Vaccine manufacturer AstraZeneca acknowledged that thrombocytopenia syndrome (TSS) is a rare risk associated with its COVID-19 vaccine in court documents from an ongoing lawsuit in the U.K. This story has received widespread coverage on conspiracy and tabloid sites where it is misleadingly framed as a “bombshell” admission because this is the first time the company has acknowledged the adverse reaction in court, despite TTS being a known rare risk of both the Astra Zeneca and Johnson & Johnson COVID-19 vaccines since 2021.

Medium Risk Read More +
The story is spreading rapidly across platforms and is circulating globally in multiple languages. However, it is less relevant to American audiences since Vaccines.gov currently offers COVID-19 vaccines from Moderna, Pfizer-BioNTech, and Novavax. If needed, debunking messaging may explain that TTS was first reported as a rare vaccine risk in early 2021 when it received widespread media coverage. The risk is extremely low and linked to AstraZeneca and Johnson & Johnson vaccines, resulting in some countries restricting the use of these vaccines in certain higher-risk populations. Messaging may highlight that this is another example of vaccine opponents blatantly misrepresenting an instance of vaccine safety monitoring working as it should in an attempt to discredit the safety of COVID-19 vaccines.
