Fauci, who has also been involved with White House’s “Operation Warp Speed" vaccine program, said it may take until well into 2021 for vaccines to reach the much of the general public.“I would hope that by the time we get well into the second half of 2021 that the companies will have delivered the hundreds of millions of doses they have promised," said Fauci.The reasons are many.
U.S. health regulators will have only a tiny sliver of the usual safety and efficacy data. The leading products require two doses, which will limit how many people early supplies can help.
