answer question B, page 71
- DNA vaccines began in the 1990s, but they are not widely available today because virtually all still remain in clinical trials
- DNA vaccines do not contain a live virus, so one cannot get sick from them, whereas other vaccines pose that risk
- They prompt helper T cells and B cells to multiply and create memory cells and activate cytotoxic "killer" T cells, which builds Answers will vary. long-lasting immunity
2 In general, genetic material from the virus or bacteria is used to elicit an immune response. Scientists first isolate the gene from a target pathogen and then splice it into a double-stranded DNA vector
- They may disrupt cellular processes and produce anti-DNA antibodies, resulting in too-low levels of immunogenicity
