I found an article on cnn.com yesterday saying they've created a vaccine against the bird flu. http://www.cnn.com/2006/HEALTH/02/02/birdflu.vaccine.reut/in dex.html please read the article and submit any comments you have on it. do you think they've really created a useful vaccine? |

I'm sure they have already in some form or another for the time being for a particular strain. What they have of it will probably all go to the military. Normal people will not see any vaccine for a year or more if we're lucky. Prepare to ride it out anyway. |

Speculation is the only tool we have with a threat that can circle the globe in 30 days. Test results&news is slow.Factor in human conditions,politics, money&bingo!The truth!Facts come after the fact.

Most excellent. Hope then can make it fast enough, in sufficient quantities, and available to all. LOL!

Experts Skeptical of Experimental Birdflu Vaccines USA: February 6, 2006 WASHINGTON -" Two teams working on better vaccines for use against a potential bird flu pandemic have announced progress in the past week, but influenza experts are skeptical. The two labs both used a human cold virus, called an adenovirus, to carry pieces of DNA from H5N1 flu in a vaccine. Both labs - one at the US Centers for Disease Control and Prevention and one at the University of Pittsburgh Medical Center - were able to protect mice against fatal H5N1 infections. But neither study was even mentioned at a meeting of top US flu experts in Washington this week. "It's just not that new," Dr. John Treanor, a flu vaccine expert at the University of Rochester in New York, said in an interview. "There are a zillion vaccines that protect in mice. On the grand scale of things, it's nowhere near to being a vaccine you would see in humans." But developing new vaccines is a time-consuming and tricky business, and for the next few years the world is stuck with 40-year-old technology, no matter what happens in the lab, the experts, including manufacturers, said. Researchers rely on an old-fashioned way of making vaccines against influenza that requires the use of chicken eggs and months of cultivation. Several companies and private labs are working on a vaccine against H5N1. But because no one knows how it will mutate, they cannot be sure that any vaccine made now would protect against whatever pandemic strain eventually emerges. Vaccines using cold viruses, using pure DNA, and using whole inactivated viruses are all being tried. But because they use completely novel technology, they would have to be extensively tested in humans, who have different immune responses from other animals. Chris Viehbacher, President of GlaxoSmithKline, which makes flu vaccines, said it would take years to approve entirely new approaches to flu vaccine. If a pandemic comes before vaccine technology can be improved, Glaxo had counted on using the current vaccine formulation boosted with an aluminum adjuvant, he said in an interview on Tuesday. Adjuvants are added to vaccines to help increase the immune response and may make it possible to stretch a vaccine supply. Before boosting production and building new plants in the United States, Viehbacher said drug makers wanted better protection from lawsuits from people who may be harmed, or who may claim they were harmed, by vaccines." http://www.planetark.com/dailynewsstory.cfm/newsid/34875/ story.htm]http://www.planetark.com/dailynewsstory.cfm/newsi d/34875 Edited by Rick |

I saw this too. And I'm very hopeful. However, this recombinant technology has been around for quite a while now. My understanding is that they introduced the gene for haemagluten from H5N1 into an adenovirus. They grow the adenovirus in a cell/tissue culture (very fast) and then the adenovirus is either 1) used to infect a person causing a common cold but confering some immunity to the haemagluten inserted or 2) destroyed but leaving all the viral DNA intact leading to a naked DNA vaccine that will confer immunity to the haemagluten. Seems logical.... but I'm somewhat suspicious of the timing. If I've got hte technicals wrong I'd love to be corrected. John.
