Afluria is approved to be given as both a normal shot (6 months+) and through a needle-free jet injector (ages 18-65).
Inactive ingredients:
Amounts are based on a 0.5 mL dose
Salts: help maintain the stability and pH of the vaccine
Preservatives: prevent bacterial growth and contamination
*Thimerosal is only in multi-dose vials of flu vaccines, which means that one vial of vaccine contains multiple doses. As a result, the container would be reused, so it needs a preservative to prevent contamination between the different uses from the same vial.
Antibiotics: used to prevent contamination during manufacturing
Carbohydrates: normally used as stabilizers in vaccines
