“Many Ebola vaccine candidates had been developed in the decade prior to 2014,[101] but as of November 2014, none had been approved for use in humans in the United States.[102][103][104] In December 2016, Ebola was found to be 70–100% prevented by rVSV-ZEBOV vaccine, making it the first proven vaccine against the disease.[105][106][7] More than 100,000 people have been vaccinated against Ebola as of 2019.[107]”
