There are more and more accommodations for physical disabilities where a medical intervention is readily available, such as glasses. There are still lots of barriers, but it is often seen as a moral right to make things easier for them, especially if it’s in such a way that they can maintain their autonomy.
I have ASD and ADHD, and in many societies, there is still a big lack of understanding. People could try being accommodating, but they don’t have enough practice with that that it ends up being very, very hard/exhausting to do it even partially.
Compare how it’s done in Europe: Vaccinations happen in vaccination centres, and your status as well as the vaccine details (lot number etc) get registered with the government. Each country has an app that generates a QR code that is common throughout the EU, and restaurants etc can check it in places which require a vaccine passport. I’m more inclined to trust those than some random cards which are often handwritten!
