Are influenza vaccines worth the effort?
Each year enormous effort goes into producing influenza vaccines and delivering them to appropriate sections of the population. But a review of the evidence in this week's BMJ suggests that they may not be as effective as we think.

Oseltamivir significantly reduces the risk of death from influenza
Tamiflu (oseltamivir), is effective in reducing the risk of death associated with seasonal influenza in severely ill patients,1 according to new data presented today. Treatment of infected adults was associated with a 71 per cent reduction in mortality.1 These results demonstrate the importance of the role of antivirals in the management of seasonal influenza and highlights the seriousness and risk of mortality associated with it.

Prisons Unprepared for Flu Pandemic
As the fear of an impending avian flu pandemic is compelling hospitals, businesses and cities to develop preparedness plans, one of the most potentially dangerous breeding grounds of disease is woefully ill-prepared for a crisis, according to a new study being presented today by researchers at Saint Louis University.

Genetic differences between potential pandemic influenza strains outlined
An analysis of H5N1 influenza samples in Southeast Asia shows not only how the two strains that have caused human disease are related but also that they belong to two different, distinct genetic subgroups. Researchers from the Centers for Disease Control and Prevention report their findings today at the International Conference on Emerging Infectious Diseases.

Avian flu virus needs only minor adaptations to infect humans
The H5N1 avian influenza virus, commonly known as "bird flu," is a highly contagious and deadly disease in poultry. So far, its spread to humans has been limited, with 177 documented severe infections, and nearly 100 deaths in Indonesia, Vietnam, Thailand, Cambodia, China, Iraq, and Turkey as of March 14, 2006, according to the World Health Organization (www.who.int).

Influenza-Associated Hospitalization in a Subtropical City
Influenza is estimated to be responsible for a million deaths worldwide every year. In developed countries, epidemics of influenza have long been known to increase hospital admissions and mortality. This impact has been measured quantitatively in many studies dating back over a century. The statistical methods used in such research have involved both �comparative� and, more recently, �regressive� techniques.

FDA Affirms Safety of Tamiflu
The Pediatric Advisory Committee of the U.S. Food and Drug Administration (FDA) has confirmed the safety of Tamiflu (oseltamivir phosphate) in children following a scheduled comprehensive review of data about the use of Tamiflu in children. According to Dr. Robert M. Nelson, chairman of the committee, there is �no concern at all� that Tamiflu played a role in the reported deaths of children with influenza in Japan. Dr. Nelson is an associate professor in the department of anesthesia and critical care at The Children�s Hospital of Philadelphia.

Genomic Data to Help Understand Evolution of Flu Viruses
In the first large-scale effort of its kind, researchers have determined the full genetic sequence of more than 200 distinct strains of human influenza virus. The information, being made available in a publicly accessible database, is expected to help scientists better understand how flu viruses evolve, spread and cause disease. The genomic data already has enabled scientists to determine why the 2003-4 annual influenza vaccine did not fully protect individuals against the flu that season.

What was the Spanish Flu Pandemic?
The Spanish Flu Pandemic, also known as the Great Influenza Pandemic, the 1918 Flu Epidemic, and La Grippe, was an unusually severe and deadly strain of influenza, a viral infectious disease, that killed some 25 million to 50 million people worldwide in 1918 and 1919. It is thought to have been one of the most deadly pandemics so far in human history.

Unmasking the 1918 Influenza Virus
The mysteries of the 1918-1919 influenza pandemic, that killed an estimated 50 million people across the globe, are finally beginning to be solved. Two scientific papers published this week provide insights into the virus that caused the most deadly influenza outbreak in modern history. This virus was unusual because it spread so quickly, was so deadly, and exacted its worst toll among the young and healthy. In just over one year, the virus infected one-third of the world�s population with death rates approximately 50 times higher than those associated with regular seasonal influenza.

Why Spanish flu was so lethal
The 1918 Spanish flu was a global disaster, killing an estimated 20 to 50 million people, many of them otherwise healthy adults. By partially reconstructing the Spanish flu virus, researchers have now discovered at least part of what made the virus so lethal, thus providing essential information for influenza drug and vaccine research.

Researchers Reconstruct 1918 Pandemic Influenza Virus
Influenza pandemics occur when a new strain emerges to which people have little or no immunity. Most experts believe another pandemic will occur, but it is impossible to predict which strain will emerge as the next pandemic strain, when it will occur or how severe it will be.

Inactivated New Human Influenza Vaccine Progressing Through the Pre-Clinical Stage
Current epidemiology shows that H5N1 is highly infectious and pathogenic for birds, but not that serious for humans. However, whenever H5N1 virus combines with human flu virus and both of them recombine to become a new flu virus, then it is possible for that virus to be highly infectious and pathogenic to humans.This kind of pandemic caused by the recombination of human-animal flu virus has historically happened three times. It caused worldwide disaster each time.

Immune cooperation foils influenza A virus infection
Influenza A virus (fluA) is a major human pathogen. The role of certain white bloods cells, known as natural killer (NK) cells, in the innate immune response to fluA is not well understood. In the December 15 issue of the Journal of Clinical Investigation, Xiao-Song He and colleagues from the VA Medical Center in Palo Alto demonstrate that upon exposure of adult cells to fluA, NK cells produce IFN-gamma, which stimulates the immune system to destroy foreign material.
