Researchers around the world are developing more than 165 vaccines against the coronavirus, and 27 vaccines are in human trials. Vaccines typically require years of research and testing before reaching the clinic, but scientists are racing to produce a safe and effective vaccine by next year.
Work began in January with the deciphering of the SARS-CoV-2 genome. The first vaccine safety trials in humans started in March, but the road ahead remains uncertain. Some trials will fail, and others may end without a clear result. But a few may succeed in stimulating the immune system to produce effective antibodies against the virus.
Here, The NEW York Times, is the status of all the vaccines that have reached trials in humans, along with a selection of promising vaccines still being tested in cells or animals.
