Hold on, are you saying that antibiotics don’t protect from infection?
I'm saying that antibiotics are not 100% protection, partly because there are several types of antibiotics, each working best on a particular microorganism, so it's possible that she becomes infected with a bacteria that is not affected by the particular antibiotic she's taking. Also, it's possible that she is infected with such a large dose of bacteria that the antibiotics are not able to neutralize them all. Also, due to overuse of antibiotics, some bacteria have become resistant to them. The fact that she developed the specific infection she did is not evidence that she didn't take antibiotics.
Did this woman receive antibiotics? No!
We don't know that, since we don't have her entire medical history.
There are other things doctors do to ward off infection under expectant care management as well FWIU. So how can you say “there is no reason to think she wouldn’t off gotten the infection in the hospital”?
There are other things doctors can do in the hospital for certain women with difficult pregnancies, depending on the particularities of each case.
In the case in Ireland the law necessitated a higher level of progression into the infection, no?
Wikipedia, two different parts of the article:
Irish law at that time forbade abortion if a
fetal heartbeat was still present.
The law in force at the time stated that the act of abortion, where there was no
immediate physiological threat to the woman's life to continue the pregnancy, was a criminal offence punishable by life imprisonment.
