Assessment of the influenza vaccine (VAXIGRIP) in triggering a humoural immune response

Influenza vaccine triggered a humoural immune response to surface HA proteins in vaccinated subjects. To our knowledge, this is the first report corroborating the immunogenicity of the influenza vaccine in KSA volunteers. These results may be beneficial to the ministry of health and the Saudi FDA in terms of weighing the role of this vaccine in inducing protective immunity.
