Study in mice shows K3-SPG can activate innate immunity, offering potential temporary defense against respiratory viruses while vaccines are developed.
Preparing for the emergence of new respiratory viruses is difficult because vaccines cannot be developed and deployed immediately after an outbreak begins. In a recent study, researchers from Japan found that a vaccine adjuvant called K3-SPG can provide mice with long-lasting, pathogen-independent protection against viruses like influenza A and SARS-CoV-2. The results underscore the potential for adjuvants to be stockpiled and deployed early during outbreaks while specific vaccines are being developed.

The researchers caution that these findings were demonstrated primarily in mice and do not establish that K3-SPG can protect people from respiratory viral infections. Further studies are needed to assess its safety, effectiveness, and suitability for human use, including differences in TLR9 biology and respiratory delivery.
