Which statement is NOT a contraindication to routine vaccination?

• A. Immunocompromised patient
• B. Recent antimicrobial therapy
• C. History of nonspecific allergies
• D. Mild acute illness

Answer: (D)

Not a contraindication is mild acute illness. A child with a mild fever, runny nose, or other mild, self-limited illness can still safely receive routine vaccines. Delaying vaccination for every minor illness would leave children unprotected longer and can lead to under-immunization. The immune system is capable of mounting a response to the vaccine even during a mild concurrent illness, and most guidelines explicitly allow vaccination in the setting of mild, non-severe acute illness. In contrast, certain situations require caution or withholding specific vaccines. Immunocompromised status is important because live vaccines can pose a risk in those with significantly reduced immune function, so eligibility for those vaccines is assessed carefully. Recent antimicrobial therapy alone does not generally preclude vaccination—the antibiotics do not interfere with a vaccine’s safety or effectiveness, provided the child is otherwise well. A history of nonspecific allergies is not itself a contraindication; only a true allergic reaction to a previous vaccine dose or to a vaccine component would raise concerns about giving that vaccine.
