Public Release: 

Single-administration polio vaccine

Proceedings of the National Academy of Sciences

Researchers developed a single-administration vaccine strategy for polio using an injectable microsphere bearing inactivated polio vaccine (IPV) that releases stable antigen over time; the researchers used biocompatible excipients to stabilize IPV, and found that injecting the microspheres into rats elicited a strong immune response against all three IPV antigens.
