The next steps in testing Ebola vaccines as well as a picture of how they might be used in West Africa's outbreak region became clearer today as officials from the World Health Organization (WHO) shared the outcome of yesterday's (Thursday's) high-level meeting in Geneva.
Large phase 3 trials in West Africa's outbreak setting will be next up to see if the vaccines work, with the studies designed to collect more safety data, a task usually covered in phase 2 trials, experts involved in the meeting said today at a WHO media telebriefing. However, as Ebola infections drop off in the outbreak region, scientists face a closing window of opportunity to see how the vaccines perform in a real-life setting.
Experts also signaled a possible role for two Ebola vaccine formulations: a single-dose vaccine providing shorter-term immunity that could be used to tamp down Ebola flare-ups and a prime-boost vaccine that may provide more durable immunity and could be used for other immunization strategies.
Latest surveys point to declines in employment, food insecurity, and long-term welfare concerns

WASHINGTON-- The socio-economic impacts of Ebola in Liberia and Sierra Leone are far-reaching and persistent, according to two new World Bank Group reports. Both countries continue to experience job losses, despite their differing health outlooks. These impacts have not been limited to the areas where infections have been the highest, which points to economy-wide slowdowns. As a result, many households have been forced to take short-term actions to cope, which can have substantial long-term effects on welfare.
“The Ebola virus itself must be eradicated- this is the number one priority,” said Ana Revenga, Senior Director for Poverty at the World Bank Group. “But its socio-economic side effects put the current and future prosperity of households in Liberia and Sierra Leone at high risk. We must pay careful attention to those who are most vulnerable to both health and economic shocks, and ensure that they are supported throughout and after the crisis.”
Ebola is causing mental health problems in Sierra Leone, with the country’s overstretched health system unable to deal with the psychosocial legacy of the outbreak, according to a report by the International Medical Corps (pdf).

LONDON- A British nurse diagnosed with Ebola last month is recovering and is no longer in a critical condition, the London hospital treating her said in a statement on Monday.
Pauline Cafferkey, a 39-year-old nurse who normally works at a Scottish health center, became the first person to be diagnosed with the disease in Britain after contracting it in Sierra Leone where she was volunteering at an Ebola clinic.
"Pauline Cafferkey is showing signs of improvement and is no longer critically ill," the statement from the Royal Free Hospital said. "She remains in isolation as she receives specialist care for the Ebola virus."
Cafferkey is being treated with blood plasma from an Ebola survivor and an unnamed experimental anti-viral drug, the hospital has said.
As authorities and drug companies hurriedly prepare to begin testing Ebola vaccines in West Africa, they are starting to contemplate a new challenge: whether an ebbing of the outbreak could make it more difficult to determine if the experimental vaccines are effective.
A district in Sierra Leone has been declared Ebola-free, the first to be given the all-clear after 42 days with zero recorded cases of the virus.

Pujehun, in the south-east of the country, was hit by Ebola in August and suffered 24 deaths from 31 cases – but it has not had a recorded case since 26 November. This means it has achieved the World Health Organisation’s benchmark for Ebola-free status.

Kailahun district in eastern Sierra Leone was one of the country’s first hotspots in the Ebola outbreak, at its peak reporting more than 80 new cases per week in late June 2014. With the assistance of WHO and partners, combined with the close involvement of community leaders, the district has managed to beat the disease and has reported no new cases for several weeks. There is no room for complacency however. Community teams and health workers are on high alert and are ready to react quickly to any possible new infection.

Making the decision to volunteer in an Ebola Treatment Unit (ETU) in West Africa shows a lot of courage and takes support from friends, loved ones, and other healthcare workers. It also requires the knowledge and skills to safely treat very sick patients in a challenging environment. CDC understands that healthcare workers preparing to deploy to West Africa need to know the infection prevention and control principles necessary for working in an ETU. To help meet this need, CDC offers an introductory training course at the Federal Emergency Management Agency’s (FEMA) Center for Domestic Preparedness in Anniston, Alabama.

There is currently one patient in the clinic, which is perched on a hill in the compound of a disused Methodist boys high school in the Sierra Leone capital.
Women are particularly vulnerable to a disease spread through direct contact with infected people and with the corpses of victims, because women often care for sick family members, said MSF Field Coordinator, Esperanza Santos.

FREETOWN, Sierra Leone --
...Whether the world's worst-ever Ebola outbreak can be wiped out in West Africa in 2015 is uncertain. To a large extent, it depends as much on locals changing their practices and beliefs as it does on continued international assistance.
One of the biggest problems is finding all contacts of confirmed cases. Teams are in place in Guinea, Liberia and Sierra Leone, the three worst-hit countries, to monitor suspect cases, but too little is known about where the virus is spreading. Typically, every confirmed Ebola case has about 12 to 20 possible contacts who must be monitored. In Sierra Leone, the epicenter of the current crisis, officials are reporting just eight, leading to suspicions that contact tracing is inadequate....
Among concrete progress since the crisis gained international attention last summer, a major initiative led by the U.N. has been put into place, including:
Australian researchers reported on an automated text-message system used for actively monitoring people potentially exposed to Ebola. The system prompts contacts to submit information on symptoms and temperature twice a day. The Department of Health in Western Australia uses the system, called "EbolaTracks," to track travelers returning from West Africa and (potentially) contacts of any local cases.
Twenty-two people were enrolled in the program as of Jan 5, and 14 have completed active monitoring. The system sent 1,108 text messages and got a 91% response rate. Health officials followed up by phone when they didn't get a reply. Such systems could be valuable tools for larger-scale contact monitoring for Ebola or other infectious diseases, they concluded.

ASSOCIATED PRESS by Maria Cheng Jan. 9, 2015 LONDON --The World Health Organizationsays the two leading Ebola vaccines appear safe and will soon be tested in healthy volunteers in West Africa.
After an expert meeting this week, WHO said there is now enough information to conclude that the two most advanced Ebola vaccines ? one made by GlaxoSmithKline and the other licensed by Merck and NewLink ? have "an acceptable safety profile."
In a press briefing on Friday, Dr. Marie-Paule Kieny, who heads WHO's Ebola vaccine efforts, said "the cupboard (for Ebola vaccines) is filling up rapidly."
She said further trials in healthy people in West Africa, including health workers, are scheduled to start soon. Kieny added several other vaccines were being developed in the U.S., Russia and elsewhere.
GENEVA--The United Nations World Health Organization (WHO) today convened in Geneva its second ever high-level meeting on Ebola vaccines access and financing, to review the current status of clinical trials and plans for Phase II and Phase III efficacy trials.

“We are here to take stock, plan the next steps, and make sure that all partners are working in tandem. We all want the momentum and sense of urgency to continue,” Dr. Margaret Chan, Director-General of WHO said as she kicked off the meeting.
The most advanced candidate Ebola vaccine is scheduled to enter Phase III efficacy clinical trials in West Africa in January/February 2015, and if shown effective – will be available for deployment a few months later.
