Q. Which of the following statements is/are correct about the term ‘bivalent vaccines’ often seen in the news?
Select the correct answer using the code given below:
The correct option is A 1 only
Explanation:
Statement 1 is correct: A bivalent vaccine works by stimulating an immune response against two different antigens, such as two different viruses, e.g. Cervarix vaccine protects the body against infection with two different types of human papillomaviruses (HPV).
Statement 2 is incorrect: Several types of multivalent vaccines are made using whole bacteria or virus, or parts of them, often a protein or sugar. These antigens trigger an immune response when in the body. Live attenuated bacteria have great potential as multivalent mucosal vaccines against a variety of pathogens.
