Not Merry, but I have found some reports in VAERS, the reaction reporting system, so as a part of the decision structure, the reports will be reviewed and evaluated before full, permanent approval by FDA. It is possible that, in the future, one vaccine may be recommended over others for people with specific underlying conditions.

All of this makes it very important that everyone report their adverse reactions in VAERS: https://vaers.hhs.gov/reportevent.html There is no guarantee that events reported here or to your physician make it into the system.
