So that&#8217;s what drug makers used last year in ramping up a new vaccine to offer protection from the sudden spread of the H1N1 virus.<\/p>\n<p>But &#8220;the response to H1N1 was a disaster,&#8221; said Brett Giroir, vice chancellor for research at Texas A&#038;M University System, says in a <a href=\"http:\/\/online.wsj.com\/article\/SB10001424052748703503804575083611168442980.html\" >WSJ report<\/a> this morning on an unusual plan to use tobacco plants to make flu vaccines. That&#8217;s a technician soaking a tobacco plant in bacterial solution to make a plant-based vaccine in the picture.<\/p>\n<p>Texas A&#038;M is part of a consortium getting $40 million from the U.S. Defense Department to test plant-based vaccines and to produce an initial 10 million doses to combat H1N1, otherwise known as swine flu. The consortium will invest another $21 million in the project known as GreenVax, which is being announced today, the Journal says.<\/p>\n<p>There have been numerous approaches to try to improve vaccine production in recent years, including a new Novartis plant in North Carolina that is growing flu viruses in vats of cells <a href=\"http:\/\/online.wsj.com\/article\/SB125911113742763271-search.html\" >derived from dog kidneys<\/a>. But animal parts can contain pathogens harmful to humans. <\/p>\n<p>Using plants is an alternative, with tobacco proving especially attractive because it&#8217;s cheap to grow and can yield large amounts of vaccine in a matter of weeks instead of several months under the egg method, the WSJ says. It also cites other plant-based work going on at Arizona State and by Germany&#8217;s Bayer.<\/p>\n<p>The military is backing the GreenVax project because it was unnerved by <a href=\"http:\/\/online.wsj.com\/article\/SB125623425595101755-search.html\" >delays in producing<\/a> the H1N1 vaccine and it wants a more sure-fire way to protect soldiers from infectious diseases, not to mention bioterrorist threats. The Pentagon is also trying to tell when soldiers are <a href=\"http:\/\/online.wsj.com\/article\/SB10001424052748703294004574511602782800232-search.html\" >getting a cold<\/a> before they go into combat.<\/p>\n<p><strong>Pandemic update:<\/strong> World Health Organization experts decided today it is too soon to say swine flu has peaked so it&#8217;s still officially a pandemic.
