HP and Allergy: To check if parenteral Hp‐TGM could also control eosinophilia in this allergy model, we administered a pre‐mixed OVA/Alum solution intraperitoneally to mice at day 0, and recalled responses to OVA by administering it intranasally from day 7 to day 9 following injections with Hp‐TGM 3 h earlier on the same day.
