The present disclosure is directed to capsid assembly inhibitor compositions and methods for use in the treatment of hepatitis B virus infection.

Stable lyophilized immunogenic compositions include inter alia live attenuated recombinant flaviviruses, more preferably live attenuated recombinant dengue viruses, at least one carbohydrate, at least one amino acid and is particularly amenable to rapid freeze-drying treatments wherein, the composition preserves desired characteristics of a virus, including virus viability, immunogenicity and stability. The immunogenic composition is devoid of preservatives, polymers and surfactants. The methods for manufacturing the stable lyophilized immunogenic compositions are also provided.

The invention provides a method and a kit for combined virus inactivation and capture/purification of a feed containing a protein of interest. The method comprises the steps of: contacting a feed comprising a protein of interest with negatively charged particles or media, conditioning the particles or media such that the pH is acidic thereby inactivating said virus, and eluting said protein of interest.
