Objective: To clarify whether a lactating mother can give breast milk after vaccination for the mumps virus.
Material and Methods: A mother with a negative antibody titer for mumps virus had breastfed since before receiving a mumps viral vaccination and continued maternal feeding after inoculation. RT-LAMP and nested RT-PCR were used to examine breast milk samples 15, 22, 29, 42, and 49 days after the vaccination.
Results: RT-LAMP was only positive for mumps virus in the breast milk 29 days after vaccination. Samples measured using nested RT-PCR were positive 29 and 42 days after the vaccination.
Conclusions: The baby did not develop mumps, despite being fed with breast milk including the mumps viral vaccine strain. It will be necessary to determine whether babies can acquire immunity through exposure to a viral vaccine strain via breast milk.
