Theory of Neo-Springerism

Better differentiated cancers (least aggressive) are said to produce a greater amount of antigen T, while the least differentiated cancers (most aggressive) produce the greatest amount of antigen Tn.

Springer's Vaccine

Springer's vaccine consisted of three parts:

  • Chemically degraded O-group blood cells (providing T and Tn antigens)
  • Salmonella typhii vaccine or typhoid vaccine (which contains T and Tn antigens)
  • Calcium phosphate (he believed the T and Tn antigens could stick to this).
