Question: if you were on a course of antibiotics could the bacteria become immune to it and it wouldn't work

Yes, and that’s a huge problem at the moment. Over the last few decades we’ve used so many antibiotics that there are now superbugs that are immune to them, which means we have nothing to kill them off. So there’s a lot of research at the moment being done to try and find new antibiotics which the bacteria aren’t immune to – although in years to come we’ll be in the same situation where bacteria are immune to the new antibiotics.
