COVID-19 boosters can be mixed, original vaccine recommended - Fauci

Americans can choose a COVID-19 booster shot that is different from their original inoculation but the recommendation is to stick with the vaccine they got first if it is available, White House chief medical adviser Dr. Anthony Fauci said on Friday.

"It's generally recommended that you get the booster that is the original regimen that you got in the first place," Fauci, director of the National Institute of Allergy and Infectious Diseases, said in an interview with CNN.

"But for one reason or other - and there may be different circumstances with people, availability or just different personal choices - you can, as we say, mix and match," Fauci concluded.
