The 'Sudden Adult Death Syndrome (SADS) COVID-19 Vaccine Conspiracy' meme emerged as a focal point for online skepticism regarding global vaccine safety initiatives. It typically involves pairing news reports of sudden, unexplained deaths with insinuations about modern medical side effects. While SADS is a medically recognized term for unexpected cardiac deaths, it became a viral keyword used by skeptics to connect various health events to the rollout of COVID-19 immunizations. These memes often utilize a blend of dark humor and social commentary to challenge official health narratives, circulating heavily across platforms like X, Telegram, and Reddit to highlight perceived coincidences.
