Baxter Study Verifies Inactivation of Influenza H5N1 Virus During Manufacture of Its Plasma-Derived Therapies
Monday March 6, 4:35 pm ET
DEERFIELD, Ill., March 6 /PRNewswire-FirstCall/ -- Baxter Healthcare Corporation today announced the results of a study verifying the successful inactivation of H5N1 influenza (bird flu) virus during the processes routinely used in the production of its plasma-derived therapeutics.
Baxter initiated the verification study to address the rising public concern over the spread of the H5N1 virus outside of Asia, the recent demonstration that the H5N1 virus may occur in blood more widely than other strains of influenza, and the perceived threat of influenza virus transmission through the use of plasma derivatives.
The data were presented at this week's public "Blood Product Safety" conference, organized by Cambridge Healthtech Institute in Baltimore, Md. This presentation of the study coincides with a significantly increased incidence of the H5N1 virus in birds across Europe over the last few weeks.
Study Shows Influenza H5N1 Virus Readily Inactivated
H5N1 influenza is a member of the Orthomyxoviridae family of viruses and is similar in structure to previously identified influenza viruses. As this family of viruses is lipid-enveloped, it was expected that they would be readily inactivated through proven inactivation processes such as pasteurization, vapor heating, low pH and solvent detergent treatment methods.
"Based on available results from other lipid-enveloped viruses, we anticipated that H5N1 influenza would be inactivated during the processing of our plasma-derived therapeutics," said Thomas R. Kreil, Ph.D., director, global pathogen safety for Baxter's BioScience business. "However, we at Baxter acknowledge that users of plasma-derived therapies are especially concerned about any emerging virus, and thus decided to conduct these tests to reassure people who use plasma-derived therapies from Baxter."
This study confirmed that the virus was readily inactivated through one or more of the following methods: pasteurization, vapor heating, low pH and solvent detergent, treatment methods that Baxter employs in the processing of its commercially available plasma derivatives.
About the H5N1 Influenza Virus
Influenza viruses are known by the medical community from significant annual outbreaks, and several pandemic outbreaks involving millions of fatal cases that have occurred in the last century. Currently, the H5N1 influenza virus is spreading out of Asia. Upon infection of humans it has exhibited significant mortality, although it seems that the ability of human-to-human transmission has not yet been acquired by the H5N1 virus.

I worked making Plasma products for 9 yrs, from begining to end product.
They screen all donors (Or supposed too) and freeze the collected plasma for 45 days before release. They check for everything from AIDS to HEP A,B,C and other Dieases.
Then its put into Batches to Thaw -out at the Plant for Processing, then you add the Ingredents to the Batch, a list of stuff that each Manufacture uese in their own Process, to get it to the right Ph of 6.5 to 7.5 is the normal range.
Thats why if any of you ever had a Shot or transfussion of Plasma or another Plasma based substance it either "PAINFUL BURNING or Cold Feeling" depending on the PH LEVEL and products used to cut it with or stablize it for shelf life.
But this is the Strange part
"pasteurization, vapor heating, low pH and solvent detergent treatment methods."
So sounds like to me,their saying, "Hey If you get it we can pump you full of Plasma thats been thru this process to kill the virus."
The Pasteurization process their talking about is a Water bath at +50C (+ OR - 5C) for 11 hrs and 30 mins (+ or minus 20 mins).
The other methods are process related like "Vapor Heating" is Auto Claving"
So it sounds to me like Baxter is going to push "Plasma or "Albumin " as a Bird Flu treatment. Which in the US is given IV and believe or not in Japan and other places "Drank"
<img src=icon_smile_dead.gif border=0 align=middle><img src=newicons/anim_puke.gif border=0 align=middle> I'd be awful <img src=icon_smile_question.gif border=0 align=middle>about this treatment because they still cant say for sure until years down the line,like HIV that it still cant be transferred.HIV when exposed to any temp outside of 98.6F (Human Host) forms a "Shell" and can stay dormant for no-one knows really how long.They say heat Kills it,but during the process everything is pretty well killed the first Hour, the other 10 hours is for "Saftey Sakes and the Hail Mary Pass!"
The only other Real bit of Knowlege I have in the world,since I dont Build Clocks or Fix Hogs anymore.
