Immunizations given to the mother do not require her to stop breastfeeding. On the contrary, the immunization will help the baby develop immunity to that immunization, if anything gets into the milk. In fact, most of the time nothing does get into the milk, except, possibly some of the live virus immunizations, such as German Measles. And that’s good, not bad.
X-rays and scans. Ordinary X-rays do not require a mother to interrupt breastfeeding even when used with contrast material (example, intravenous pyelogram). The reason is that the material does not get into the milk, and even if it did it would not be absorbed by the baby. The same is true for CT scans and MRI scans.
