Vaccine produces DIY Xolair-like antibody, protects against anaphylaxis

In their paper, which they published in Science Translational Medicine on Dec. 3, 2025, the authors noted that the polyclonal antibodies generated by their vaccine lasted “for up to 12 months postvaccination with a similar avidity as the approved anti-IgE mAb omalizumab [Xolair, Roche AG].”
