Nine COVID-19 Vaccines Available Worldwide

According to various governmental agencies, there are nine COVID-19 vaccines available globally. As of January 31, 2021, the COVID-19 vaccine development landscape includes innovative platforms such as DNA, RNA, virus-like particle, peptide, viral vector, recombinant protein, live attenuated virus, and inactivated virus approaches.

These innovative vaccines were initially developed in countries such as China, Germany, Russia, the United Kingdom, and the USA.

The latest COVID-19 vaccine to launch significant in-country distribution is the EpiVaxCorona vaccine produced in Russia. EpiVacCorona is an antigens-based vaccine that provokes an immune reaction against COVID-19 and promotes the further development of immunity.

Furthermore, from a total number of completed vaccinations, media reports indicate the Pfizer-BioNTech co-developed Comirnaty vaccine is the leader. Comirnaty is a nucleoside-modified RNA formulated in lipid nanoparticles and encodes an optimized SARS-CoV-2 full-length spike protein antigen.

Moreover, several experimental COVID-19 vaccines are approaching competition of their phase 3 studies, such as Johnson & Johnson. This news indicates the world will have additional COVID-19 vaccines available to choose from during 2021.
