- Pfizer: The Pfizer-BioNTech COVID-19 vaccine is an mRNA vaccine. This match is correct. 2. Covishield: Covishield is the name for the Oxford– AstraZeneca COVID-19 vaccine manufactured by the Serum Institute of India. It is a viral vector vaccine, using a modified chimpanzee adenovirus to deliver genetic material. While the vector carries DNA instructions for the spike protein, classifying it solely as a "DNA based vaccine" is less precise than "viral vector vaccine" and can be considered incorrect in the context of standard vaccine types which distinguish between direct DNA injection and viral vector delivery. 3. Covaxin: Covaxin, developed by Bharat Biotech, is an inactivated whole virus vaccine. It uses SARS-CoV-2 virus that has been chemically inactivated so it cannot cause disease. This match is correct. 4. Sputnik V: Sputnik V, developed by the Gamaleya Research Institute in Russia, is a viral vector vaccine using two different adenovirus vectors (Ad26 and Ad5). This match is correct. 140. Covaxin, India's indigenous COVID-19 vaccine, was developed by : I. Bharat Biotech II. Serum Institute of India Pvt. Ltd. III. Pharmacy Council of India – AstraZeneca IV.
