ring vaccination
Outbreak perimeter immunization
Ring vaccination is a containment strategy where vaccines are administered to everyone in contact with an infected person, and then to contacts of those contacts, forming protective "rings" around confirmed cases.
The approach aims to halt disease spread without vaccinating entire populations: Ring vaccination helped eradicate smallpox.
It works best when vaccines provide rapid immunity and cases can be quickly identified and traced.
