Hepatitis B vaccine induces the production of antibodies against hepatitis surface antigen (anti-HBs) and prevents virus (HBV) infection. However, 5-10% individuals cannot develop anti-HBs even after multiple vaccinations (HB non-responders). We developed an intranasal containing both HBs (HBsAg) HB core (HBcAg) mixed it with a viscosity enhancer, carboxyl vinyl polymer (CVP-NASVAC). Here, we investigated prophylactic capacity CVP-NASVAC in non-responders. Thirty-four non-responders were...
