COVID -19, covishield, covaxin, vaccination, India


After the devastating second wave of COVID-19, with the rapid increase in the number of new cases in many states of India marking the beginning of a probable third wave of COVID-19, our best bet is taking a jab to protect against COVID-19. Currently, licensed vaccines are found to be reasonably safe and effective. The second wave of COVID-19 was devastating, but it's a silver lining to note that most of the individuals who had taken the jab recovered with mild infections, and the hospitalization rates among jabbed individuals were meager.  Various rumours related to the efficacy, safety, content, and side effects of the vaccine in India had caused a plunge in the vaccine acceptance rate leading to hesitancy and carelessness among the Indian population. This is a critical time for facts, not fear or rumors. This review provides an insight into the myths, pros and cons, and efficacy of the available vaccines.
