I tried to update today an earlier blog post but neither VIDI (started in 2012) nor VITALITY (started in 2014) posted or published any allergy result so far.
VITALITY seems to have some 2,681 participants under observation according to their study website while VIDI published only unrelated stuff about 801 participants.

According to an email yesterday, Vitality will publish primary outcome data in Q3 2024.
