The DCGI has stated that a COVID-19 vaccine candidate ought to have no less than 50 per cent of efficacy within the Phase-III medical trial for it to be extensively deployed and enough knowledge informing the potential danger of vaccine-associated Enhanced Respiratory Disease (ERD) must be generated.
The complete draft regulator guideline for the event of a vaccine with particular consideration for the COVID-19 vaccine gives steering to the vaccine builders to make sure that vaccines are well-characterised and manufactured constantly.
The steering reads that contemplating the pressing want for a secure and efficient vaccine for prevention of COVID-19, medical growth applications of the COVID-19 vaccine could proceed via an adaptive and seamless method together with knowledge to tell the potential danger of vaccine-associated ERD shall be wanted.
The doc has highlighted that the usage of COVID-19 preventive vaccines in being pregnant and in ladies of childbearing potential is an important consideration for vaccination applications.
“There are three things for a vaccine–(i) the safety, (ii) immunogenicity, and (iii) the efficacy. Even, WHO says that if we can get more than 50 per cent efficacy that is an accepted vaccine. For respiratory viruses, we never get 100 per cent efficacy. We are aiming for 100 per cent efficacy but may get 50-100 per cent,” Dr Balram Bhargava, ICMR, Director-General stated on Tuesday whereas responding to a question on the efficacy of COVID-19 vaccine.
