Ebola Vaccines[edit | edit source]

Microscopic view of the Ebola virus

Introduction[edit | edit source]

Ebola vaccines are medical vaccines developed to prevent the spread of Ebola, a deadly virus that causes severe viral hemorrhagic fever in humans. The development of these vaccines has been a critical part of the global health response to Ebola outbreaks.

History and Development[edit | edit source]

The quest for an effective Ebola vaccine accelerated during the early 21st century. Several vaccine candidates were developed and tested for their efficacy, particularly in protecting nonhuman primates, like macaques, against lethal Ebola infection.

rVSV-ZEBOV: The First Approved Ebola Vaccine[edit | edit source]

In December 2019, rVSV-ZEBOV became the first Ebola vaccine approved in the United States. Key aspects of this vaccine include:

Extensive use in the Kivu Ebola epidemic under a compassionate use protocol
High efficacy rate in preventing Ebola virus disease

Other Vaccine Candidates[edit | edit source]

In addition to rVSV-ZEBOV, several other Ebola vaccine candidates have been under development and testing. These include:

Ad26.ZEBOV/MVA-BN-Filo vaccine regimen
cAd3-EBO Z
Ebola Sudan vaccine candidates

Clinical Trials and Usage[edit | edit source]

Ebola vaccines have undergone rigorous clinical trials to ensure their safety and effectiveness. These vaccines have been used in various Ebola outbreak regions, significantly reducing the spread of the virus.
