Ring vaccination: The vaccination of all susceptible individuals in a prescribed area around an outbreak of an infectious disease.
Depending on how easily the disease spreads, contacts who could have been infected might include family, neighbours, and friends. If there is a tight geographic community boundary, it may be preferable to vaccinate the entire community in which the illness has appeared, rather than explicitly tracing contacts.Many vaccines take several weeks to induce immunity, and thus do not provide immediate protection.When responding to a possible outbreak, health officials should consider which is best, ring vaccination or In 2018, health authorities used a ring vaccination strategy to try to suppress the With no vaccine to protect against COVID-19 yet, a large number of people would need to catch the virus, get sick, and recover before we can have herd immunity.

During 2014–2015, trials of candidate vaccines for Ebola virus disease (EVD) were fast tracked in response to the unprecedented EVD epidemic in West Africa ().In March 2015, a phase 3 ring vaccination trial of a recombinant vesicular stomatitis virus–Zaire Ebola virus vaccine began in Guinea ().Interim trial results suggested that the vaccine could have a high level of efficacy in humans (). Objectives & Goals/Procedures: Learning Objectives: Being able to understand the principles of Herd Immunity and Ring Vaccination and the impact of the vaccines in our country and the world on public health over the past century. It states that the more people are immune to an infectious agent, the less likely an immune-compromised individual is to come in contact with it. Will you be able to eradicate the virus with these vaccines? Ring vaccination controls an outbreak by vaccinating and monitoring a ring of people around each infected individual.
