Is taking a tb shot safe with a hypertension medication?

I'd like to volunteer at the hospital and one of the requirements is the tb shot? Specifically, I am worried about the reaction with a hypertension medication I am taking. I also have this paranoia because two of my aunts (twins) died in infancy after the Nazis injected them with some kind of antiviral medication. The Nazis said they weren't supposed to eat high Vitamin C foods. This raises some questions, should I follow some kind of a dietary restriction if I choose to have the tb shot?
