In a recent study of influenza virus reassortment in ferrets, the authors used polymerase chain reaction (PCR) to search for viruses with RNA segments from the 2009 pandemic H1N1 strain and seasonal H1N1 and H3N2 strains. I thought you might like to see how I did a similar experiment in ...

An Australian group has reported results of a clinical trial to determine the safety and immunogenicity of a 2009 pandemic H1N1 influenza virus vaccine. Twenty-one days after the first of two scheduled doses, the vaccine proved to be immunogenic in adults. This is good news, as many had believed that ...

When more than one influenza A virus subtype is circulating in humans, as has been the case since 1977, there are several possible outcomes. The viruses might co-circulate, one virus might out-compete another, or co-infection of cells with two viruses can lead to the production of genetically distinct viruses by ...

Of the many questions that I receive about influenza, one of the most common is "when will swine flu return to the US?". In other words, when will the 2009 pandemic H1N1 strain, first recognized in humans in April 2009, emerge for the 2009-2010 influenza season? "Return" is probably not ...
