Pregnancy: Pregnancy Category C: Animal reproduction studies have not been conducted with refrigerator-stable VARIVAX. It is also not known whether refrigerator-stable VARIVAX can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Therefore, refrigerator-stable VARIVAX should not be administered to pregnant females; furthermore, pregnancy should be avoided for three months following vaccination (see Contraindications).
Nursing Mothers: It is not known whether varicella vaccine virus is secreted in human milk. Therefore, because some viruses are secreted in human milk, caution should be exercised if refrigerator-stable VARIVAX is administered to a nursing woman. (See Transmission under Precautions.)
