∙ 15y agoFrom the Centers for Disease Control and Prevention (CDC): RECOMBINANT VACCINES Vaccine antigens may also be produced by genetic engineering technology. These products are sometimes referred to as recombinant vaccines. Three genetically-engineered vaccines are currently available in the United States. Hepatitis B vaccines are pro- duced by insertion of a segment of the hepatitis B virus gene into the gene of a yeast cell. The modified yeast cell produces pure hepatitis B surface antigen when it grows. Live typhoid vaccine (Ty21a) is Salmonella typhi bacteria that has been genetically modified to not cause illness. Live attenuated influenza vaccine (LAIV) has been engineered to replicate effectively in the mucosa of the nasopharynx but not in the lungs.

Definition of the conventional vaccines?
Conventional vaccines consist of whole pathogenic organisms, which may either be killed or live vaccines; the virulence of pathogens is greatly reduced in attenuated vaccines. This is classified into 2 categories :a)Live or attenuated vaccines; (eg : BCG vaccine)b)Inactivated vaccines (eg : Salk polio & Pertussisvaccines)
