Vaccines [1]

You may have questions about the compatibility of vaccines and breastfeeding. We encourage families to consult with their healthcare provider and any relevant Government guidance for information to help them make an informed decision regarding vaccination.

This post provides information about vaccines a nursing mother or parent may need, and some ways to comfort a baby who has received a vaccination.


For parents who may need vaccines during the course of the breastfeeding relationship, questions about which vaccines can be administered while maintaining breastfeeding can arise.  According to the American Academy of Pediatrics, “With rare exceptions, maternal immunization does not create any problems for breastfeeding infants[…][2]

Organizations such as The Infant Risk Center at Texas Tech University Health Sciences Center[3], MotherToBaby, a service of the Organization of Teratology Information Specialists[4], and The Breastfeeding Network[5] in the United Kingdom can provide information about specific substances and breastfeeding to share with your healthcare provider. The e-lactancia website offers information about medications in English and Spanish[6]

There are further resources in multiple languages in our article on Medications here.

The US based Center for Disease Control (CDC) has issued the guidelines linked here with regards to receiving vaccines while breastfeeding.

The CDC lists no precautions for breastfeeding with the following vaccines:

  • Immune globulins, pooled or hyper-immune
  • Diphtheria-Tetanus
  • Hepatitis B
  • Influenza Inactivated whole virus or subunit
  • Measles
  • Meningococcal meningitis
  • Mumps
  • Polio, inactivated

Many parents wonder about how to provide comfort for their breastfed baby receiving vaccines.  For the breastfed baby, the most comforting place in the world is close to you.  World Health Organization (WHO) recommends the following measures for comforting infants and young children before, during, and after receiving vaccines:

  • Infants and young children should be held by their caregiver
  • Caregivers should be present throughout and after the vaccination procedure
  • Infants should be breastfed during or shortly before the vaccination session, if it is culturally acceptable
  • Distractions such as toys, videos and music are recommended for children under 6 years of age[8]
