TOMATO-BASED RESPIRATORY SYNCYTIAL VIRUS VACCINE COMPOSITIONS

Fuente: WIPO "tomato"
The present disclosure relates to vaccine compositions against respiratory syncytial virus (RSV) that are tomato-based and their methods of production. The vaccine compositions comprise tomato fruit and plant-expressed fragment of RSV F protein, preferably the ectodomain of the RSV F protein. In some aspects, the vaccine compositions comprise tomato fruit and plant-expressed human immunodeficiency virus (HIV) virus-like particle (VLP) wherein the fragment of RSV F protein is displayed on the VLP surface. For example, the vaccine compositions are tomato paste spiked with the plant-expressed HIV VLP. In certain embodiments, the plant-expressed HIV VLP comprises a Gag protein; a fragment of gp41 protein, which comprises the C-terminal cytosolic domain of the gp41 protein; and a fragment of RSV F protein, wherein the fragment of RSV F protein lacks the p27 region and the C-terminus of the fragment of RSV F protein is linked to the N-terminus of the fragment of gp41 protein.
