Pandemic Flu, Like Seasonal H1N1, Shows Signs Of Resisting Tamiflu
If the behavior of the seasonal form of the H1N1 influenza virus is any indication, scientists say that chances are good that most strains of the pandemic H1N1 flu virus will become resistant to Tamiflu, the main drug stockpiled for use against it…
Dry Winters Linked To Seasonal Outbreaks Of Influenza
The seasonal increase of influenza has long baffled scientists, but a new study published this week in PLoS Biology has found that seasonal changes of absolute humidity are the apparent underlying cause of these wintertime peaks. The study also found that the onset of outbreaks might be encouraged by anomalously dry weather conditions, at least in temperate regions…
Pandemic Hybrid Of Bird And Human Seasonal Flu Possible Say Scientists
An international team of scientists has created a highly pathogenic laboratory hybrid of the H5N1 bird flu and human seasonal flu viruses by swapping just one gene, and propose that a similar genetic interaction could happen in nature between the current pandemic H1N1 swine flu and H5N1 avian flu strains, highlighting the importance of continued surveillance…
WHO Recommends H1N1 Be Added To Next Year’s Seasonal Flu Virus
The WHO is recommending the H1N1 (swine flu) virus be added to the regular flu vaccine for the Northern Hemisphere’s 2010-2011 regular flu season, the Associated Press reports (2/18). The recommendations, announced Thursday, came after a “closed-door four-day meeting” of WHO influenza experts, Reuters reports…
High Dose Seasonal Influenza Vaccine Specifically Intended For People Ages 65 And Older Approved By U.S. FDA
The U.S. Food and Drug Administration today approved Fluzone High-Dose, an inactivated influenza virus vaccine for people ages 65 years and older to prevent disease caused by influenza virus subtypes A and B. People in this age group are at highest risk for seasonal influenza complications, which may result in hospitalization and death…
H1N1 more risky than seasonal flu in children with sickle cell disease
Infection with the H1N1 virus, or swine flu, causes more life-threatening complications than seasonal flu in children with sickle cell disease, according to new research. The findings warn parents and caregivers that such children are more likely to need emergency treatment and stays in an intensive-care unit.
Previous Seasonal Flu Infections May Provide Some Level Of H1N1 Immunity
Researchers at the La Jolla Institute for Allergy & Immunology have found that previous influenza infections may provide at least some level of immunity to the H1N1 “swine” flu. “The question we asked was, “Is the swine flu more like the seasonal flu or like a totally new strain of influenza where there would be no immunity?,” said Alessandro Sette, Ph.D., an internationally recognized vaccine expert and director of the La Jolla Institute’s Center for Infectious Disease.
FDA Expands Use Of CSL Limited’s Seasonal And H1N1 Vaccines To Infants And Children
The U.S. Food and Drug Administration has approved the use of the CSL Limited’s seasonal and 2009 H1N1 influenza vaccines to include children ages 6 months and older. These vaccine were previously approved for use in adults, ages 18 years and older “Because children are among those most vulnerable to the 2009 H1N1 virus, having a broader range of vaccines available for use in children is an important step in responding to the H1N1 outbreak,” said Margaret A. Hamburg, M.D.
Could Vaccination For Children Against Seasonal Flu Stop Immunity Developing Against Pandemic Strains?
Infection with “seasonal” influenza A could actually benefit children by giving them improved immunity against pandemic strains such as the swine flu H1N1 strain now circulating. Thus, vaccinating children aged 6 months to 5 years against seasonal flu, as is recommended in some countries, could be disadvantageous to these children.
