MAXIMUNE ® 6 is an inactivated oil emulsion vaccine containing three infectious bursal disease viruses, the standard type and two variant strains, and three reoviruses including strain S1133 (a tenosynovitis pathotype), strain 2408 (a malabsorption pathotype) and strain SS412 (a distinct serotype from the S1133 type reoviruses and a causative agent of proventriculitis and malabsorption in broilers). (drugs.com)
The vaccine is indicated for use in healthy breeder replacement chickens and breeder hens against diseases caused by infectious bursal disease viruses (standard and variant types) and reoviruses (standard and SS412 types). (drugs.com)
Optimum results with MAXIMUNE ® 6 require that chickens are adequately primed with live infectious bursal disease vaccine and a tenosynovitis vaccine at least four (4) weeks in advance of administration of the inactivated vaccine. (drugs.com)
The potential vaccine triggers a rapid immune response which protects chickens against signs of disease and reduces the level of virus that they could pass on, a key element to halting the spread of bird flu through flocks. (pirbright.ac.uk)
The vaccine would also be easier and less costly to produce than the traditional flu vaccines made in chicken eggs. (pirbright.ac.uk)
For the first time, researchers at Pirbright have shown that tagging the flu virus haemagglutinin (HA) protein and directing it to target a specific protein on the chicken APCs, called CD83, generates faster and stronger immune responses against the H9N2 bird flu strain compared to the current industry standard inactivated virus vaccine. (pirbright.ac.uk)
The tagged flu virus HA protein can be produced in a laboratory culture of insect cells instead of using eggs to grow live vaccine viruses. (pirbright.ac.uk)
As the new vaccine does not contain live flu virus, biosafety risks are reduced and no specialist high containment facilities would be required for production. (pirbright.ac.uk)
Oxford University Press, 2005, $30.00 April 12 was the day, 50 years ago, that the U.S. Public Health Service licensed the killed-virus vaccine against poliomyelitis developed by Jonas Salk. (technologyreview.com)
Its hero is Albert Sabin - for if any one man conquered polio, it was Sabin, who developed the oral attenuated live-virus vaccine. (technologyreview.com)
While Salk's vaccine did slow down the incidence of polio among middle-class Americans, its cost and its requirement of three injections and a booster meant that for years the disease continued to affect the poor and others lacking access to proper medical care. (technologyreview.com)
Third, the "temperamental" Albert Sabin, who was working on his own vaccine at the University of Cincinnati, sabotaged the killed-virus vaccine. (technologyreview.com)
But by the early 1950s, Sabin and many other immunologists and epidemiologists were convinced that an oral attenuated live-virus vaccine would be more effective. (technologyreview.com)
The question of efficacy was whether any killed-virus vaccine could produce lifelong immunity. (technologyreview.com)
However, if the disease occurs, the vaccine may be able to reduce the risk of severe illness or death. (who.int)
Influenza virus vaccine is used to prevent infection by the influenza viruses. (mayoclinic.org)
