– Covishield, manufactured by Serum Institute of India, is a viral vector vaccine. It uses a modified adenovirus (a common cold virus) to deliver genetic material of the SARS-CoV-2 spike protein into cells, prompting an immune response. It is not an mRNA vaccine.
– Sputnik V, developed by the Gamaleya Research Institute in Russia, is also a viral vector vaccine, using two different adenoviruses (Ad26 and Ad5) for the two doses.
– Viral vector vaccines (like AstraZeneca/Covishield, Sputnik V, and Johnson & Johnson) use a harmless virus to deliver genetic instructions for making the spike protein.
– Inactivated vaccines (like Covaxin, Sinovac, Sinopharm) use killed viral particles.
