The vaccine will likely require two doses at varying intervals, and states still face logistical challenges such as setting up distribution sites and acquiring enough needles, syringes and bottles needed for immunizations.
He said he "firmly" believes a vaccine will be available before the end of the year and "in quantities that can immunize patients at the highest risk, which means very old people, 70 years and older, and maybe people that are highly exposed on the first line." On Tuesday, the National Academies of Sciences, Engineering, and Medicine released a draft proposal for distributing a vaccine in the U.S. if and when one is approved for public use. The report was requested by the National Institutes of Health and the CDC.
