Whats the view on the "morning after pill"
There's differing opinions within the hierarchy of the Catholic Church. It is universally condemned to use any method that stops the implantation of a fertilized egg (no different from abortion morally). But the debate comes over whether it actually does that or whether it stops fertilization from occurring. The former is never allowed, the latter can be allowed in extreme cases like rape.
In ordinary circumstances, it is a form of artificial contraception and isn't allowed any more than other forms because it perverts sex from it's intended purpose. But rape is already perverted so it's not a sin to try to defend yourself from the consequences of it, such as by using plan B or such. But once conception has occurred, the the unborn child has a right to life and it can't knowingly be terminated.
Here's some sources:
"Consequently, from the ethical standpoint the same absolute unlawfulness of abortifacient procedures also applies to distributing, prescribing and taking the
morning-after pill. All who, whether sharing the intention or not, directly co-operate with this procedure are also morally responsible for it."
Statement on the "morning-after pill'
"“A female who has been raped should be able to defend herself against a potential conception from the sexual assault. If after appropriate testing, there is no evidence that conception has occurred already, she may be treated with medications that would prevent ovulation, sperm capacitation, or fertilization. It is not permissible, however, to initiate or to recommend treatments that have as their purpose or direct effect the removal, destruction, or interference with the implantation of a fertilized ovum”."
The “Morning-After Pill”, Rape Victims and Ethical and Religious Directives for Catholic Health Care Services :: Catholic News Agency
"Germany’s Roman Catholic bishops have approved the use of the morning-after pill, but only under extreme circumstances. Church leaders made the decision after two rape victims were refused the pill at a Cologne hospital.
The bishops, meeting in the German city of Trier, agreed that Catholic hospitals in Germany should be allowed to prescribe the morning-after pill for women who had been the victims of rape.
However, Germany’s Catholic clergy stipulated that medicines may only be used that prevent conception and not as a means to induce abortion. The use of drugs that cause the death of an embryo or fetus would continue to be banned, even for rape victims, they said."
