Uganda is starting a test of a vaccine to fight a dangerous kind of Ebola virus. This virus has already killed one person and made others sick. Health workers and people who were near the sick person will get the vaccine. The trial started quickly after the nurse's death in Uganda. Two more cases were found in the nurse's family. This is the sixth time Uganda has had this kind of Ebola outbreak, and there is no approved vaccine for it. There are different kinds of Ebola, but only one has a vaccine. The worst Ebola outbreak happened in West Africa from 2013 to 2016 and killed many people. The World Health Organization (WHO) is helping with the vaccine trial. They are giving the first shots to people who were close to the sick person and their family members. Ebola spreads through body fluids and causes symptoms like fever and bleeding. Uganda has had many outbreaks of this type of Ebola, as well as Sudan and the Democratic Republic of the Congo. In 2020, a deadly Ebola outbreak in Congo killed over 2,000 people. This vaccine trial is important to stop the spread of Ebola and keep people safe. Doctors and scientists are working quickly to help those who are sick and prevent more people from getting the virus.
