Generex's New Vaccine Technology Could Speed Flu Vaccine Availability

WORCESTER, Mass., June 26, 2009 (GLOBE NEWSWIRE) -- Antigen Express Inc., a
wholly owned subsidiary of Generex Biotechnology Corporation (Nasdaq:GNBT), has
developed new vaccine technology that "could rapidly lead to safe, effective flu
vaccines," according to a June 23, 2009 article in the Worcester, Massachusetts
Telegram & Gazette.

"It's not a biological process, it's a chemical process," explained Douglas M.
Powell, PhD, director of immunobiology at Antigen Express. "It's not futuristic,
it's here now."

The article notes that in contrast with traditional vaccines, which require
literally cracking millions of hen eggs, Antigen Express uses lab equipment to
string together amino acids into peptides that can stimulate the body to produce
immune cells in response to specific threats, such as influenza.

"If Antigen Express could develop an H1N1 vaccine, large-scale production could
take place rapidly in existing facilities," Dr. Powell said. "The capacity
exists now that you could literally make billions of doses of this vaccine."

Earlier this month, Generex announced positive results of a recently completed
Phase I trial of its prostate cancer vaccine. The immunotherapeutic peptide AE37
is also being developed by Antigen Express for multiple cancer indications.

introductory words such as "expects," "plans," "intends," "believes," "will,"

fact that they do not relate strictly to historical or current facts.
Forward-looking statements frequently are used in discussing potential product

Many factors may cause actual results to differ from forward-looking statements,

some of which are known and others of which are not. Known risks and
uncertainties include those identified from time to time in the reports filed by
Generex with the Securities and Exchange Commission, which should be considered

guarantee of future results or events, and one should avoid placing undue
reliance on such statements. Generex undertakes no obligation to update publicly
any forward-looking statements, whether as a result of new information, future
events or otherwise. Generex cannot be sure when or if it will be permitted by
regulatory agencies to undertake additional clinical trials or to commence any
particular phase of clinical trials. Because of this, statements regarding the
expected timing of clinical trials cannot be regarded as actual predictions of
when Generex will obtain regulatory approval for any "phase" of clinical trials.
Generex claims the protection of the safe harbor for forward-looking statements
that is contained in the Private Securities Litigation Reform Act.
