Expert Q&A: Childhood Vaccine Safety

My child has a weakened immune system. Is it safe to vaccinate?

Again, it depends on the level of weakened immunity. If the child has leukemia or other types of cancer, or AIDS, they should not receive vaccines with live weakened or live attenuated vaccines.  Examples of these include measles, intranasal influenza. Obviously any decisions ... should be made on a case-by-case basis in consultation with the child's doctor.

We are talking about live vaccine. ... Most of the other vaccines are inactivated. Inactivated vaccines can be administered safely to persons with altered immunocompetence.
