Doctor Called About My Labs

I got all my bloodwork & genetic testing done last Friday. I’m 11w2d today. Yesterday they called to let me know that everything came back normal except that I’m not immune to (long word that starts with an “a”) and to stay away from anyone who has chicken pox or shingles. I’m fully vaccinated (to my knowledge) and this never showed up in my bloodwork in my previous pregnancies. Maybe they just never tested for it? Idk…still waiting for the genetic testing results to come back. Has anyone else found this out after being fully vaccinated? They said I can’t even get the vaccine until after I have the baby.
