Question
Covishield uses a ______ in its COVID-19 immune response mechanism.
a. mRNA
b. Protein subunit
c. Viral vector
d. Synthetic molecule
Solution
Break Down the Problem
- Identify the type of vaccine Covishield is.
- Determine which option correctly describes the mechanism it uses for immune response.
Relevant Concepts
Covishield is known as a viral vector vaccine, which uses a modified version of a virus to deliver genetic material into cells, prompting an immune response without causing disease.
Analysis and Detail
Covishield, specifically developed by AstraZeneca, uses a weakened version of a common cold virus (adenovirus) that is not capable of replicating in humans. This viral vector is engineered to contain instructions for making a part of the spike protein of the SARS-CoV-2 virus, leading to an immune response.
Verify and Summarize
The correct mechanism used by Covishield fits the definition of a viral vector vaccine.
Final Answer
Covishield uses a c. Viral vector in its COVID-19 immune response mechanism.
