Coronavirus Vaccine in India: In a major fight against COVID-19, India on Sunday approved the emergency use approval of two of the COVID-19 vaccine candidates — Covaxin by Bharat Biotech and Covishield by Serum Insitute of India.
Both Covaxin by Bharat Biotech and Covishield by Serum Insitute of India have got emergency use approvals in India and are likely to roll out soon.
However, people are confused as to which vaccine candidate should they go for if given choice.
Here is the difference between the two vaccine candidates – Covaxin and Covishield:
Oxford and AstraZeneca COVID-19 vaccine, Covishield, is also known as AZD1222. It uses replication and deficient chimpanzee viral vector also called the adenovirus which is based on a weakened version of a common cold virus. It also contains the genetic material of the coronavirus spike protein.
On the other hand, the Covaxin by Bharat Biotech is an inactivated form of the COVID-19 itself. The strain was isolated from an asymptomatic Covid patient at Pune's National Institute of Virology by the Indian Council of Medical Research (ICMR).
The strain was then handed over to Bharat Biotech to produce India's first home-grown vaccine against the novel virus. It uses an inactivated form of the virus to produce an immune response that will counter the virus if it enters the body in the future.
