Universal Flu Vaccine Effective in Humans
For the first time, scientists have shown that a universal flu
vaccine is effective in humans.
Unlike current flu vaccines, the universal vaccine does not need
to be changed every year to match the latest flu strain, the team
at Oxford University in the U.K. told
The Guardian newspaper,
They infected 22 healthy volunteers with a flu virus. Half of
them had been given the universal vaccine and half were not
"Fewer of the people who were vaccinated got flu than the people who weren't vaccinated," team leader Dr. Sarah Gilbert told the The Guardian, according to
She said a universal vaccine would make it easier to protect
people against the flu.
"It would become a routine vaccination that would be manufactured and used all the time at a steady level. We wouldn't have these sudden demands or shortages -- all that would stop," Gilbert said.
FDA Investigates Early Failure of Jaw Implants
Reports about early failure of some makes of jaw implants are
being investigated by the U.S. Food and Drug Administration.
The agency said the devices made by three companies are expected
to last five years but a "substantial number" of patients have had
to have the implants replaced after three years or less, the
Associated Press reported.
The implants, which connect the lower jaw to the skull, are used
in patients with severe arthritis, injuries or other problems that
limit their jaw movement.
The FDA said it will require the three companies -- Biomet
Microfixation, TMJ Solutions, and TMJ Medical -- to track the life
cycle of the jaw implants, the
After it has gathered more information about the devices, the
agency may recommend changes.
Cholera Confirmed in NYC Residents

to the Dominican Republic last month for a wedding, say health
All three people have since recovered from the disease, a

New Clue About Cause of Age-Related Macular Degeneration
A clue to the cause of age-related macular degeneration (AMD)
may help lead to a cure for one of the leading causes of blindness,
according to an international team of scientists.
They discovered that an enzyme called DICER1 is less active in
the retina of patients with the more common "dry" form of AMD. In
experiments with mice, the team found that turning off the gene
that makes DICER1 resulted in damage to retina cells,
BBC News reported.
Further investigation showed that DICER1 is needed to destroy
small pieces of genetic material called Alu RNA. Accumulation of
this material leads to the destruction of the retina.
