Ebola vaccines are vaccines either approved or in development to prevent Ebola. As of 2022, there are only vaccines against the Zaire ebolavirus. The first vaccine to be approved in the United States was rVSV-ZEBOV in December 2019.[9][10] It had been used extensively in the Kivu Ebola epidemic under a compassionate use protocol.[11] During the early 21st century, several vaccine candidates displayed efficacy to protect nonhuman primates (usually macaques) against lethal infection.[12][13][14]

Vaccines include replication-deficient adenovirus vectors, replication-competent vesicular stomatitis (VSV) and human parainfluenza (HPIV-3) vectors, and virus-like nanoparticle preparations. Conventional trials to study efficacy by exposure of humans to the pathogen after immunization are not ethical in this case. For such situations, the US Food and Drug Administration (FDA) has established the "animal efficacy rule" allowing licensure to be approved on the basis of animal model studies that replicate human disease, combined with evidence of safety and a potentially potent immune response (antibodies in the blood) from humans given the vaccine. Clinical trials involve the administration of the vaccine to healthy human subjects to evaluate the immune response, identify any side effects and determine the appropriate dosage.[15]
