CNJ-016- human vaccinia virus immune globulin injection
Emergent BioSolutions Canada Inc.


Blood glucose measurement in patients receiving VIGIV must be done with a glucose-specific method (monitor and test strips) to avoid interference by maltose contained in VIGIV. Glucose dehydrogenase pyrroloquinolinequinone (GDH-PQQ) or glucose-dye-oxidoreductase method (monitor and test strips) must not be used for blood glucose testing in patients receiving VIGIV, since maltose in IGIV products has been shown to give falsely high blood glucose levels in these testing systems. This could result in the inappropriate administration of insulin, resulting in life-threatening hypoglycemia. Cases of true hypoglycemia may go untreated if the hypoglycemic state is masked by falsely elevated glucose readings.

Carefully review the product information of the blood glucose testing system, including that of the test strips, to determine if the system is appropriate for use with maltose-containing parenteral products [see 5.3 Blood Glucose Monitoring ].


VIGIV (vaccinia immune globulin intravenous, human) is indicated for the treatment and/or modification of the following conditions:

Eczema vaccinatum
Progressive vaccinia
Severe generalized vaccinia
Vaccinia infections in individuals who have skin conditions such as burns, impetigo, varicella-zoster, or poison ivy; or in individuals who have eczematous skin lesions because of either the activity or extensiveness of such lesions
Aberrant infections induced by vaccinia virus that include its accidental implantation in eyes (except in cases of isolated keratitis), mouth, or other areas where vaccinia infection would constitute a special hazard.

VIGIV is not considered to be effective in the treatment of postvaccinial encephalitis.


For intravenous use only.

2.1 Dosage for Treatment of Severe Complications of Vaccinia Vaccination

Administer VIGIV at a dose of 6000 Units per kg, as soon as symptoms appear and are judged to be due to severe vaccinia-related complication. Consider repeat dosing, depending on the severity of the symptoms and response to treatment; however, clinical data on repeat doses are lacking. Consider higher doses (e.g. 9000 Units per kg) if the patient does not respond to the initial 6000 Units per kg dose. Doses up to 24,000 Units per kg administered to healthy volunteers were well tolerated in clinical trials [see 14 CLINICAL STUDIES].

2.2 Preparation

Bring VIGIV vials to room temperature prior to dosing.
If frozen, thaw vial by placing in a refrigerator at 36 to 46°F (2 to 8°C) until the contents are thawed for approximately 14 hours. Product can be thawed rapidly by placing at room temperature for one hour followed by a water bath at 98.6°F (37°C) until thawed.
Do not thaw this product in a microwave oven.
Do not refreeze the vial.
Remove the entire contents of the vial to obtain the labeled dosage of VIGIV. If partial vials are required for the dosage calculation, withdraw the entire contents of the vial to ensure accurate calculation of the dosage requirement.
VIGIV is compatible with 0.9% Sodium Chloride USP. No other drug interactions or compatibilities have been evaluated. If a pre-existing catheter must be used, flush the line with 0.9% Sodium Chloride USP before use. VIGIV may be administered either undiluted or diluted no more than 1:2 (v/v).
VIGIV vial is for single use only. Do not reuse or save VIGIV for future use.
VIGIV contains no preservatives. Discard partially used vials.

2.3 Administration

Inspect the product prior to use and do not use if solution is cloudy, discolored or contains particulates.
Administer VIGIV intravenously through a dedicated intravenous line with the rate of infusion of no greater than 2 mL/min.
For patients weighing less than 50 kg, infuse the product at a rate no greater than 0.04 mL/kg/minute (133.3 Units per kg/minute).
Adverse drug reactions may be related to the rate of infusion. Slower infusion rate may be needed for patients who develop a minor adverse reaction (e.g. flushing) or for patients with risk factors for thrombosis/thromboembolism.
Closely monitor and carefully observe patients and their vital signs for any symptoms throughout the infusion period and immediately following an infusion.
For patients with pre-existing renal insufficiency, or at increased risk of acute kidney injury, thrombosis, or volume overload, do not exceed the recommended infusion rate and follow the infusion schedule closely.
For patients with risk factors for thrombosis, the maximum daily dose of VIGIV should not exceed 12,000 Units per kg [see 5.4 Thrombosis]


Solution of gamma globulin (5% or 50 mg/mL)
20 mL single-dose vial containing antibodies to vaccinia virus at ≥50,000 Units per vial


VIGIV is contraindicated in:

Isolated vaccinia keratitis.
Individuals with a history of anaphylaxis or prior severe systemic reaction associated with the parenteral administration of this or other human immune globulin preparations.
IgA-deficient patients with antibodies against IgA and a history of IgA hypersensitivity, as it contains trace amounts of IgA (40 mcg/mL).


5.1 Hypersensitivity

Severe immediate hypersensitivity reactions to plasma-derived products may occur, for example, in patients with IgA deficiency or hypersensitivity to human globulin. Although acute systemic allergic reactions were not seen in clinical trials with VIGIV [see 6.1 Clinical Trials Experience], administer the product only in a setting where appropriate equipment and personnel trained in the management of acute anaphylaxis are available. In case of hypotension, allergic or anaphylactic reaction, discontinue the administration of VIGIV immediately and give supportive care as needed. In case of shock, observe the current medical standards for shock treatment.

5.2 Acute Renal Dysfunction/Failure

Renal dysfunction, acute renal failure, osmotic nephropathy, proximal tubular nephropathy, and death may occur upon use of immune globulin intravenous (Human) (IGIV) products. Use VIGIV with caution in patients with pre-existing renal insufficiency and in patients at risk of developing renal insufficiency (including, but not limited to those with diabetes mellitus, age greater than 65 years, volume depletion, paraproteinemia, sepsis, and patients receiving known nephrotoxic drugs), and administer VIGIV at the minimum rate of infusion practicable. In these cases, it is important to ensure that patients are not volume depleted before VIGIV infusion. Do not exceed the recommended infusion rate and follow the infusion schedule closely [see 2.3 Administration]. Periodic monitoring of renal function and urine output is particularly important in patients judged to be at increased risk of developing acute renal failure. Assess renal function, including measurement of blood urea nitrogen (BUN) and serum creatinine, before the initial infusion of VIGIV and at appropriate intervals thereafter. If renal function deteriorates, consider discontinuing VIGIV.

Most cases of renal insufficiency following administration of IGIV have occurred in patients receiving total doses containing 400 mg/kg of sucrose or greater. VIGIV does not contain sucrose. No prospective data are currently available in patients with risk factors for renal insufficiency to identify a maximum safe dose, concentration, and/or rate of infusion for VIGIV.
