I worked as a medical receptionist 17 years ago and we had to have all sorts of shots and tests as a requirement of employment. It was to protect patients and employees. I am phobic when it comes to needles, but, I needed the job. I cannot take anything with sulphur, but any others are fair game. That said, I now avoid them. But, I am not working there now, either.
But you knew that BEFORE you accepted the job, correct?
