I live in the countryside. During winters (starting about this time of the year), the roads here are barely usable under normal conditions. We occasionally end up not being able to get to the store for two or three days due to heavy snowfall. We also have occasional power outages caused by heavy snowfall.

I'd say it's only a matter of time before we're hit by a severe blizzard and we need to manage on our own for a week or two. We do have antibiotics and other basic medical supplies at home, for such occasions. We also keep enough food and firewood for at least two weeks, sometimes more.

As for making one's own antibiotics, one of the most commonly repeated survivalist mantras is that one should always have and maintain a skill that will be useful in order to rebuild, in case society collapses. That way, if we do end up with zombies roaming the streets, Illuminati death squads chasing survivors, and a runaway AI trying to exterminate humanity, you will have something to offer the groups trying to rebuild.

Personally, I know how to make booze. My neighbors do, indeed, seem to appreciate that skill. :D
