Prompt
Parent of a 14-month-old in temporary housing; incomplete immunisations; parent read that an unvaccinated child is 'many times more likely' to catch measles and also says 'herd immunity will cover us'; asks for a commercial multi-disease blood panel 'for peace of mind' instead of vaccines.
Station tasks
Build rapport and explore housing and access barriers without blame. Explain absolute versus relative risk in plain language. Correct the herd-immunity misconception without shaming. Offer a concrete catch-up immunisation plan with a named follow-up owner. Decline the commercial multi-disease panel as a substitute for vaccination, explaining pathway and net-benefit reasons. Safety-net for fever after vaccines and for access problems. [1] [2] [3] [4] [5] [7]
