Sample item

Which approach protects young infants against severe RSV bronchiolitis in the first months of life?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Nirsevimab monoclonal antibody to the infant, or maternal RSV vaccine in late pregnancy

Nirsevimab is a long-acting monoclonal antibody given to infants, and maternal RSV prefusion F vaccine during pregnancy gives passive antibody protection. Both reduce RSV hospitalisation in young infants.

Option by option

  • A. BCG vaccine

    BCG does not protect against RSV.

  • B. Antibiotic prophylaxis

    Antibiotics do not prevent viral infection.

  • C. Oral zinc

    Zinc has no role in RSV prevention.

  • D. Nirsevimab monoclonal antibody to the infant, or maternal RSV vaccine in late pregnancy (correct)

    Correct. These are the two approved strategies.
