In April 2009, public health surveillance detected an increased number of influenza-like illnesses in Mexico City's hospitals. The etiological agent was subsequently determined to be a spread of a worldwide novel influenza A (H1N1) triple reassortant. The purpose of the

The objectives of this study were to: (1) reflect on key stages in the discovery, development and pre-pandemic use of neuraminidase inhibitors (NAIs), (2) summarise the evidence of NAI effectiveness for treatment and prophylaxis of seasonal influenza prior to the

Few questions on infectious disease are more important than understanding how and why avian influenza A viruses successfully emerge in mammalian populations, yet little is known about the rate and nature of the virus' genetic adaptation in new hosts. Here

In 2009, we successfully produced a high-yield live attenuated H1N1pdm A/California/7/2009 vaccine (CA/09 LAIV) by substitution of three residues (K119E, A186D, and D222G) in the hemagglutinin (HA) protein. Since then, we have generated and evaluated additional H1N1pdm vaccine candidates from

Journal of virology, 87(9), 5161-5169 (2013-03-02)
Influenza virus is well recognized to modulate host tropism and pathogenesis based on mutations in the proteolytic cleavage site of the viral hemagglutinin (HA), which activates HA and exposes the fusion peptide for membrane fusion. Instead of the conventional trypsin-mediated
