Coronavirus Vaccines

World-class vaccine scientists have accelerated the clinical trial process to develop a safe and effective coronavirus preventive vaccine. Currently, there are over 135 vaccine development projects underway.

Coronaviruses without preventive vaccines are the Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV), and the novel coronavirus SARS-CoV-2, which causes COVID-19 disease in humans.

The SARS-CoV-2 vaccine development landscape includes innovative platforms such as nucleic acid (DNA and RNA), virus-like particle, peptide, viral vector (replicating and non-replicating), recombinant protein, live attenuated virus and inactivated virus approaches.

The U.S. FDA has not approved any preventive or therapeutic vaccines for use against the SARS, MERS, or SARS-CoV-2 coronaviruses. However, over 300 clinical studies are seeking participants to evaluate coronavirus vaccine candidates.

Approved for Limited Use

  • Ad5-nCoV COVID-19 vaccine
    • On June 25, 2020, China's Central Military Commission approved the use of the vaccine by the military for a period of 1-year.
