Tetanus toxoid purified by antibody-affinity chromatography, was compared with conventionally purified material in a double-blind trial in 205 healthy blood donors. There was neither any difference in immunogenicity as assessed by enzyme-linked immunoassay nor in side-reactions between the two vaccines. This study confirms that side-reactions to tetanus toxoid are not eliminated by purifying it.
