Correct answer: B — Offer catch-up vaccination according to the UKHSA schedule

Missed routine vaccines should be caught up according to the UKHSA schedule rather than restarting completed courses. Live vaccines are not avoided in a healthy child because of age alone. Antibiotics do not improve vaccine safety or effectiveness. The pearl is that catch-up immunisation uses age, prior doses and spacing rather than a simple restart rule.
