Recombinant vector vaccines are developed using genetic engineering techniques. A gene from the target pathogen (e.g., the spike protein gene of SARS-CoV-2) is inserted into the genome of a harmless vector organism (usually a virus or bacterium). This process involves genetic manipulation.<br \/>\n&#8211; Statement 2 is correct. Both viruses (e.g., adenoviruses, vaccinia virus) and bacteria (e.g., attenuated Salmonella, Listeria) are used as vectors in the development of recombinant vector vaccines. The vector delivers the pathogen&#8217;s genetic material into host cells to trigger an immune response.<br \/>\n<\/section>\n<section id=\"pyq-additional-information\">\n&#8211; Recombinant vector vaccines are one of the modern approaches to vaccine development. They combine elements of traditional vaccine approaches with genetic engineering, offering advantages in terms of safety and the ability to elicit strong immune responses.
