In general, it is safe for breastfeeding women to receive a vaccination should it be needed. If unsure, each mother should check with her health care provider for information about a particular vaccination.

It is well known that breastfed babies are less likely to get infections than formula-fed babies.
Breastfeeding and immunity
Breastfeeding and immunity | Australian Breastfeeding Association
Back to Children's health. During the last 3 months of pregnancy, antibodies from the mother are passed to her unborn baby through the placenta. This type of immunity is called passive immunity because the baby has been given antibodies rather than making them itself. Antibodies are special proteins the immune system produces to help protect the body against bacteria and viruses. For example, if the mother has had chickenpox , she'll have developed immunity against the condition and some of the chickenpox antibodies will be passed to the baby. Immunity in newborn babies is only temporary and starts to decrease after the first few weeks or months.

This protects babies from infections at a time when their own immune system is still immature.
