Here is some information from the U.S. Conference of Catholic Bishops about a Catholic moral perspective on Covid vaccines.  I would like to call your attention in particular to the fact that while it is permissible for Catholics to receive the vaccines, we also have a responsibility to protest the use of cell lines derived from aborted babies. The Missouri Catholic Conference has sample letters that can easily be printed, signed, and sent to the various vaccine companies.  If you have not done so, please take some time to share this feedback with these companies. You will find sample letters here: https://mocatholic.org/resources/covid-19-resources.
