The coronavirus disease 2019 (COVID-19) pandemic has accelerated scientific innovation in vaccine development to an unprecedented pace. Within one year of the identification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), multiple vaccines received emergency use authorization. The introduction of mRNA vaccines, viral vector vaccines, protein subunit vaccines, and inactivated virus vaccines has reshaped immunization strategies worldwide.
Despite remarkable success in reducing hospitalizations and deaths, significant challenges remain, including waning immunity, the emergence of immune-evasive variants, inequitable vaccine distribution, and vaccine hesitancy. This paper reviews the development of COVID-19 vaccines, analyzes their safety and efficacy profiles, explores challenges in implementation, and discusses future perspectives, including next-generation vaccines and global preparedness for future pandemics.
