A lot of H1N1 and flu vaccines has been recalled after cracks in the vials of vaccine were discovered. This has caused some vials to break in addition to being a contamination risk.

Anyone who was vaccinated in the week before December 17, 2010 with batch number 111812P1 made by Novartis Vaccines and Diagnostics, Inc, should make an appointment for a clinical assessment.

Anyone previously vaccinated with a dose from this lot who did not experience side-effects should be unaffected and no further action is required.
