The new COVID vaccine has different names depending on the source. According to the American Medical Association, the official name for the new XBB.1.5 monovalent version is the 2023-2024 COVID vaccine, or simply the updated COVID vaccine. On the other hand, Johns Hopkins reports that the updated COVID vaccine approved by the FDA this week is based on a variant called XBB.1.5. The new vaccine is also referred to as the "2023-2024 covid-19 vaccine" or simply the "new covid shot". It is important to note that the new vaccine is a booster shot, and not a completely new vaccine.
