Does anyone out there, especially if they have had endocarditis, have any concerns about taking a TB test or even a flu shot for that matter? Inquiring mind wants to know because I want to volunteer at Tallahassee Memorial Healthcare and they require those immunizations. I was raised to be leary about these things. Scold me if you must but the TB bacteria has some sort of link to endocarditis. Thanks for any and all replies.
