Viral vector vaccines enable antigen expression within cells and induce a robust cytotoxic T cell response, unlike subunit vaccines which only confer humoral immunity. [7] [17] In order to transfer a nucleic acid coding for a specific protein to a cell, the vaccines employ a variant of a virus as its vector.

A 2021 U.S. Centers for Disease Control and Prevention poster on the COVID-19 viral vector vaccines. Viral vectors are modified viruses designed to deliver genetic material into cells. This process can be performed inside an organism or in cell culture. Viral vectors have widespread applications in basic research, agriculture, and medicine.
The Oxford–AstraZeneca COVID-19 vaccine, sold under the brand names Vaxzevria [6] and Covishield, [7] is a viral vector vaccine [8] produced by the British University of Oxford, British-Swedish company AstraZeneca, and the Coalition for Epidemic Preparedness Innovations.
AD5-nCOV, trade-named Convidecia, is a single-dose [2] viral vector vaccine for COVID-19 that is also used as an inhaled booster. It was developed by CanSino Biologics, with Phase III trials conducted in Argentina, [3] Chile, [4] Mexico, [5] Pakistan, [6] Russia, [7] and Saudi Arabia [8] with 40,000 participants.
The List of Prequalified Vaccines, published by the World Health Organization, lists vaccines that are found to be safe, effective and of good quality, after undergoing investigation of relevant data, testing and examination of their production sites. [1] [2] [3] [4]
An mRNA vaccine (or RNA vaccine) is a novel type of vaccine which is composed of the nucleic acid RNA, packaged within a vector such as lipid nanoparticles. [69] Among the COVID-19 vaccines are a number of RNA vaccines to combat the COVID-19 pandemic and some have been approved or have received emergency use authorization in some countries.
