How were transfer factors discovered? 

In 1949, Dr. H. Sherwood Lawrence, distinguished immunologist at New York University, determined that an immune response could be transferred from a donor to a recipient through a white blood cell extract. He concluded that the extract contained a factor capable of transferring the donor’s immunity information to the recipient and named the substance transfer factor.

Is there scientific validation for Transfer Factors and Nanofractions? 

Yes. In the 50 years since Dr. Lawrence’s pioneering work on Transfer Factors, an estimated $40 million has been spent researching Transfer Factors and hundreds of scientific papers have been published documenting their effectiveness.
