WHO to use Ebola vaccine to stem outbreak in remote area of Congo

The WHO said on Friday that it believes to deploy an experimental Ebola vaccine to tackle an outbreak in a local area of Congo to prevent it spreading, particularly to the provincial capital of a million people.

Congo reported the outbreak on Tuesday, with 32 victims, probable or confirmed cases of the disease on 4th of April, including 18 deaths.

A new suspected case was reported on Friday. The WHO is moving swuftly, having been criticised for bungling its action to a 2014-2016 outbreak that killed more than 11,300 people in Guinea, Sierra Leone and Liberia.

“We are very concerned and planning for all scenarios, including the worst one,” Peter Salama, WHO’s Deputy Director-General of Emergency Preparedness and Response, tall to a regular U.N. briefing in Geneva.

The outbreak area is 15 hours by motorbike from the closest town and has “absolutely dire” infrastructure, Salama said, so the WHO wants to send in 20 to 40 professional by helicopter this weekend and then clear an airstrip for enough supplies.

“This is going to be tough and it’s going to be costly to stamp out this outbreak,” he said. The immediate danger was to the provincial capital Mbandaka, with about one million inhabitants, but Congo’s nine neighbours have also been put on quick alert in case the disease crossed a border, especially by river to the Republic of Congo or Central African Republic.

Normally a remote setting would reduce the chance of the disease spreading. But already there are 3 different locations covering 60 km or more, and some of the victims were health workers, potentially “an amplification factor” for outbreaks, Salama said.

The local culture, with traditional healers and communal burials where there was close contact with the deceased, could cause “super-spreading” of Ebola, which kills up to 90 per cent of sufferers, he said.

Salama said he spoke to Congo’s Health Minister Oly Ilunga on Thursday and hoped to get approval within days to utilise a vaccine developed by Merck in 2016.

Although highly effective, it is still experimental, has not been licensed, and must be kept at -60 to -80 degrees Celsius (-76°F to -112°F).

“This is a highly complicated, sophisticated operation in one of the most difficult terrains on earth,” Salama said.

It can be used to protect people who have had contact with Ebola victims, stopping the spread of disease, but that requires intensive contact tracing, which Salama said could take a week or two just for the cases already documented.

Ilunga said on Thursday that the risk to urban areas and cases among healthcare workers made the outbreak worrisome, and that health workers might be the priority for vaccination.

Salama said that WHO was preparing for the green light and hoped to have a mobile laboratory operational over the weekend, and that both WHO and the medical charity Medecins Sans Frontieres already had a team on the ground.

“The cold chain is on standby, the stockpile is on standby, the teams have been put on standby including up to 40 people that conducted the initial ring vaccination trial in Guinea.”

Salama also said there was no evidence of a link between the outbreak and eight deaths that occurred in January and February in the same area, which had not been confirmed as Ebola.
