You have joined a research lab that is testing new vaccines for a new strain of the influenza A virus (IAV). The lab's prior studies have shown that when C57BL/6 laboratory mice are given non-pathogenic bacteria that have been engineered to express a 16 amino acid peptide, after about a month the mice produce IgG antibodies that effectively neutralize IAV. Your project is to test serum samples from healthy adult humans who were given these bacteria 6 weeks ago as...
