Temporary precautions for vaccines include which condition?

• A. Moderate or severe illness
• B. Pregnancy
• C. Recent recipient of antibody-containing products
• D. Immunosuppression

Answer: (A)

Moderate or severe acute illness signals that the body is already fighting an infection, so delaying vaccination helps ensure the immune system can respond adequately to the vaccine once you’ve recovered. Postponing also avoids confusing any illness symptoms with vaccine side effects and reduces the chance of vaccine reactions being mistaken for the illness. Once the person has recovered, vaccination can proceed.

Mild illnesses without fever are generally not a reason to postpone. Other situations, like pregnancy, recent receipt of antibody-containing products, or significant immunosuppression, involve more specific vaccine decisions, but they are not the universal temporary precaution for all vaccines like a moderate to severe acute illness is.
