The United States must stick to a two-dose strategy for the Pfizer-BioNTech and Moderna Covid-19 vaccines, top US infectious disease official Anthony Fauci told the Washington Post newsppaer.
Fauci said that delaying a second dose to inoculate more Americans creates risks, the newspaper reported on Monday.
He warned that shifting to a single-dose strategy for the vaccines could leave people less protected, enable variants to spread and possibly boost skepticism among Americans already hesitant to get the shots.
