Summary

Story summary

Researchers developed an experimental vaccine that protects genetically modified mice from allergic reactions, including anaphylaxis, for up to a year by targeting immunoglobulin E (IgE).
In tests, unvaccinated mice died within 30 minutes of allergen exposure, and vaccinated mice showed only mild reactions.
The vaccine could provide longer protection than omalizumab and potentially benefit people with food allergies globally.
Clinical trials are needed to assess safety and efficacy in humans.
