There are concerns from scientists on the recently rolled out vaccine.We are in a world where everything, more so in the field of science is guided by systematic set of mechanisms, methods and metrics.It is important that all phases of trials are extensively carried out and the findings of the studies done on vaccine are available to the world and are peer reviewed. Unless the vaccine is administered to people across wide range of conditions including pre morbidities, its efficacy may not be established totally. For example, a phase II clinical trial of a Covid-19 vaccine published is said to have excluded obese people ,pregnant women and those with chronic diseases.But all such groups have to get vaccine in future .
Enough testing of safety and effectiveness of its working in a general population along with information on dosage and vaccine schedule all form an integral part in the process.Extensive trials on animals, then extended to humans gradually increasing the number with periodic assessments, publication of results, peer reviewing by international scientific community, form the essential sequence of steps in the roll out of a product and its acceptance.
The intention to produce an early vaccine is appreciable but it should be with stricter compliance of the needed norms. Also the sample size should be as large as possible to add further strength to the validity.The procedure of enrolment of volunteers that forms a major part of the Herculean exercise especially in large numbers, the needed protocols, administrative procedures all can be accelerated simultaneously when the preparation of vaccine is going on so the that the overall time frame can be downsized.
