My wife is one of the people at her hospital that explain this stuff at her Catholic hospital. It is my understanding that they provide this only in cases of rape (within the last 24 hours) and only after a pregnancy test to insure the victim is not pregnant when they roll in.
In the cases where they turn up preggers or they refuse the test, they send them along their way down the street to the public teaching hospital.
I know this probably would not “catch” a conceived egg before its attached. But the chances of that happening in the short window is very, very slim. I never say never, but it is very unlikely.
If you read the study, Dr. Kahlenborn’s point is that Plan B is largely ineffective, but when Plan B does work, the majority of the time it is via an abortifacient effect. Given the latter, it simply should not be used in Catholic institutions.
There’s a Catholic hospital in Vermont?
