(a) 1 and 2 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3


Answer: (b)

Explanation:

Covishield

  • Covishield vaccine is based on the platform which uses a recombinant, replication-deficient chimpanzee adenovirus vector encoding the SARS-CoV-2 Spike (S) glycoprotein.
  • The Serum Institute of India produced a COVID-19 vaccine named Covishield but not using mRNA platform.
  • It has been prepared using the viral vector platform. In the vaccine, a chimpanzee adenovirus – ChAdOx1 – has been modified to enable it to carry the COVID-19 spike protein into the cells of humans.
  • This cold virus is basically incapable of infecting the receiver, but can very well teach the immune system to prepare a mechanism against such viruses. Statement 1 is incorrect.

Sputnik V

  • It is the world’s first registered vaccine based on a well-studied human adenovirus vector platform. Statement 2 is correct.

Covaxin

  • Covaxin is an inactivated viral vaccine – Statement 3 is correct.
