What is the basic principle of vaccination? How do vaccines prevent microbial infections? Name the organism from which the hepatitis B Vaccine is produced.
Answers (1)

Antibodies are created by the body in response to the vaccine, and these antibodies jump into action when the pathogen attacks again. Yeast is used to producing the Hepatitis B vaccine.
