In December 2019 there was an information emerged about the “respiratory illness”. Immune system is basically comprised of collection of various cells, different processes, and chemicals which constantly defends the body against invading pathogens, which includes viruses, bacteria and other toxins. Keeping the immune system healthy and strong year-round is the key to prevent infection and diseases. Due to the pandemic there was an increased medical risk all over the world which was mainly related to covid-19. Due to limited and decreased supply, few countries are planning to mainly maximize the immunity of the population thereby postponing the second dose of the vaccines and for the same reasons and new vaccine trials are being assessed, mix and match schedules which in turn administer different vaccine products to the same individual. Though vaccines have not cleared all the phases of clinical trials vaccines may also cause the adverse events which may be temporary or maybe life threatening also. The main objectives of vaccination includes reduction of pressure on health care system, reduction of overall covid-19 mortality and severity, reopening of society and disease elimination. Therefore vaccines can be sustainable, continual and feasible solution to the covid-19 pandemic.
