A mother asks whether an antibiotic can replace vaccination against polio for her healthy infant. Which teaching point is correct?

Correct answer: B. Vaccination helps prevent infection by stimulating immunity

  • A. Antibiotics create immune memory against polio
  • B. Vaccination helps prevent infection by stimulating immunity
  • C. Antibiotics permanently neutralise polio vaccine reactions
  • D. Vaccination treats paralysis after polio infection develops

Explanation

Vaccination stimulates the infant’s immune system to develop protection before exposure to poliovirus. Antibiotics do not create antiviral immune memory, and a vaccine is preventive rather than a treatment for established paralytic polio.
