Mmr vaccine and breastfeeding

Breastfeeding is a contraindication for smallpox vaccination of the mother because of the theoretical risk for contact transmission from mother to infant. Two serious adverse events have been reported in exclusively breastfed infants whose mothers were vaccinated with Yellow Fever vaccine. A study of mothers vaccinated with the Cendehill strain of live, attenuated rubella virus found no transmission of the live virus to their breastfed infants. Smallpox vaccine is contraindicated for use in breastfeeding mothers.

This is because live vaccinia virus can be inadvertently transmitted from a lactating mother to her infant through close contact transmission. Women of childbearing age who do not have evidence of immunity should get at least one dose of mmr vaccine.

It is safe for breastfeeding women to receive mmr vaccination. Breastfeeding does not interfere with the response to mmr vaccine , and the baby will not be affected by the vaccine through breast milk. Unfortunately, this type of passive immunity won’t keep your child from getting diseases like measles , pertussis, or the flu.

Possible Concerns With Breastfeeding and MMR 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 reported case of infant rubella possibly caused by the breastfeeding mother getting the MMR vaccine. Although breastfeeding passes many immune factors to baby , breastfeeding should not be considered a substitute for immunization. Research indicates that when breastfed babies are vaccinated , they will produce higher levels of antibodies in comparison to formula fed babies.

MMR vaccine is given later than some other childhood vaccines because antibodies transferred from the mother to the baby can provide some protection from disease and make the MMR vaccine less effective until about year of age. Learn about MMRV vaccine , which protects against measles, mumps, rubella, and varicella (chickenpox).

Both vaccine viruses have been transmitted to infants from breastfeeding mothers and caused adverse events. However, these vaccines are not routinely recommended to the general population in the United States. Many mothers have questions about the compatibility of vaccines and breastfeeding.

We encourage families to consult with their healthcare provider for information to help them make an informed decision regarding vaccination. Should my baby have the MMR vaccine? How often do adults need MMR shots? What are the dangers of the MMR vaccine?

The measles, mumps, rubella ( MMR ) viruses are alive but in a weakened or attenuated form. Smallpox and yellow fever are the two exceptions that are contraindicated for use in breastfeeding mothers. This means they can multiply in the body. The Centers for Disease Control and Prevention and the several health professional organizations state that vaccines given to a nursing mother do not affect the safety of breastfeeding for mothers or infants. A slightly higher percentage of infants who were breastfed during or after maternal vaccination with the active quadrivalent human.

This sheet talks about exposure to measles, mumps, rubella, and the MMR vaccine in pregnancy or while breastfeeding. This information should not take the place of medical care and advice from your health care provider. The majority of live viruses in vaccines have been shown to not transfer into human milk and do not pose a risk for mothers who are breastfeeding or for their infants.

Summary of Use during Lactation. Given the age indication for HZ vaccines (≥ yr), breastfeeding women are unlikely to be among the target population. Japanese encephalitis (JE) vaccine has not been studied in breastfeeding.

It is an inactivated vaccine and there is no theoretical reason to suspect increased risk of adverse effects in the mother or infants.

Flu vaccination is safe for breastfeeding women and their infants aged months and older. In fact, women who get the flu vaccine while pregnant or breastfeeding develop antibodies against flu that they can share with their infants through their breast milk.
