retro vaccination

[Prefix retro-, and Eng. vaccination.] Pathol.: The act of vaccinating a cow with lymph pa ed through a human body, or vaccinating a human subject with lymph derived from a cow which had been inoculated with vaccine matter from the human subject, or with lymph (from a human subject) that had been pa ed through the cow, retransferred to the human body, and taken again to the cow at the fifth, nineteenth, or other remove, as in the experiments of Ceely ( Seaton : Handbook of Vaccin .). Given goodl ymph, the result is as satisfactory as that obtained by ordinary vaccination, and, according to the German Commis sion on Vaccination, 1884-5. it would be impo ible to transmit syphilis from lymph obtained by any of the methods of retro vaccination. Animal lymph, on this ground chiefly, has been recommended by the German Government to supersede the use of human lymph.
