Pregnancy: Pregnant women should not be vaccinated with ProQuad.
Studies have not been conducted with ProQuad in pregnant women. It is not known whether ProQuad can cause foetal harm when administered to a pregnant woman or affect reproduction capacity.
Pregnancy should be avoided for 1 month following vaccination. Women who intend to become pregnant should be advised to delay.
Breast‐feeding: Studies have shown that breast‐feeding postpartum women vaccinated with live attenuated rubella vaccine may secrete the virus in breast milk and transmit it to breast‐fed infants. In the infants with serological evidence of rubella infection, none had symptomatic disease. There is no evidence that varicella vaccine virus is excreted in breast milk. It is not known whether measles or mumps vaccine virus is secreted in human milk. Therefore, caution should be exercised when considering whether to administer ProQuad to a breast‐feeding woman.
Fertility: Animal reproduction studies have not been conducted with ProQuad. ProQuad has not been evaluated for potential to impair fertility.
