A Comprehensive Review of mRNA-based Vaccines for COVID-19, A New Era in Pharmaceuticals: Unspecified and Unknown Aspects, Effects and Challenges.

Ongoing research and development efforts are currently focused on creating COVID-19 vaccines using a variety of platforms. Among these, mRNA technology stands out as a cuttingedge method for vaccine development. There is a growing public awareness of mRNA and its potential in vaccine development. Despite being relatively recent, extensive scientific research has been dedicated to vaccines for a considerable period. mRNA vaccines are created by synthesizing the spike protein from a DNA template. This review delves into the various aspects of these vaccines and thoroughly explores the intricacies of COVID-19 vaccinations. It is essential to choose a reliable, efficient, and widely accessible vaccine to combat COVID-19. However, due to the possibility of virus mutations, developing a dependable and safe vaccine is crucial to prepare for future outbreaks of SARS-CoV-2 variants. Meanwhile, concerns remain regarding the potential risks associated with these vaccines.
