evidence: In June 2024, posts circulated on Instagram claiming COVID-19 mRNA vaccines weren’t actually vaccines under "traditional medical definitions". The posts reference an article published 8 June 2024 on InfoWars, which claimed that the "9th Circuit Court of Appeals has ruled that the COVID-19 mRNA jabs do not qualify as vaccines". [...] Yet the Ninth Circuit Court of Appeals didn’t rule that COVID-19 mRNA vaccines aren’t vaccines—rather, they determined the case should be sent back to the U.S. District Court for the Central District of California, where the case was first argued, for further review. This is the function of an appellate court, as explained by the Administrative Office of the U.S. Courts: [...] As the expression goes, the jury is still out on whether the U.S. federal court system may determine COVID-19 mRNA vaccines to be "medical treatments" rather than vaccines. The plaintiffs argue that vaccines should prevent infection and transmission of the disease, and that COVID-19 vaccines "[do] neither". However, this is a misconception about how vaccines work in general, and isn’t consistent with the data available on COVID-19 mRNA vaccines.
