US Military contributions to the global response to pandemic chikungunya

This experience provides lessons about epidemiological unpredictability, preparedness, vaccine manufacturing, the potential global importance of vaccine seed materials and the advisability of a global strategic plan. Consideration should be given to banking of vaccine production seeds, cell substrates, and manufacturing instructions. In view of the manufacturability, attenuation, and immunogenicity of Chikungunya Vaccine TSI-GSD-218, authorities may wish to consider this product as a possible candidate itself, as a comparator vaccine to improve upon, as a seed for inactivated vaccine, or as a source of virus or antigen for neutralization assays or immunoassays.
