US will create new strain of coronavirus for vaccine development

The U.S. government is engineering a new strain of the coronavirus that it may use in human volunteers to develop a COVID-19 vaccine, The Washington Post reported.

Health officials said they doubt they will need to resort to "human challenge" experiments and Anthony Fauci, MD, head of the National Institute of Allergy and Infectious Diseases, said it would be "plan C or plan D" in vaccine development.
