Thorning to visit Ebola workers in Sierra Leone

Danish PM's trip to "show support and solidarity" will mark the first time a Western leader has travelled to Sierra Leone since the outbreak of Ebola.

Denmark's Prime Minister Helle Thorning-Schmidt begins a visit to Sierra Leone on Monday, making her the first Western leader to travel to the African nation since it was hit by a deadly Ebola outbreak.
 
The epidemic "can only come under control if we help each other. It is a long and persistent struggle that we cannot forget in our part of the world," she told Berlingske.
 
"It is important that countries like Denmark show support and solidarity with Sierra Leone and other west African countries affected by Ebola," she said.
 
Thorning-Schmidt will visit a group of 19 Danish healthcare workers who were sent to the northeastern town of Port Loko in December to work at an Ebola treatment centre.
 
She will also visit a Danish transport ship used to bring UN vehicles into Sierra Leone, Liberia and Guinea.
 
 
The three countries account for 99 percent of the estimated 8,500 Ebola deaths out of more than 21,000 cases reported since December 2013, according to the latest World Health Organization report.
 
The UN's Ebola coordinator David Nabarro said Thursday the crisis has "passed the tipping point" and there is now a reasonable chance the deadly outbreak could end quickly.
 
Liberia reported its lowest weekly number of new cases since early June, while Guinea and Sierra Leone both saw the fewest new cases since August, Nabarro said in his most recent update.

Spanish researchers develop five-strain vaccine against lethal Ebola virus

Spanish researchers are working on a vaccine against all five strains of the killer Ebola virus in what would be a world first, Madrid's October 12 Hospital said Wednesday (July 11).

A prototype vaccine developed by pharmaceutical group Merck is already in use, but acts only against the most virulent, “Zaire” strain.

Despite not having market approval, Merck's rVSV-ZEBOV was administered to people in the Democratic Republic of Congo in May, with UN approval, in a bid to contain an outbreak of the same virus that killed more than 11,300 in three West African countries from 2013 to 2015, sparking international panic.

For several months, a team from the October 12 Hospital has been working with researchers at two other hospitals in the capital to examine and learn from blood samples taken from three people cured of Ebola in Spain.

Lead researcher Rafael Delgado told reporters the difficulty lay in the fact that the virus protects itself with proteins that act as a shield, and only exposes its vulnerable zones for short periods of time.

That makes it tough for the body's immune system to fight the virus.

The three Spanish patients had produced “very effective” viral antibodies, though in a “small quantity” and only against the Zaire strain they were contaminated with.

Delgado, head of microbiology at the hospital, said researchers are aiming to reproduce these antibodies on a larger scale, and in a way that would make them efficient against all five virus strains.

US medical giant Johnson & Johnson is separately developing an experimental vaccine against two Ebola strains.

Delgado said researchers hope to get results from mouse experiments within a year.

The Ebola epidemic caused alarm in Spain in 2014 when a nursing assistant, Teresa Romero, became the first person infected outside Africa.

She caught the disease while tending to a Spanish missionary repatriated from Sierra Leone, who died in Spain in September that year.
