Full clinical immunizations required for a 100% remote role

I’m really just venting here. I am going through the onboarding process for a 100% remote role for an employer in another state. They require a long list of immunization records. If I cannot locate them I have to go to two different labs to get blood tests. My mom is dead and I don’t remember who my dr was when I received my childhood immunizations. They told me I only have 48 hours to locate them or go get the blood tests. I emailed my state for the records but I dont even know if I will receive a reply with in 48 hours. I’m just annoyed and venting. I think this is pretty over the top and has really put a damper on my experience with this new employer.
