For the first time since the battle
against the Human
Immunodeficiency Virus, HIV,
began, real hope has emerged of
prospects of long-lasting
immunity against the virus which causes Acquired Immune
Deficiency Syndrome, AIDS. This development arose from  a
scientifc feat by the Texas
Biomedical Research Institute on a
single dose novel HIV vaccine
designed to last a lifetime. Just last week, Texas Biomedical
Research Institute applied for a
patent for a genetically-
engineered vaccine strategy to
prevent HIV infection that targets
the outer layers of body structures that are the first sites of contact
with the virus. Statistics available have shown
that more than 90 percent of new
HIV infections worldwide are
transmitted by sexual intercourse
through outer layers of cells called
epithelial cells which line the surfaces of structures throughout
the body. The new vaccine is
directed to what the mucosal
layers of the epithelium in the
genital and rectal areas where the
virus enters the body. In Nigeria, populations at greatest
risk for HIV comprise 3.4 per cent
of population but account for up
to 40 percent of new infections. According to the researchers, the
newly developed vaccine would
lead to the continual production of
disease-fighting cells without
being eliminated by the immune
system. Another feature of the vaccine system is that it could be
adapted for use against other
infections. In the views of Marie-Claire
Gauduin, from Texas Biomed’s
Department of Virology and
Immunology, who is also a co-
inventor on the patent with
Philippe Blancou, a visiting scientist from the University of
Nice-Sophia Antipolis, France; “The
development of an effective AIDS
vaccine that restricts viral
replication at the mucosal level of
entry may be our best hope for controlling the HIV pandemic.” Gauduin added that only life-long
stimulation of the immune system
by the vaccine would be sufficient
to achieve long-term protection. One of the main reasons for the
failure of HIV vaccines thus far is
their inability to deliver antibody-
producing cells for prolonged
periods of time, thus only
achieving weak and transient protection at best. The primary target for viral
transmission through different
mucosal sites varies depending on
the tissue. However, soon after
crossing the mucosal layer, HIV
rapidly spreads to lymph nodes and other organs where it
replicates. The vaccine will have a molecule
and stem cell gene tagged to
target epithelial cells, that
combined, will promote the
production of antibody-producing
cells. Thus, the epithelial layer will continuously release new
antibody-producing cells and not
be eliminated by the body’s
immune response.
