INFLUENZA A (H1N1) – SWINE IMMUNITY

A ProMED-mail post (May 28, 2009)

The following is [1] a statement of the research program of the United States Department of Agriculture (USDA) Agricultural Research Service (ARS), and [2] the outcome of a study of the cross-reactivity of serum samples from US pigs against the new swine origin 2009 H1N1 influenza virus (S/O H1N1).

And is there any way to ensure that people around the world have an equal chance to get the new vaccine? Continue reading Devilish Dilemmas Surround Pandemic Flu Vaccine

The major determinant of the severity of an influenza pandemic, as measured by the number of cases of severe illness and deaths it causes, is the inherent virulence of the virus. However, many other factors influence the overall severity of a pandemic’s impact. Continue reading Assessing the Severity of an Influenza Pandemic
