What's happening

Hepatitis B Surface Antigen Hepatitis A Virus / Inactivated is currently affected by an active shortage report filed with Health Canada by GLAXOSMITHKLINE INC.

The reported cause is: delay in shipping of the drug. Manufacturers must report shortages, but end-date estimates are their own projections and often move.

If your usual product is affected, a pharmacist is the fastest route to a solution: they can dispense an unaffected manufacturer's equivalent when one exists, and in most provinces can adapt doses or substitute a therapeutic alternative without a new appointment.

Hepatitis B Surface Antigen Hepatitis A Virus / Inactivated is classified under “VIRAL VACCINES” (ATC J07BC).
