Vectored Immunoprophylaxis for Mucosal Immunity: Advances and Challenges Associated with Recombinant Secretory IgA Expression.
Review in Vaccines, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Existing vectored immunoprophylaxis (VIP) approaches have primarily focused on IgG, which provides systemic protection but is less specialized in mucosal immunity. In contrast, secretory IgA (sIgA) plays a central role at epithelial surfaces, promoting pathogen neutralization while limiting inflammation. Although monoclonal IgA therapies are effective, their short half-life requires repeated dosing. Thus, VIP strategies enabling sustained sIgA expression at mucosal sites could transform mucosal infection prevention and treatment. This review outlines the key challenges associated with in vivo IgA expression and discusses critical considerations for VIP-mediated IgA delivery at mucosal surfaces, with emphasis on its potential for clinical translation. We provide a detailed overview of platforms for targeted IgA expression, including adeno-associated virus (AAV), adenoviral and lentiviral vectors, and lipid nanoparticle-based systems, alongside relevant routes of administration. Additionally, we examine emerging strategies to enhance the robustness, durability, and localization of IgA expression in vivo. Overall, VIP-enabled IgA expression represents an emerging strategy for enhancing mucosal immunity, with continued advances required to establish its role in the prevention and treatment of mucosal infections.
