💉 Ebola spread is slowing and vaccines are on the way

• The spread of Ebola is declining in most of the affected provinces in Congo, according to the WHO.
• A large Phase 3 trial of Ebola vaccines is expected to start within the next few weeks.
• Frontline workers will be offered a vaccine in a separate study that starts within days.

Transmission is falling in several provinces

The World Health Organization (WHO) sees reason for cautious optimism about the Ebola outbreak in the Democratic Republic of the Congo (which is not a democracy). That was the message from WHO Director-General Tedros Adhanom Ghebreyesus at a news conference.

According to Tedros, transmission rates are declining in most of the affected provinces. The number of cases has also fallen in Ituri province, the epicenter of the outbreak.

The outbreak is caused by the Bundibugyo species of Ebola. As of September 13, there had been 7,258 confirmed cases and 3,510 deaths. The cases are spread across seven provinces in northeastern Congo. It is the second-largest Ebola outbreak on record.

Better cooperation with residents

Tedros visited the area early in the outbreak. At the time, he met many residents who saw Ebola as a lesser problem than malaria, hunger and political violence. The region has been wracked by armed conflict for decades, and many people have been forced to flee their homes.

That view has now changed. According to Tedros, cooperation has improved. Residents have begun to realize that the disease is serious.

Large vaccine trial on the way

The WHO expects a randomized Phase 3 trial of Ebola vaccines to begin within the next few weeks. The first vaccine to be used is Ervebo from the drugmaker Merck. It was developed to target the Zaire Ebola virus. There is some evidence that it may also protect against the Bundibugyo species.

Vaccines designed specifically to target Bundibugyo will also be added to the trial. This will happen once they have completed early safety and dosing studies. That was according to Meg Doherty, director of the WHO's department of science for health.

The drugmaker Moderna has also launched an early trial of an mRNA vaccine against Ebola.

Vaccines for frontline workers

In parallel, frontline workers in the areas where the virus is spreading most will be offered a vaccine. This will take place in an observational study expected to start later this week or early next week. The study is being conducted by Congolese authorities and Doctors Without Borders.

Participants first receive a dose of Ervebo. A month later, they receive a dose of an experimental vaccine designed to protect against the Sudan version of the Ebola virus. Researchers will then compare the number of cases among people who were vaccinated with the number among those who were not.
