Effectiveness of Ring Vaccination as Control Strategy for Ebola Virus Disease PDF Version [PDF – 463 KB – 4 pages]
A. J. Kucharski et al.
Abstract
Using an Ebola virus disease transmission model, we found that addition of ring vaccination at the outset of the West Africa epidemic might not have led to containment of this disease. However, in later stages of the epidemic or in outbreaks with less intense transmission or more effective control, this strategy could help eliminate the disease.
…Conclusions
Ring vaccination enhances standard public health measures of contact tracing, isolation, and community engagement (14) and could be effective when such measures are in place. However, if standard measures are not working because many cases are not in known transmission chains, as in West Africa in early 2014, ring vaccination might be insufficient to contain the outbreak. If an EVD vaccine is shown to be efficacious, our results suggest that mass vaccination, or hybrid strategies involving mass and ring vaccinations, might need to be considered alongside ring vaccination when planning for future outbreaks.
