This is a real problem for people dependent on medicine.

My wife needs specific immuno-depressants to keep her alive (or at least not drastically decrease her health) and since we live in France it is not a problem.

When COVID hit I had real concerns about the manufacturing keeping up, but also about other mechanical devices she needs. These were at risk because they are manufactured in a normal factory (non-critical state infrastructure kind). Everything was fine but these are the moments you realize how reliant one is on technology, supply chain etc.
