"It is morally permissible to receive the vaccines developed by Pfizer and Moderna. Neither of these vaccines have used cell lines originating in tissue taken from aborted babies in their design, development, and production.

This connection to the abortion is very remote, however, and it is important to keep in mind that there are varying levels of responsibility. Greater moral responsibility lies with the researchers than with those who receive the vaccine.
