There are seven coronavirus vaccine candidates being tested in the U.S. heres where they stand – MarketWatch

The race to develop a safe and effective COVID-19 vaccine is well under way, setting the stage to bring to market the fastest vaccine in history.

There are dozens of coronavirus vaccines in development, primarily in the preclinical phase when they are tested on animals. In the U.S., there are seven vaccine candidates that have moved into clinical trials with human participants, including three that have moved into the crucial Phase 3 development phase.

The first and second phases of clinical studies are primarily conducted to test for safety, while the third and final stage is used to determine whether vaccines are efficacious and can prevent infection among participants. At that point, the vaccine makers will decide when to pursue an emergency-use authorization from the Food and Drug Administration and/or a full approval. The majority of the vaccines in development have received funding from the U.S. government, either to help support clinical development or pay for manufacturing and distribution of the vaccines as part of the Trump administrations Operation Warp Speed program.

MarketWatch will update this tally as the vaccines move through development.
