A COVID‑19 vaccine is a vaccine intended to provide acquired immunity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID‑19).
CoronaVac, also known as the Sinovac COVID-19 vaccine, is a whole inactivated virus COVID-19 vaccine developed by the Chinese company Sinovac Biotech. It was Phase III clinical trialled in Brazil, Chile, Indonesia, the Philippines, and Turkey and relies on traditional technology similar to other inactivated-virus COVID-19 vaccines, such as the Sinopharm BIBP vaccine, another Chinese vaccine, and Covaxin, an Indian vaccine. CoronaVac does not need to be frozen, and both the final product and the raw material for formulating CoronaVac can be transported refrigerated at 2–8 °C (36–46 °F), temperatures at which flu vaccines are kept.
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. The vaccine candidate is in Phase III trials with 29,000 participants in China, Ecuador, Malaysia, Pakistan, and Uzbekistan.
CoVLP was a COVID-19 vaccine developed by Medicago in Canada and GlaxoSmithKline (GSK). The product and Medicago, Inc. were owned by Mitsubishi who terminated the company and program in February 2023 due to high international market competition for COVID-19 vaccines.
EpiVacCorona is a peptide-based vaccine against COVID-19 developed by the Russian VECTOR Center of Virology. The lack of protective effectiveness of EpiVacCorona, which is still in use in Russia, has been reported in scientific literature and in the media. The vaccine consists of three chemically synthesized peptides that are conjugated to a large carrier protein. This protein is a fusion product of a viral nucleocapsid protein and a bacterial MBP protein. A phase III clinical trial to show whether or not the vaccine can protect people against COVID-19 was launched in November 2020 with more than three thousand participants. The conclusions and results of the trial have not been made public.
The CureVac COVID-19 vaccine was a COVID-19 vaccine candidate developed by CureVac N.V. and the Coalition for Epidemic Preparedness Innovations (CEPI). The vaccine showed inadequate results in its Phase III trials with only 47% efficacy. In October 2021 CureVac abandoned further development and production plans for CVnCoV and refocused efforts on a cooperation with GlaxoSmithKline.
CoviVac is an inactivated virus-based COVID-19 vaccine developed by the Chumakov Centre, which is an institute of the Russian Academy of Sciences. It was approved for use in Russia in February 2021, being the third COVID-19 vaccine to get approval in Russia. It obtained a permission for phase III clinical trial on 2 June 2021.
QazCovid-in, commercially known as QazVac, is a COVID-19 vaccine developed by the Research Institute for Biological Safety Problems in Kazakhstan. QazCoVac-P is a second COVID-19 vaccine developed by the Kazakh Biosafety Research Institute and in clinical trials.
Nanocovax is a Vietnamese COVID-19 vaccine candidate developed by Nanogen Pharmaceutical Biotechnology JSC. It is a subunit vaccine.
iNCOVACC is an intranasal COVID-19 vaccine candidate developed by Bharat Biotech, American company Precision Virologics and the Washington University School of Medicine in St Louis, Missouri, United States.
A viral vector vaccine is a vaccine that uses a viral vector to deliver genetic material (DNA) that can be transcribed by the recipient's host cells as mRNA coding for a desired protein, or antigen, to elicit an immune response. As of April 2021, six viral vector vaccines, four COVID-19 vaccines and two Ebola vaccines, have been authorized for use in humans.
DelNS1-2019-nCoV-RBD-OPT is a COVID-19 vaccine candidate developed by Beijing Wantai Biological, Xiamen University and the University of Hong Kong.
NDV-HXP-S is a COVID-19 vaccine candidate developed under the leadership of Peter Palese, Adolfo García-Sastre, and Florian Krammer at the Icahn School of Medicine at Mount Sinai.
Razi Cov Pars is a COVID-19 vaccine developed by the Iranian Razi Vaccine and Serum Research Institute.
FAKHRAVAC is a COVID-19 vaccine developed in Iran by the Organization of Defensive Innovation and Research, a subsidiary of Iran's Ministry of Defense. It is the third Iranian COVID-19 vaccine reaching clinical trials. It is currently in phase III. It has received emergency use authorization in Iran on 9 September 2021.
COVAX-19 is the result of a collaboration between Vaxine and CinnaGen, a private company with operations in the Middle East. COVAX-19 is a recombinant protein-based COVID-19 vaccine developed by South Australian-based biotech company Vaxine. It is under clinical trial in collaboration with the Iranian company CinnaGen.
Skycovione is a COVID-19 vaccine candidate developed by SK Bioscience and the Institute for Protein Design of the University of Washington, It is South Korea's first homegrown Covid-19 vaccine and utilizes GSK's AS03 adjuvant technology.
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, 40 vaccines are authorized by at least one national regulatory authority for public use:
