ProQuad and Breastfeeding
It is not known whether it is safe to receive ProQuad (MMRV) while breastfeeding. Research has shown that the virus in the rubella vaccine can pass through breast milk. However, it is unlikely to cause problems in most situations. Before receiving this vaccine while breastfeeding, talk to your healthcare provider about the potential risks.
ProQuad® (MMRV) is a vaccine used to prevent chickenpox, measles, mumps, and rubella. Although the Centers for Disease Control (CDC) and several other notable organizations state that almost all vaccines (including ProQuad) do not affect the safety of breastfeeding, there is some concern that breastfeeding women who receive the ProQuad vaccine might transmit the rubella virus to their infants.
The manufacturer states that this vaccine should not be given to women who are breastfeeding.
Research has demonstrated that the rubella vaccine virus can pass through breast milk. Although this is unlikely to cause problems in most situations, there has been one report of an infant getting rubella, which may have resulted from the breastfeeding mother receiving a rubella vaccine.
It is unknown whether the viruses in the measles and mumps vaccines pass through breast milk. Early studies suggest that the virus in the chickenpox vaccine probably does not pass through breast milk.
You should discuss breastfeeding and ProQuad with your healthcare provider. Each woman's situation is different, and you and your healthcare provider understand your situation best. After considering what you want and expect, as well as your current health situation, the two of you can make a shared decision that is right for you.
