The emergency approval of Pfizer BioNTech Covid19 vaccine is a remarkable step against war against Covid19 says Dr Subhrajyoti Bhowmick, Clinical trial Expert  

“The emergency approval of Pfizer BioNTech Covid19 vaccine is a remarkable step against war against Covid19. The vaccine has been approved keeping in consideration that the initial efficacy analysis had shown over 90 percent efficacy in preventing Covid19 infection among the healthy volunteers.
We need to understand that this is an emergency authorization and the vaccine safety and efficacy data will be kept under observation even after the approval. Incase either of it is found not acceptable in the larger population, the emergency authorization can be revoked as well”, said Dr Subhrajyoti Bhowmick,  Clinical trial specialist and clinical Pharmacologist & Director, Clinical Research  Peerless Hospital, Kolkata
