I found Covid Vaccines at the FDA's Emergency Use Authorization page, which has a rather extensive Q&A section.
https://www.fda.gov/vaccines-blood-biologics/vaccines/emergency-use-authorization-vaccines-explained~~~~~~~
The following notes there is a FACT SHEET...which I will next try to find on their site:
>How will vaccine recipients be informed about the benefits and risks of any vaccine that receives an EUA?FDA must ensure that recipients of the vaccine under an EUA are informed, to the extent practicable given the applicable circumstances, that FDA has authorized the emergency use of the vaccine, of the known and potential benefits and risks, the extent to which such benefits and risks are unknown, that they have the option to accept or refuse the vaccine, and of any available alternatives to the product. Typically, this information is communicated in a patient “fact sheet.” The FDA posts these fact sheets on our website.
