Does anyone know if taking clen while having a course of travel vaccinations will impair the vaccinations? I understand clen isn't a steroid (which do have immunosuppressive qualities and can prevent vaccinations working) but I can find little to no info on its interaction with vaccines. The only study I can find was on sheep, in which it did impair the production of antibodies and stop the vaccines working. I was hoping someone might have some more concrete advice. Thanks in advance.
