Flu shot

Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Inactivated strains of type A and B Influenza virus vaccines.

Both inactivated (flu shot) or live-attenuated (nasal spray) vaccines are compatible with breastfeeding. (Canadá 2023, AAP 2022, CDC 2021, Red Book 2021-24 p.455, CAV-AEP 2019, Lawrence 2016 p402,​​​​​ Briggs 2015)

Vaccines are usually compatible with breastfeeding either if they are formed by live, attenuated, inactivated, death strains or microorganism toxoid. Except for rubella vaccine, they are not excreted into breast milk and do not cause harm to the infant. Yellow fever vaccine has a higher risk for harm effect on infants younger than 6 months old. 

Breastfeeding may enhance antibody response to vaccines and cause fewer side effects as fever or anorexia.

Early postpartum period is appropriate to get mothers vaccinated against measles, rubella and mumps in case they were not immunized.

Breastfeeding mothers should be protected by providing recommended vaccination for adults.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
