What groups of patients are eligible for VariZIG? VariZIG is recommended for patients without evidence of immunity to varicella who are at high risk for severe varicella and complications, who have been exposed to varicella or herpes zoster, and for whom varicella vaccine is contraindicated. What is the recommended dosage of VariZIG?

VariZIG is supplied in IU vials and should be administered intramuscularly as directed by the manufacturer. The minimum dose is For ordering information see varizig. A one-month-old infant was exposed for the last 6 days to chickenpox. What should be done to protect the exposed infant, who is too young to vaccinate? There is no evidence that healthy full-term infants born to women in whom varicella occurs more than 48 hours after delivery are at increased risk for serious complications such as pneumonia or death.

Varicella zoster immune globulin, VariZIG, can be given up to 10 days after exposure but is only recommended for newborn infants whose mothers have signs and symptoms of varicella around the time of delivery 5 days before to 2 days after , hospitalized premature infants born at 28 or more weeks of gestation whose mothers do not have evidence of immunity to varicella, or hospitalized premature infants born at less than 28 weeks of gestation or who weigh 1, grams or less at birth regardless of their mothers' evidence of immunity to varicella.

Assuming this is an infant at home, VariZIG would not be recommended. Varicella, if it develops, would be managed as for any child. Storage and Handling Back to top How should varicella vaccine be stored in my clinic?

These vaccines can deteriorate rapidly after they are removed from the freezer. A stand-alone storage unit that is frost-free or has an automatic defrost cycle is preferred. Frozen vaccines should not be stored in the freezer compartment of a combination unit because household freezers cannot maintain proper storage temperatures for frozen vaccines.

This applies to both temporary and long-term storage of frozen vaccines. The diluents should be kept separately in the refrigerator or at room temperature. Live varicella-containing vaccines must be administered within 30 minutes of reconstitution. What happens if you put varicella vaccine in the refrigerator instead of the freezer? Vaccine will be damaged if not stored according to the manufacturer's instructions. However, it may still be possible to use vaccine that has not been properly stored.

Put the affected vaccine vials into the freezer after you have marked them so they are not confused with the unaffected vials, then call the manufacturer at VARIVAX for further guidance about whether the vaccine is still usable. Unreconstituted varicella vaccine may be stored in the refrigerator for up to 72 hours before use. If refrigerated varicella vaccine is not used within 72 hours, it should be discarded. If you have inadvertently left your vaccine at room temperature instead of in the freezer or have experienced a power failure, label the affected vaccine to keep it separated from unaffected vaccine and return it to recommended storage conditions in a freezer promptly, then contact the manufacturer for further guidance.

Do not administer the vaccine until you have consulted with Merck. How can I transport varicella vaccine? What if I do not have access to a portable freezer? The vaccine manufacturer does not recommend transporting varicella-containing vaccines varicella, MMRV. Do not use dry ice, even for temporary storage.

Any stand-alone freezer that maintains these temperatures is acceptable. I was told by a coworker that varicella vaccine can be stored at refrigerator temperature for up to three days and still be used.
