FDA carefully evaluates the safety and effectiveness of vaccines, both before and after they reach the market. These evaluations, which are done in both "test tube" studies as well as in animal models, are often labor- intensive and time-consuming.
Our laboratory is adapting cutting-edge tools of biotechnology to make the design and evaluation of new vaccines more efficient. We will use these technologies to get more detailed knowledge of the structure and properties of vaccines. Such knowledge will help to improve the design and manufacture of vaccines, making them significantly safer and more effective.
The design and manufacturing of vaccines is done mainly by the vaccine industry, and to a lesser extent by academic researchers. However, FDA scientists can lead and coordinate this work, making the results publicly available to the entire industry and general public. This will maximize the efficiency of these efforts and thus facilitate FDA regulatory evaluation of these products, reducing the time needed to approve vaccines and make them available to the public.
Our research program focuses on creating, validating, and using new biotechnology tools for in-depth studies of the molecular makeup of vaccines and for studying how people respond to vaccines. We base our approach to this research on the concept of molecular consistency; that is, on ensuring that manufacture of vaccines results in products that are uniform in their molecular makeup. Using this approach, FDA regulators will work to ensure that vaccines conform to the highest standards of quality, based on their molecular consistency.
The program is pursuing several strategies to achieve this goal: 1) analyzing how likely it is that vaccines made from live viruses will undergo gene mutations that degrade their safety and effectiveness; 2) determining which molecular parts of the vaccines are responsible for triggering immune system responses and studying in detail those immune system responses; and 3) creating new ways to evaluate both the inactive components of vaccines used to increase vaccine potency (e.g. adjuvants) and ways to prevent or mitigate adverse reactions caused by those components.
Since animal testing is likely to remain the gold standard for many products, this program seeks to improve this technique by using genetically modified mice. We are also trying to incorporate new imaging techniques and other technologies to study the effect of vaccines on these mice. Our aim is to reduce the number of animals that must be used while significantly increasing the amount and precision of scientific information produced by these studies.
We are analyzing the molecular consistency of vaccines in a variety of ways. First, we monitor the genetic stability of live viral vaccines through sensitive analysis of their genetic composition. This approach is based on the quasi-species concept that natural viral populations (including stocks of live viral vaccines) contain a wide variety of mutants. Even though most such mutants are present at a very low level, together they can significantly affect biological properties of vaccines. Therefore, one of our objectives is to create methods for characterizing and quantifying small quantities of mutants that have potentially deleterious properties. The techniques developed to monitor genomic consistency of vaccines can also be used to investigate cases of vaccine-induced adverse reactions.
A second strategy we are pursuing to analyze molecular consistency of vaccines is the development of new methods for detailed characterization of the immunochemical properties of vaccines and the immune responses to them. This includes creating ways to determine the repertoire of epitopes (epitope profiles) that inactivated vaccines contain, and analyzing the repertoire of antibodies (paratope profiles) in sera of vaccine recipients.
We are also pursuing immunological characterization of new vaccine products by developing novel immunization-challenge methods using transgenic mouse models. This is especially important in the case of poliovirus vaccines, for which the only natural model are primates. Specifically, we use transgenic mice susceptible to poliomyelitis to compare the efficacy of different products containing inactivated poliovirus vaccine. The program also aims to analyze results of clinical trials of new vaccines, including studies in special populations, such as premature infants. We are also developing new methods to analyze clinical samples that improve the power of vaccine clinical trials.
In addition, our program is studying certain adverse reactions caused by oral polio vaccine (OPV) that require treatment. OPV can trigger emergence of circulating vaccine-derived polioviruses (cVDPV) and can also establish persistent infections in immunocompromised individuals who subsequently excrete vaccine derived viruses (VDPV). One of the objectives of this program is to create ways to assess the efficacy of methods designed to mitigate adverse consequences of OPV vaccination. We use methods based on transgenic mouse models to assess the efficacy of anti-poliovirus drugs and human monoclonal antibodies proposed for treating chronically infected individuals, and to stop outbreaks caused by VDPV.
Finally, since new vaccines increasingly contain adjuvants added to improve their efficacy and modify the immune response, we are developing new methods for preclinical and clinical evaluation of vaccines containing adjuvants. Our goal is to be able to analyze the consistency of adjuvanted vaccines using cutting-edge molecular approaches such as in vivo models of human immune system (MIMIC®), and to use the FACTORIAL® protocol to analyze the activity of cellular signal transduction pathways (transcription factors activity profiles).
