Effective vaccines features o Safety : must not result in infection in the patient o Protective: must protect against illnesses when exposed to live pathogens o Provide prolonged protection o Induce neutralizing antibodies that play a key role in defending against pathogens o Acceptable side effect profiles: Achy, fever o Low cost of production o Ease of storage o Ease of administration Vaccine Types o Attenuated Live viral or bacterial Diminished pathogenecity Both cell mediated and humoral immunity Longer lasting antibody production (advantage) Ability to revert to pathogenic form (disadvantage) o Killed Vaccines (Toxoids) No replicating /non infectious (advantage) Need multiple booster shots (disadvantage) o Recombinant DNA look up Vaccine Development Look up o Passage in cell culture (tissue adaptation) MMR is an example o Species adaptation Small Pox is an example o Temperature selected mutant Influenza Passive Immunization...
