Is pre vaccination the reason for less morbidity and mortality for COVID-19 in India: an epidemiological study

Abstract

As we all know the current rapid  of the  covid-19  in the most of the world has become a pandemic situation. Many research studies have been  by various countries to develop a  vaccines against the coronavirusSARS-CoV-2. Currently about   six vaccine candidates have passed early testing and have entered the clinical trials across the globe, along with  more than80 other candidates reported to be in preclinical stages. This state that many different approaches are being moved forward at the same time. However, the destinationis not yet completed and so  no vaccines are currently licensed for any of the other coronaviruses affecting humans. If we go in the past few decades, various vaccines were given to geriatrics as well as paediatrics. So if we look the same in other countries the use of the vaccines is very less or instead some countries have no authentic grant to sell or use the vaccines. Here in this present study we are trying to propose that by the early use of the vaccines  also reduced the number of reported COVID-19 cases in a country. So is the combination of these vaccines a reason for the reduced morbidity and mortality and can it be  a boon to fight against the disaster of COVID-19  in future.
