Covid Vaccine

I have an appointment to get my first shot of the Covid vaccine tomorrow. I have an autoimmune disorder so my immune system is trash. I AM eligible (I’ve been getting pushback because I’m young). I’m just wondering for those of you that have already gotten it, did they require proof of your condition when you got the shot? I’m trying to find my paperwork but half of my stuff is still in boxes because this is a tiny apartment. Will the paperwork for my handicap placard suffice as proof?
