  • Publication number: 20230115214
    Abstract: Described herein is the use of thin film freeze drying methods with oil-in-water adjuvants to produce improved vaccine compositions. This approach solves several major problems associated with the emulsion-adjuvanted vaccines. Additionally, the developed dry powder compositions have the potential to be administered via non-invasive routes (such as intranasal, pulmonary, transcutaneous with or without microneedles) and be stored at ambient temperatures which significantly reduce the costs of vaccination programs.
