| In the late 1940s while studying
tuberculosis, Dr. H. Sherwood Lawrence determined that a
substance in an extract from leukocytes (white blood cells)
taken from an individual recovered from tuberculosis could
transfer a positive immune response to tuberculosis to a
recipient who had not yet been infected. He named the
substance transfer factor. Shortly after Dr. Lawrence’s
findings, researchers realized that animals provide an
effective and economical source of transfer factor
molecules. And despite transfer factors taking a subordinate
role to “the miracle” of antibiotics, researchers have
conducted numerous studies to explore the safety and
effectiveness of transfer factor, and hundred of papers have
been published that document the benefits of transfer factor
for overall immune health as well as a target against
specific illnesses.
Today, several manufacturers offer transfer factors in
supplement form ranging from dried whole colostrum to
concentrated transfer factor extracts. Transfer factors that
have been extracted and concentrated provide a more potent
supplement form. Some manufactures further combine transfer
factors with additional ingredients thought to benefit the
immune response.

Dr. Lawrence discovered
that immunity information can be transferred safely
between humans. Thereafter, hundreds of research studies
have been made to prove the safety and effectiveness of
transfer factor from animal sources for overall human
immune health as well as a target against specific
illnesses. |

Dr.
H. Sherwood Lawrence graduated from the NYU School of Medicine in 1943.
From 1943 to 1949, he served as a medical intern and then as
a medical officer with the U.S. Navy, seeing activity in
southern France and Japan and receiving two Bronze Stars. He
served on the faculty of the NYU School of Medicine from
1947 to 1959 and from 1959 until his retirement in 2000, was
head of infectious diseases and immunology at NYU. He also
served as co-director of medical services at Bellevue and
New York University hospitals from 1964 to 2000, director of
the NYU cancer center from 1974 to 1979 and director of the
NYU AIDS research center from 1989 to 1994. He was a member
of the National Academy of Sciences and honorary chairman of
the International Transfer Factor Society (ITFS), a
scholarly organization committed to the worldwide exchange
of information pertaining to the immunologic properties of
leukocyte dialysates. The knowledge of transfer factors
owes its existence to immunology pioneer Dr. Lawrence. In 1949, Lawrence discovered that by injecting an
extract from the leukocytes of someone previously infected
with tuberculosis into someone as of yet uninfected with it,
immunity was conferred to the recipient, sparing him/her
from developing the infection. Dr. Lawrence named the
extract transfer factor and the possibility of sharing
natural immunity between people and even animals and people
became real.
