Designing global flu vaccines? Studies suggest common IGHD deletions may block key antibodies

MedicalXpress | mars 26, 2026

Inherited variations in antibody genes can affect how we respond to infections and vaccines, show two new studies from Karolinska Institutet published in the journal Immunity. The researchers have mapped immune gene variation across multiple global populations and shown how these variations affect the ability to form neutralizing antibodies, for example against the influenza virus.
