One well-studied example comes from the comparison of wild-type and vaccine strains of poliovirus. It was clearly shown that virulent and attenuated viruses differed in only a small number of nucleotides. Infectious genomic cDNA constructs containing different combinations of wild-type and vaccine ...

What is a normal titer level? The normal values of an antibody titer depend on the type of antibody. If the testing is done to detect autoantibodies, the normal valueshould essentially be zero or negative. In the case of testing the efficacy of a vaccine, the normal test result depends on...
