I'm exclusively breastfeeding. Does breast milk affect how much protection my baby gets from vaccines?

Don't worry — breast milk doesn't reduce vaccine protection; in fact, it supports your baby's immune system. Breast milk antibodies (especially IgA) protect against infections while vaccines build your baby's own immune memory. They work together, not against each other. AAP (American Academy of Pediatrics) and WHO recommend fully vaccinating breastfed babies on the same schedule. Only in rare cases of very premature or immunocompromised babies does a doctor need to evaluate differently — your situation doesn't require concern. Keep breastfeeding, stay on the vaccine schedule.
