Abstract

Influenza vaccines conferring immunity against multiple strains of virus will be developed at the VPP and manufactured through the VCMP for human clinical trials in compliance with current Good Manufacturing Practices (cGMP) and released for use in human clinical trials in healthy human volunteers. These vaccines may confer broad immunity, a "universal influenza vaccine," over a period of several years against multiple strains in contrast to seasonal products that are only useful for a single season. If these trials demonstrate safety and immunogenicity of these vaccines in human trials, further evaluation may take place in larger (Phase 2) trials which will necessitate production of the clinical trial materials (CTM) at larger scale. Such vaccines would be effective over multiple seasons and would require lengthy clinical study and monitoring for effectiveness across strains that vary from season to season. Vaccines under development include nanoparticle-based vaccines specific to certain influenza strains as well as more broadly applicable or universal influenza vaccines. Future vaccines will include multivalent nanoparticle approaches.
