SummaryThe COVID-19 vaccine developed by BioNTech and Pfizer is known as BNT162b2 (Comirnaty). BNT162b2 contains messenger RNA, or mRNA, from SARS-CoV-2. SARS-CoV-2 is the virus responsible for COVID-19.

Although development timelines for vaccines against SARS-CoV-2 were much quicker than standard vaccine development timelines, regulatory requirements for efficacy and safety evaluations, including the volume and quality of data collected, were upheld. Rolling review processes supported by sponsors and regulatory authorities enabled rapid assessment of clinical data as well as emergency use authorization.

This was clearly demonstrated during the COVID-19 pandemic where regulators and industry rapidly adapted to ensure continued supply of existing critical medicines and review and approve new innovative medicines. In this retrospective study, we analyze the impact of regulatory agilities on the review and approval of Pfizer/BioNTech's BNT162b2 mRNA COVID-19 Vaccine globally using regulatory approval data from 73 country/regional approvals.

In response to the emergence of Omicron sub-lineages, variant-adapted vaccines that contain or encode for Omicron spike protein components have been developed.

Within less than a year after COVID-19 was declared a pandemic, vaccines had received emergency approvals and vaccination campaigns were initiated.
Areas Covered: We discuss the several factors that led to the unprecedented, accelerated development and approval of COVID-19 vaccines, which includes optimization of processes by regulatory authorities, redesign of sequential development processes, learnings from previous pandemics, and prior development of novel vaccine platforms.
The International Alliance for Biological Standardization and the Coalition for Epidemic Preparedness Innovations organized a joint webinar on the use of platform technologies for vaccine development. To tackle new emerging infectious diseases, including SARS-CoV-2, rapid response platforms, using the same basic components as a backbone, yet adaptable for use against different pathogens by inserting new genetic or protein sequences, are essential. Furthermore, it is evident that development of platform technologies needs to continue, due to the emerging variants of SARS-CoV-2.
