At the start of 2021, two COVID vaccines have received approval for emergency use in India. The review of study data available on the safety and efficacy of these vaccines, and understanding their technological development along with rational of their approval, can help in achievement of a more effective vaccination drive. It is important at this stage that apprehensions and concerns on these vaccines are addressed scientifically in a balanced manner to improve vaccination coverage and success.

At the start of 2021, two COVID vaccines have received approval for emergency use in India. The review of study data available on the safety and efficacy of these vaccines, and understanding their technological development along with rational of their approval, can help in achievement of a more effective vaccination drive. It is important at this stage that apprehensions and concerns on these vaccines are addressed scientifically in a balanced manner to improve vaccination coverage and success.
