Griffith studied Streptococcus pneumoniae in 1928 intending to develop a vaccine. Griffith cultured Streptococcus pneumoniae in the laboratory and discovered two strains, the R strain, and the S strain. These strains varied in their virulence or ability to cause disease. Griffith injected both S and R strains into mice. Based on the results of Griffith's experiments, which of the following is incorrect?
