No vaccine for the flu mutation H5H1

RFA 08.30.2011
The virologists yesterday warned no vaccine against the mutant strain of H5N1 bird flu virus is widespread in Vietnam and China, and called for strict supervision to prevent epidemic spread to humans.

The call was made after the Food and Agriculture Organization (FAO) UN warning on Monday about the possibility of avian flu back and the new variant is widespread in Asia and far more.
Currently scientists are not sure whether the new strain H5N1-2.3.2.1 is more dangerous in people or not, but it certainly is different from previous strains of virus to escape vaccine against H5N1 in humans.
It is known that H5N1 began to reemerge in recent months. Most notable is the 8 people in Cambodia died from H5N1 infection this year.
FAO said that Vietnam now has stopped vaccinating poultry for years, and new variants appear mainly in northern and central provinces.
