GENEVA/LONDON (Reuters) – Trials of Ebola vaccines could begin in West Africa in December, a month earlier than expected, and hundreds of thousands of doses should be available for use by the middle of next year, the World Health Organization said on Friday.
Vaccines are being developed and made ready in record time by drugmakers working with regulators, the U.N. health agency said, but questions remain about their safety and efficacy which can only be settled by full clinical trials.
GENEVA/LONDON (Reuters) – The World Health Organization (WHO) set out plans on Friday for speeding up development and deployment of experimental Ebola vaccines, saying hundreds of thousands of doses should be ready for use in West Africa by the middle of 2015.
The Geneva-based United Nations health agency confirmed that two leading vaccine candidates are in human clinical trials, and said another five experimental vaccines were also being developed and would begin clinical trials next year.
GENEVA/LONDON (Reuters) – The World Health Organization (WHO) said on Thursday it was “reasonably confident” that the Ebola virus plaguing three West African countries had not spread into neighboring states.
Asked whether countries such as Guinea Bissau and Ivory Coast might have cases of the disease crossing their borders without knowing about or reporting them, WHO assistant director general Keiji Fukuda said he considered that unlikely.
LONDON (Reuters) – As researchers from Africa to China to America race to develop vaccines and treatments to fight Ebola, health experts are grappling with the economics of a disease that until this year had been off the drug industry’s radar.
Whether or not effective drugs come in time to turn around the world’s worst epidemic of the virus ravaging three West African countries, the world will want stockpiles to protect against inevitable future outbreaks, experts say.
LONDON (Reuters) – Multi drug-resistant tuberculosis remains at crisis levels, with about 480,000 new cases this year, and various forms of the lung disease killed about 1.5 million people in 2013, the World Health Organization (WHO) said on Wednesday.
In recent years, the emergence of multi drug-resistant TB — a manmade problem caused by regular TB patients being given the wrong medicines, the wrong doses, or failing to complete their treatment — has posed an increasing global health threat.
LONDON (Reuters) – Three Ebola-infected travelers a month would be expected to get on international flights from the West African countries suffering epidemics of the deadly virus if there were no effective exit screening, scientists said on Tuesday.
The three countries, Guinea, Liberia and Sierra Leone, do all check departing air passengers for fever, although the test cannot spot sufferers in the period before they show symptoms, which can be up to 21 days.
LONDON, Oct 21 (Reuters) – A Bulgarian man who was paralysed
from the chest down in a knife attack can now walk with the aid
of a frame after receiving pioneering transplant treatment using
cells from his nose.
The technique, described as a breakthrough by a study in the
journal Cell Transplantation, involved transplanting what are
known as olfactory ensheathing cells into the patient’s spinal
cord and constructing a “nerve bridge” between two stumps of the
damaged spinal column.
LONDON (Reuters) – Scientists studying fossils have discovered that the intimate act of sexual intercourse used by humans was pioneered by ancient armored fishes, called placoderms, about 385 million years ago in Scotland.
In an important discovery in the evolutionary history of sexual reproduction, the scientists found that male fossils of the Microbrachius dicki, which belong to a placoderm group, developed bony L-shaped genital limbs called claspers to transfer sperm to females.
LONDON (Reuters) – Exercising three times a week reduces the odds of developing depression by around 16 percent, scientists said on Wednesday — and for every extra weekly activity session, the risk drops further.
In a study conducted as part of a public health research consortium, the UK-based scientists said the relationship they found between depression and exercise points to ways to simultaneously improve both mental and physical health.
GENEVA/LONDON (Reuters) – The Ebola epidemic is still spreading in Guinea, Sierra Leone and Liberia and the number of cases in West Africa will exceed 9,000 this week, the World Health Organization (WHO) said on Tuesday.
The death toll so far in the outbreak, first reported in Guinea in March, has reached 4,447 from a total of 8,914 cases, WHO Assistant Director General Bruce Aylward said.
