Recombinant vaccines

Definition

Recombinant vaccines are created using recombinant DNA technology, where specific genes from a pathogen are inserted into another organism to produce the desired antigen. These vaccines provoke an immune response without using live pathogens.

5 Must Know Facts For Your Next Test

1. Recombinant vaccines do not contain live pathogens, reducing the risk of infection.
2. These vaccines often use yeast or bacterial cells to produce antigens.
3. The Hepatitis B vaccine is a common example of a recombinant vaccine.
4. They can be tailored to target specific proteins of a pathogen for more effective immunization.
5. Recombinant vaccines are generally considered safe for immunocompromised individuals.
