Abstract

The availability of different vaccines plays a crucial role in bringing the COVID-19 pandemic to a standstill. All the vaccines with two initial and a booster dose have reduced the mortality rate and do not elicit serious symptoms or illness. However, the clinical trials on different vulnerable populations are still not reliable. In particular, COVID-19 patients belonging to the diabetic population exhibited higher morbidity and mortality. Therefore, the prioritization of vaccination for these populations may reduce further complications. Yet, the hesitancy toward vaccines hinders the process of vaccination campaigns. Hence, this review focuses on the availability of different vaccines against COVID-19 and their role in eradicating previous epidemics. The effect of this vaccination on the diabetic group and the management of chronic illness have been emphasized.
