Lakewood-Amedex 's nRNA product works by selectively silencing targeted genes in the viral genome . The company is building on the previously successful animal model study where mice infected with H1N1 type A influenza virus were given two doses of the L-A nRNA product and all survived while control and placebo dosed mice all died within six days . In addition L-A previously published a study demonstrating the effectiveness of its technology against the lethal H5N1 " bird flu " influenza virus in which a single intra-nasal dose of the company 's nRNA product protected 100 % of the infected chickens while placebo treated chickens all died within seven days .
