An excellent resource for vaccine contraindications and precautions is the CDC online resource, “General Best Practice Guidelines for Immunization”. A table in the Contraindications and Precautions chapter has a listing for all routine vaccines in the United States available at?www.cdc.gov/vaccines/hcp/imz-best-practices/contraindications-precautions.html. In addition, a table of contraindications and precautions is provided in the appendix of current CDC recommended adult and child/adolescent immunization schedules, available at www.cdc.gov/vaccines/hcp/imz-schedules.
