Question

One current COVID-19 vaccine candidate being tested is using a replicating nonvirulent measles virus with the SARS-CoV-2 spike protein. What type of vaccine platform best describes this?  

		DNA vaccine
		Subunit or acellular vaccine
		Inactivated vaccine
		Recombinant-vector vaccine

Answer 1

recombinant vaccine is the answer.

In this case, the non virulent measels virus DNA is combined with SARS Cov 19's spike protein DNA gene. Hence there is found expression of spike protein in measles virus. The such measles virus is known as recombinant measles virus.

The non-violence train is injected in the body. The body will start making antibody against the spike protein. That's why in future, when the SARS CoV-19 virus will infect body, then the recovery rate is high in in such individual.
