Third COVID vaccine shot for people with weakened immune system 'very high priority,' Fauci says

Federal health officials are working "as quickly as possible" to authorize a third Covid-19 vaccine shot for Americans with weakened immune systems, White House chief medical advisor Dr. Anthony Fauci said Thursday.

It is clear now that such people – including cancer and HIV patients or those who have had organ transplants – in general do not produce an adequate immune response after receiving two doses of a Covid vaccine, Fauci said.
