aIIV-B

aIIV-B stands for "adjuvanted inactivated influenza vaccine, quadrivalent, B strain." It is not an individual pharmaceutical drug but rather refers to a specific formulation of the influenza vaccine. The "a" denotes that it is adjuvanted (contains an immune-boosting substance), "IIV" means inactivated influenza vaccine (the virus is killed and cannot cause disease), and "B" indicates that it targets the Influenza B virus strains. This type of vaccine is used primarily for seasonal flu prevention, especially in populations at higher risk such as older adults. The adjuvant enhances the immune response to the viral antigens present in the vaccine.
