Abstract
Two novel methods of dengue virus inactivation using iodonaphthyl azide (INA) and aminomethyl trioxsalen (AMT) were compared with traditional virus inactivation by formaldehyde. The AMT inactivated dengue-2 virus retained its binding to a panel of 5 monoclonal antibodies specific for dengue-2 envelope protein, whereas inactivation by formaldehyde and INA led to 30-50% decrease in binding. All three inactivated viruses elicited high level virus neutralizing antibodies in vaccinated mice. However, only mice vaccinated with AMT inactivated virus mounted T cell responses similar to live, uninactivated virus.Entities:
