Fauci says no guarantee US will have an effective Covid-19 vaccine

The United States cannot count on the availability of a safe and effective Covid-19 vaccine, the government’s top infectious diseases expert said on Tuesday, and he warned that the daily surge in cases could more than double if Americans fail to take steps to get the virus under control.

California, Texas and many other states have reported record increases in new cases of the sometimes deadly illness caused by the novel coronavirus, leading to a sobering reassessment of U.S. efforts to contain the pandemic. “It’s extremely important to have safe and effective vaccines available for everyone in this country,” Dr. Anthony Fauci, the head of the National Institute of Allergy and Infectious Diseases, told a U.S. Senate committee.

Scores of vaccine candidates using a variety of approaches are being developed and tested at unprecedented speed. Fauci, however, cautioned that “there is no guarantee … we’ll have a safe and effective vaccine,” and he urged Americans to come together to contain the virus.

Fauci warned that the daily increase of new cases in the United States, currently around 40,000, could reach 100,000 if people do not adhere to social distancing guidelines and wear masks. ‘I am very concerned because it could get very bad,’ he said.
