WHO gets approval to use Ebola vaccine in DR Congo WHO has been given the go-ahead by officials in the DR Congo to import and use an experimental Ebola vaccine in the country. WHO Director-General Tedros Adhanom Ghebreyesus told the media that formalities have been agreed on and that the vaccine is ready to be used. Vaccinations could begin by next Monday. The vaccine, developed by Merck in 2016, has proven safe and effective in human trials, but it is still experimental as it does not yet have a licence. The shot, which was tested in Guinea in 2015 at the end of a vast Ebola outbreak in West Africa, is designed for use in a “ring vaccination” approach, requiring that persons who get in contact with an Ebola patient, are traced and vaccinated to try and prevent the spread of the disease SOURCE: africanews ---DECRYPTED---
