The rapid speed at which researchers are developing coronavirus vaccines doesn’t mean that safety is being sacrificed, said Anthony Fauci, the US government’s top infectious-disease expert.
“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, the head of the National Institute of Allergy and Infectious Diseases and one of the top US health officials, said on Wednesday.
Fauci has said numerous times he is cautiously optimistic that a vaccine for Covid-19 will be available at the end of this year or early 2021. He said in the interview that by working ahead to secure trial sites and manufacturing for the vaccine, it allows the process to move more quickly.
