COVAXIN ® is included along with immune-potentiators, also known as vaccine adjuvants, which are added to the vaccine to increase and boost its immunogenicity.It is the well-established, and time-tested platform in the world of vaccine technology. Numerous vaccines for diseases such as Seasonal Influenza, Polio, Pertussis, Rabies, and Japanese Encephalitis use the same technology to develop inactivated vaccines with a safe track record of >300 million doses of supplies to date. Why develop Inactivated Vaccine? Conventionally, inactivated vaccines have been around for decades. They contain dead virus, incapable of infecting people but still able to instruct the immune system to mount a defensive reaction against an infection. Inactivated vaccines do not replicate and are therefore unlikely to revert and cause pathological effects. The vaccine is developed using Whole-Virion Inactivated Vero Cell derived platform technology. The indigenous, inactivated vaccine is developed and manufactured in Bharat Biotech's BSL-3 (Bio-Safety Level 3) high containment facility.
