Type I interferon inducers may potentially be engineered to function as antiviral and anticancer agents, or alternatively, vaccine adjuvants, all of which may have clinical applications. We recently described a simple strategy to convert a Toll-like receptor 9 (TLR9) agonist devoid of interferon α (IFNα) stimulating activity into a robust Type I interferon inducer with potent vaccine adjuvant activity.

Porcine reproductive and respiratory syndrome (PRRS), caused by the highly variable PRRS virus (PRRSV), presents a significant challenge to the swine industry due to its pathogenic and economic burden. The virus evades host immune responses, particularly interferon (IFN) signaling, through various viral mechanisms. Traditional vaccines have shown variable efficacy in the field, prompting the exploration of novel vaccination strategies.

The emergence of mRNA vaccines offers great promise and a potent platform in combating various diseases, notably COVID-19. Nevertheless, challenges such as inherent instability and potential side effects of current delivery systems underscore the critical need for the advancement of stable, safe, and efficacious mRNA vaccines. In this study, a robust mRNA vaccine (cmRNA-1130) eliciting potent immune activation has been developed from a biodegradable lipid with eight ester bonds in the branched tail (AX4) and synthetic circular mRNA (cmRNA) encoding the trimeric Delta receptor binding domain of the SARS-CoV-2 spike protein.

Continuously emerging SARS-CoV-2 Omicron subvariants pose a threat thwarting the effectiveness of approved COVID-19 vaccines. Especially, the protection breadth and degree of these vaccines against antigenically distant Omicron subvariants is unclear. Here, we report the immunogenicity and efficacy of a bivalent mRNA vaccine, PTX-COVID19-M1.

Malaria remains the fifth deadliest parasitic infection worldwide, despite significant advancements in technology. A major challenge in combating this disease lies in the growing resistance of malaria parasites to antimalarial drugs and insect vectors to insecticides. The emerging inefficacy of artemisinin-based combination therapies (ACTs) further exacerbates the issue.

Transmission-blocking vaccines (TBVs) targeting sexual-stage antigens represent a critical tool for malaria control and elimination through inhibiting parasite development within mosquitoes. P230, displayed on the surface of gametocytes and gametes, plays a crucial role in gamete fertilization and is one of the leading TBV candidates for both Plasmodium falciparum and P. vivax.
