Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said that the rapid speed at which researchers are developing COVID-19 vaccines does not mean that safety is being sacrificed, Bloomberg reported on Wednesday.
"The rapidity with which we are moving relates more to technological advances with how you can make a vaccine even before you start testing it," Fauci said, adding that working ahead to secure trial sites and manufacturing for the vaccine allows the process to move more quickly.
He said that he hopes a vaccine is at least 70% effective but if it is more like 50% to 60% effective, adding that "I'll feel good about that."
Fauci further noted that the US needs to improve on efforts to test for the coronavirus.
"We need to do better," Fauci said, adding that results should come back in 24 to 48 hours, otherwise longer wait times obviate the reason for the test.
