these science and technology investments to be able to translate products more effectively into the
advanced development process.
A. Broad Spectrum Products: Existing anti-infective products possess narrow activity across the
wide range of potential pathogens, a) Vaccines. Using Influenza as an example, vaccines are
exquisitely targeted such that a new influenza vaccine is required annually. Cross-protective vaccine
concepts offer the potential for a universal influenza vaccine, eliminating annual vaccines and
essentially providing pre-existing pandemic protection, b) Drugs. Given the virtually limitless
number of natural and potential organisms that could constitute public health threats, it is essential to
pursue the broad spectrum approach towards therapeutics. Truly broad spectrum products offer the
potential not only to address the vast, existing and emerging infectious disease spectrum, but to
produce effective countermeasures for 'unpredictable' diseases, c) Diagnostics. Highly multiplexed
methods that take advantage of the specificity in nucleic acid, antibody and other protein signatures
are well recognized as the approaches needed to develop rapid, sensitive and specific diagnostic
tools, but challenges lie in miniaturization, cost, computational analysis of multiplexed information
and signal to noise issues.
B. Broad Spectrum Platforms: The concept of new platforms pertains most readily to vaccines and
other biologics. Standardized recombinant DNA technologies must be developed for immediate
application in the context of emerging infectious diseases. Standardized methods offer the potential
to significantly reduce the complexity, time, and cost required to bring medical countermeasures to
general use. In addition, multiplexed platform diagnostics systems offer the capability to test for a
wide array of pathogens that are already recognized, while at the same time, offering a simple and
straightforward path for diagnosis as novel pathogens evolve or emerge.
C. Broad Spectrum Technology: Technological enhancements offer greater capabilities in storage,
dispersal, and utilization of countermeasures. NIH has focused on temperature stabilization and
alternative delivery for vaccines as ancillary technologies with potential applicability to existing as
well as future vaccines. This focus reflects the end-user needs for products that are less reliant on
cold chain, and can be self administered with a single dose. For example, temperature stabilization
allows for room temperature stockpiling which reduces storage and shipment costs as well as
extending the shelf life of the vaccine. The potential to improve the vaccination effectiveness in the
3rd world where cold chain capability can be limited is enormous.
2. ADVANCED DEVELOPMENT AND MANUFACTURING CAPABILITY
Successful efforts at the bench prove their worth in the advanced development stages of candidate
product development. Platform technologies must succeed against the increasing levels of
regulatory scrutiny during the scale up and testing process, and ultimately must produce a specific
vaccine, drug or diagnostic, and not just a general demonstration of technology feasibility.
Currently, challenges to advanced development include lack of product and manufacturing expertise
among innovative sponsors which are often small biotech companies, strong reliance on animal
models for efficacy data in lieu of trials in humans, insufficient methods to address safety and
discard those products likely to cause unacceptable toxicity in human trials, or to ensure product
reliability and stability, and lack of flexible capacity to surge or dampen manufacturing capacity
based on population and market needs. Early alignment of the biotechnology / innovator
