Archaeal lipid adjuvants are synthesized by chemically coupling various carbohydrates or anionic polar groups to the free hydroxyl(s) of archaeal lipid cores. Chemically stable lipid cores such as saturated archaeol and caldarchaeol are obtained from appropriate Archaea. Archaeosome lipid vesicles are formulated from the synthetic lipids selected to serve as antigen carriers that target antigen-presenting cells and promote an appropriate immune response to the antigen.

The present invention is directed to absorbable polylactone copolymers prepared in part from about 2 to about 80 mole percent glycolide, utilizing a combination of a monofunctional polymerization initiator and a di-functional polymerization initiator, to achieve rates of crystallization of the copolymer of at least about 2 times faster than the rate of crystallization of a copolymer made by a similar process utilizing either the mono-functional or the di-functional polymerization initiator alone. Medical devices containing such copolymers are also disclosed.
