How do vector vaccines work to provide immunity?

By introducing a weakened or inactivated virus into the body

By directly attacking and destroying pathogens in the body

By placing the virus in a modified version of a different virus

By entering directly into the cells and enabling them to create spike proteins

Solution

Correct option is C

Vector vaccines use a modified version of a different virus (the vector) to deliver important instructions to cells. For example, the viral vector can carry genetic material that instructs the cells to produce a harmless piece of the target virus, such as the spike protein in the case of COVID-19 vaccines. Once the immune system recognizes the spike protein, it triggers an immune response, preparing the body to fight the real virus if encountered in the future.
