What are the contraindications of the IPV vaccine?

• A. Allergy to neomycin, streptomycin, and polymyxin B
• B. Allergy to penicillin
• C. Pregnancy
• D. Cancer

Answer: (A)

IPV is an inactivated vaccine, so true contraindications are about allergic reactions to its components. A severe allergy to the antibiotics used in its manufacture—neomycin, streptomycin, or polymyxin B—means IPV should not be given, because even tiny amounts can trigger a reaction. Allergies to penicillin aren’t relevant here since penicillin isn’t a component of IPV. Pregnancy and cancer are not absolute contraindications for IPV; the vaccine can be given when indicated, though clinical judgment about immune status and timing may apply in special cases.
