Covid-19 vaccination: The pros and cons

The advent of Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) also known as COVID-19 disease and the dynamics of its rapid spread around the globe are unprecedented. Different preventive efforts have been undertaken in response to this global health challenge, amongst them, vaccine development, distribution and dispensation is at the forefront. Vaccines stimulate the body’s immune system against infectious pathogens; hence, they are one of the greatest medical accomplishments and a cornerstone of public health. There is a strong consensus globally that COVID-19 vaccine is likely the most effective approach to sustainably controlling the COVID-19 pandemic. An unprecedented research effort and global coordination has resulted in a rapid development of COVID-19 vaccines. Here, we review the various types, Pros (status of different COVID-19 vaccines, their utility in COVID-19 control and as a tool of herd immunity or protection) and Cons (various side effects, leaky vaccination and vaccine hesitancy) of COVID-19 vaccines. Despite all cons it is believed that vaccination will certainly help in building up of herd protection against COVID-19 disease, which could allow lockdowns, travel restrictions and social distancing to be relaxed globally.
