February 2021.
COVID-19 Vaccine Conspiracy
Around November 2021, conspiracy theorists began suggesting that a rise in "sudden deaths" in young people was supposedly linked to people who take the COVID-19 vaccine. For example, on November 15th, Elijah Schaffer tweeted, "Is this normal?" with a screenshot showing news stories about people suddenly dying, gaining over 4,900 likes in seven months (shown below).

The conspiracy continued to spread in the following days as it was picked up by various websites. For example, on November 19th, 2021, WeLoveTrump.com published an unsourced article suggesting that a purported rise in SADS may be connected to the COVID-19 vaccine, sharing a number of now-deleted tweets about a supposed rise in SADS in the piece. On November 20th, 2021, USA Magazine Studios published the same article, however, there are no peer-reviewed studies to support this theory as of June 2022.
On May 30th, 2022, a 31-year-old woman was reported dead by SADS, increasing discussion about the conspiracy theory in the following weeks. The New Zealand Herald's article about the death features an interview with cardiologist and researcher Dr. Elizabeth Paratz, who said Melbourne's Baker Heart and Diabetes Institute is starting the first registry to track SADS deaths in the country, also saying there are around 750 deaths per year from SADS in New Zealand.
In early June 2022, additional discussions online began to spread regarding the conspiracy theory attempting to link SADS to coronavirus vaccines. On June 4th, Twitter user @BethanyCherisse tweeted, "How many unvaccinated people have died from 'Sudden Adult Death Syndrome [SADS]'? Asking for a friend," gaining over 900 likes in four days.
On June 5th, Twitter user @thedeanpodcast posted, "I'm not hearing many reports of Sudden Adult Death Syndrome occurring among the UNVACCINATED," gaining over 15,000 likes in three days (shown below, left). On the same day, Twitter user @DowdEdward shared the unsourced USA Magazine Studio article, gaining over 2,600 likes in three days. On June 6th, Twitter user @GonzaloLira1968 tweeted, "Friendly reminder: Sudden Adult Death Syndrome did not exist before December 2020. Guess what else didn't exist before December 2020," gaining over 5,700 likes and 1,700 retweets in two days (shown below, right).
