Study Arms (3)

Neurotrauma

ACTIVE COMPARATOR

Patients with basilar skull fracture with or without known cerebrospinal fluid leakage were enrolled in the neurotrauma (NT) group. All patients were vaccinated with two vaccines at the same time, 0,5 ml PPSV23 and 0,5 ml Act-HIB which is a conjugate vaccine against H. influenzae type b.The vaccines were administered by subcutaneous injections within 10 days from trauma.

Biological: PPSV23, Act-HIB

Neurosurgery

ACTIVE COMPARATOR

Patients scheduled for elective, transsphenoidal pituitary gland surgery were assigned to the neurosurgery (NS) group. All patients were vaccinated with two vaccines at the same time, 0,5 ml PPSV23 and 0,5 ml Act-HIB which is a conjugate vaccine against H. influenzae type b.The vaccines were administered by subcutaneous injections within 10 days from surgery.

Biological: PPSV23, Act-HIB

Control

ACTIVE COMPARATOR

All control patients had undergone neurotrauma with or without basilar skull fracture, or had neurosurgery, at least three weeks earlier. All patients were vaccinated with two vaccines at the same time, 0,5 ml PPSV23 and 0,5 ml Act-HIB which is a conjugate vaccine against H. influenzae type b. They were vaccinated at least three weeks after trauma or surgery. The vaccines were administered by subcutaneous injections.

Biological: PPSV23, Act-HIB
