Biology - Human Health and Diseases Question with Solution | TestHub
Given below are two statements about vaccines.
Statement (I): Vaccines provide natural acquired active immunity.
Statement (II): The latest hot spot in the field of vaccine research is the development of oral vaccines.
In light of the above statements, choose themost appropriateanswer from the options given below.
Options:
Answer:
Solution:
Statement (I) is incorrect because vaccines provide artificially acquired active immunity, not naturally acquired active immunity. Naturally acquired active immunity is developed when an individual is naturally exposed to a live pathogen and develops a primary immune response.
Statement (II) is incorrect because the latest hot spot in the field of vaccine research is the development of edible vaccines (and DNA/mRNA vaccines), not oral vaccines in general. Oral vaccines, such as the Oral Polio Vaccine (OPV), have already been in use for several decades.
Therefore, both Statement (I) and Statement (II) are incorrect.
Answer: Both Statement (I) and Statement (II) are incorrect.
