COVID-19 vaccine clinical research uses clinical research to establish the characteristics of COVID-19 vaccines. These characteristics include efficacy , effectiveness , and safety. As of November 2022 [update] , 40 vaccines are authorized by at least one national regulatory authority for public use: [ 1 ] [ 2 ]
The Pfizer–BioNTech COVID-19 vaccine, sold under the brand name Comirnaty, [2] [33] is an mRNA-based COVID-19 vaccine developed by the German biotechnology company BioNTech. For its development, BioNTech collaborated with the American company Pfizer to carry out clinical trials , logistics, and manufacturing.

[143] On 21 December 2020, the CHMP recommended granting a conditional marketing authorization for the Pfizer-BioNTech COVID‑19 vaccine, Comirnaty (active ingredient tozinameran), developed by BioNTech and Pfizer.
The purpose of this study is to determine if the investigational COVID-19 vaccines are safe and can stimulate and broaden the immune response against the different COVID-19 variants that cause COVID-19 when given as a single booster injection in participants who have previously been vaccinated with a full course of an authorized COVID-19 vaccine.
The vaccine consists of a version of the receptor binding domain (RBD) of the SARS‑CoV‑2 spike protein, together with the adjuvants aluminium hydroxide gel and CpG 1018. [2] As the RBD protein is poorly immunogenic alone, adjuvantation is essential for a RBD-based vaccine immunogenicity. [ 9 ]
ZF2001, trade-named Zifivax or ZF-UZ-VAC-2001, is an adjuvanted protein subunit COVID-19 vaccine developed by Anhui Zhifei Longcom in collaboration with the Institute of Microbiology at the Chinese Academy of Sciences.
