Where can I find information about the special vaccine needs of patients with immunodeficiencies caused by a by a medical condition or treatment, including stem cell transplants?

Due to the variety of causes and consequences of altered immunocompetence, and limited studies of vaccination with these conditions, vaccination recommendations for primary and secondary immunodeficiencies are generally based upon expert opinion.

CDC’s “General Best Practices for Immunization” includes a subsection for vaccine recommendations for people with altered immunocompetence here: www.cdc.gov/vaccines/hcp/imz-best-practices/altered-immunocompetence.html. For a summary of specific vaccine recommendations for people with different types of primary and secondary immunodeficiencies, refer to Table 8-1 at that site.
