COVAXIN AND COVISHEILD

Covaxin is an inactivated vaccine that has been developed by Hyderabad-based Bharat biotech international limited in collaboration with the Indian council of medical research(ICMR) and the National Institute of Virology, Pune. it is based on tried and tested platform of dead viruses(The whole virion inactivated Vero cell technology)

The vaccine is developed using whole virion inactivated Vero cell-derived platform technology. inactivated vaccines do not replicate and are therefore unlikely to revert and cause pathological effects. They contain dead viruses incapable of infecting people but still able to instruct the immune system to mount a defensive reaction against an infection.
Efficiency: 81%

Covisheild is based on the viral vector platform. A chimpanzee adenovirus called ChAdOx1 is the vector that has been modified to carry the coronavirus spike protein in human cells. While the injected cold virus is harmless it serves as an instruction manual for the body on how to fight against similar viruses. This platform is used for injections like ebola.
Efficiency: 70%

Storage temperature: 2-8 C
