Abstract: COVID-19 continues to wreak havoc on the global population. Infection with SARSCoV-
2 can be mild, severe, and even life-threatening. It is associated with cytokine storm, lung and
even heart damage. With no specific treatment available for this contagious disease, induction of
herd immunity through vaccination is being perceived as the only way out through this pandemic.
Throughout the world, research groups and pharmaceutical companies are working independently or
in collaboration to accelerate the process of COVID-19 vaccine development. Different countries
have already started vaccination drives on a large scale to combat the disease. Today, we have a few
approved vaccines, some are conventional, while others are subunit protein or nucleotide vaccines.
This review describes the various vaccination strategies adopted the clinical and preclinical trials in
developing some of the approved COVID-19 vaccines that are being administered around the world.
The review also focuses on the challenges and adverse effects reported post-vaccination. Some of the
proposed therapies for COVID-19 have also been elucidated. The effectiveness and safety of vaccines
towards SARS-CoV-2 new variants suggest that more research in the field needs to be continued
in the future.
