CDC announces study results for ring vaccination efficacy against Ebola

CDC announces study results for ring vaccination efficacy against Ebola.

The U.S. Centers for Disease Control and Prevention (CDC) recently released a study from the London School of Hygiene and Tropical Medicine, indicating the efficacy of ring vaccination for the Ebola virus.

This study will be released in the Jan. 2016 volume of the CDC’s Emerging Infectious Diseases journal. According to researchers, the ring vaccination method of treatment has potential to end the outbreak because of more effective control methods and fewer cases than at the peak of the outbreak.

Ring vaccination refers to the practice of vaccinating all individuals that have come into contact with a pathogen and later vaccinating those who might have come into contact with the first group.

The study utilized transmission models based off case data from Guinea; in several scenarios, they found that missed cases would cause large outbreaks past the point of vaccination efforts, and as a result they would not be contained.

This method was found by researcher to be ineffective at the peak of the outbreak due to the high number of cases, many of which are unidentified. Should a vaccine for the Ebola virus complete the development cycle, they suggest that hybrid strategies involving mass vaccinations and ring vaccination programs would be necessary to combat future outbreaks.
