Backpedaling on globalization doesn't necessarily have to mean going back to no globalization. It just means now being away for the drawbacks and accounting for them. No every country doesn't need to produce their own medical equipment, but enough will that consider it important to do so and have the internal demand to support it and that will create supply-chain optionality for those that don't produce their own supplies.
Every country that doesn't manufacturer their own equipment and supplies will be far better off when they have several countries they can source from.
