On 6/10/20, The New York Times published a “coronavirus vaccine tracker,” by Jonathan Corum and Carl Zimmer. With prose and graphics, it describes the status of SARS-CoV-2 vaccine candidates currently being developed and tested. The piece explains the timeline of the phases involved in developing a vaccine (or other therapy), i.e. the path from preclinical testing (animal research) to phase 3 efficacy trials (experiments testing the effectiveness of a vaccine or therapy in thousands of people) and approval. The names of companies developing vaccine candidates and each company's progress through the phases are listed for each type of vaccine approach, e.g. genetic vaccines, viral vector vaccines, etc. The counts reported in the story: 125 or more vaccine candidates in preclinical experiments; 7 in phase 1 (small safety studies in humans), 7 in phase 2 (safety tests on hundreds of people), 1 in phase 3, and 0 approved by regulators in each country.
