Vaccines have low bio-availability and absorption from breastmilk is unlikely in most circumstances other than with live vaccines. Cessation or interruption of breastfeeding is not normally required but individual regimens should be considered especially with yellow fever (Data taken from LactMed website [2012]; Martindale [2005]; Advisory Committee on Immunization Practices [ACIP]; CDC [Kroger 2006]; Advisory Committee on Immunization Practices [2006]). UK data are available in the Department of Health ‘The Green Book’ available on the internet (Plotkin and Orenstein 2004; Department of Health Green Book).

Although there is a theoretical risk of live vaccine being present in breastmilk, vaccination with common vaccines is not contra-indicated for women who are breastfeeding when there is significant risk of exposure to disease. There is no evidence of risk from vaccinating women who are breastfeeding, with inactivated viral or bacterial vaccines or toxoids (BNF).

               Measles, mumps and rubella     

Rubella vaccine virus can appear in breastmilk and result in infections in some infants (Buimovici-Klein et al. 1977). There is no evidence of mumps and measles vaccine viruses being found in breastmilk. Some breastfed infants acquire passive immunity to rubella after maternal vaccination, as do infants of mothers with natural rubella immunity. However, neither group of infants has a decreased response to rubella vaccine administered directly (Krogh et al. 1989). The CDC (Kroger et al. 2006) state that vaccines given to a nursing mother do not affect the safety of breastfeeding for mothers or infants and that breastfeeding is not a contra-indication to MMR vaccine. Breastfed infants should be vaccinated according to the routine recommended schedules (Plotkin and Orenstein, 2004; Department of Health Green Book).

Compatible with use during breastfeeding.

Diptheria, tetanus and pertussis             

One study of previously vaccinated infants found that at 21 to 40 months of age breastfed infants had higher immunoglobulin G (IgG) levels against diphtheria, higher secretory IgA levels in saliva against diphtheria and tetanus and higher fecal IgM against tetanus than formula-fed infants (Hahn-Zoric et al. 1990).

Pisicane et al. (2010) found that breastfed infants were also less likely to have fever after immunisation than their non-breastfed counterparts. Lopez-Alarcon et al. (2002) found they were also less likely to experience loss of appetite and reduced energy intake after routine childhood immunisation than those who are not breastfed. Although baseline calorie intakes were higher in the formula-fed infants mean intakes fell by 12% in the post-immunisation period.

There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Kroger 2006; Plotkin and Orenstein 2004; Department of Health Green Book).

Compatible with use during breastfeeding.

               Meningococcal vaccination         

Immunisation of pregnant or lactating women with meningococcal vaccine increased the specific secretory IgA content of milk ( Shahid et al. 2002). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated virus or bacterial vaccines or toxoids (Granoff et al. 2004, Department of Health Green Book).

Compatible with use during breastfeeding.

Typhoid vaccination        ☺

Recommended as compatible with breastfeeding by the CDC and the American Academy of Pediatrics (AAP). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Kroger 2006; Plotkin and Orenstein 2004; Department of Health Green Book).

Compatible with use during breastfeeding.

Influenza vaccination    

Use of live, attenuated or inactivated vaccine is recommended as compatible with breastfeeding by the CDC and the AAP. There is no evidence of risk from vaccinating pregnant women, or those who are feeding, with inactivated viral or bacterial vaccines or toxoids (Plotkin and Orenstein 2004). Where possible, pregnant women should receive a thiomersal-free influenza vaccine (Department of Health Green Book ).

Compatible with use during breastfeeding.

BCG vaccination             

BCG vaccination against tuberculosis is recommended as compatible with breastfeeding by CDC and the AAP (Kroger 2006). Although no harmful effects on the foetus have been observed from BCG during pregnancy, it is wise to avoid vaccination, particularly in the first trimester, and wherever possible to delay until after delivery. Breastfeeding is not a contraindication to BCG (Plotkin and Orenstein 2004; Department of Health Green Book).

Compatible with use during breastfeeding.

Pneumococcal vaccines

Some evidence of decreased pneumococcal disease has been found among breastfed infants of vaccinated mothers (Lehmann et al. 2003). Pneumococcal-containing vaccines may be given to pregnant women when the need for protection is required without delay. There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Kroger 2006; Plotkin and Orenstein 2004; Department of Health Green Book).

Compatible with use during breastfeeding.

Varicella vaccine            

Recommended as compatible with breastfeeding by the CDC and the AAP (Kroger 2006). Women who are pregnant should not receive varicella vaccine and pregnancy should be avoided for 3 months following the last dose. Studies have shown that the vaccine virus is not transferred to the infant through breastmilk (Bohlke et al. 2003) and therefore breastfeeding women can be vaccinated if indicated (Plotkin and Orenstein 2004; Department of Health Green Book ).

Compatible with use during breastfeeding.

Yellow fever vaccine     

Until 2009 no adverse effects to yellow fever vaccine had been reported in infants exposed via breastfeeding. In 2009, the first case of meningoencephalitis caused by the yellow fever vaccine virus transmitted via breastmilk was confirmed.

Traiber et al. reported on a 38-day-old infant who was exclusively breastfed by a mother who had received yellow fever vaccination, the baby was discharged when convulsions resolved.

Kuhn et al. reported a case study of a previously healthy 5-week-old baby admitted to hospital with a 2-day history of fever and irritability, he subsequently fitted in the emergency department. When the baby was 10 days of age his mother was given travel vaccinations including yellow fever for a holiday to Venezuela. Hospital tests showed symptoms consistent with encephalitis. His symptoms resolved following a 21-day course of aciclovir.

The CDC (Kroger 2006) recommend against vaccinating nursing mothers with yellow fever vaccine before the baby is 6 months of age. However, if travel by the nursing mother to a high-risk yellow fever endemic area cannot be avoided or postponed, the mother may be vaccinated. Exposure to yellow fever vaccine via breastmilk would not increase the risk to an infant who receives the vaccination after the age of 6 months (Plotkin and Orenstein 2004, Department of Health Green Book ).

Compatible with use during breastfeeding. Avoid in first 6 months unless essential.

Hepatitis B vaccine        

Recommended as compatible with breastfeeding by the CDC and the AAP (Kroger 2006). Breastfed infants of hepatitis B surface antigen positive mothers have a different response in the development of Ig subtypes after vaccination with hepatitis B vaccine than do formula-fed infants. However, breastfeeding does not interfere with the infant’s antibody response to hepatitis B vaccine (Azarri et al. 1990; Wang et al. 2003). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Plotkin and Orenstein 2004; Department of Health Green Book ).

Compatible with use during breastfeeding.

Recommended as compatible with breastfeeding by the CDC and the AAP (Kroger 2006). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Plotkin and Orenstein 2004; Department of Health Green Book )

Cholera vaccine

Use of oral cholera vaccine to the mother decreased the risk of cholera in their breastfed infants by 47% in one study (Clemens et al. 1990). The authors hypothesised that vaccination of the mothers reduced their transmission of cholera to their infants. There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Kroger 2006; Plotkin and Orenstein 2004; Department of Health Green Book ).

Compatible with use during breastfeeding.

Polio vaccine    

Two types of poliomyelitis vaccine are available: inactivated poliomyelitis vaccine (for injection in combination with diphtheria vaccine) and live (oral) poliomyelitis vaccine.

Administration of oral poliovirus vaccine to nursing infants is less effective if it is given the neonatal period, due to maternal antibodies in colostrum and breastmilk (WHO 1995; Zaman et al. 1991). However, breastfeeding does not interfere with the infant’s response to oral polio vaccine, when given at the normal scheduled times (Kim-Farley et al. 1982; John et al. 1976). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids according to the CDC and the AAP (Kroger et al. 2006) and the Department of Health Green Book (Plotkin and Orenstein 2004; Department of Health Green Book  )

Compatible with use during breastfeeding.

Japanese encephalitis vaccine  

Recommended as compatible with breastfeeding by the CDC and the AAP (Kroger 2006) and the Department of Health Green Book (2013). There is no evidence of risk from vaccinating pregnant women or those who are breastfeeding with inactivated viral or bacterial vaccines or toxoids (Plotkin and Orenstein 2004).

Compatible with use during breastfeeding.
