Disclosed are compositions and methods for vaccinating susceptible individuals against infection by respiratory syncytial virus (RSV). The disclosed compositions include vaccine compositions comprising an effective amount of respiratory syncytial virus (RSV) F protein in a pre-fusion stabilized form and / or M protein incorporated into biodegradable polyanhydride polymer particles for inducing an immune response against RSV. The vaccine compositions also may include a suitable adjuvant.

The present invention relates to a process for preparing a crosslinked glycerol polyester, comprising a step of crosslinking a glycerol polyester with a cyclic carboxylic polyanhydride A in the presence of a metal triflate (or trifluoromethylsulfonate) compound, the cyclic carboxylic polyanhydride A comprising at least two cyclic carboxylic anhydride groups, the cyclic carboxylic polyanhydride A not comprising any linear carboxylic anhydride functions, and the metal of the metal triflate (or trifluoromethylsulfonate) compound being selected from the alkali and alkaline earth metals. The present invention also relates to a crosslinking composition useful for carrying out the process of the invention.
