Anyone who has had anaphylaxis or any other severe allergic reaction after a vaccine should
not be vaccinated again until the cause of the reaction has been determined. Anaphylaxis is a
severe allergic reaction in which the person goes into shock and has difficulty breathing. It
usually occurs within minutes of exposure to the source of the allergy.
Anyone with a serious disorder of the immune system should not receive live virus vaccines
such as oral polio, measles, mumps and rubella vaccines. This includes persons with severe
congenital immune deficiency disorders, persons receiving chemotherapy for cancer,
persons who have had a bone marrow or other organ transplant, and persons receiving high
doses of steroids. |
