No, “boosters” were only given to fully vaccinated people. “Boosters” are no longer available and have been replaced with updated vaccines that target dominant virus strains.

The best way to protect yourself from getting severely ill from COVID-19 is to get vaccinated. The CDC recommends that unvaccinated people age six months and older get the updated primary series, and then wait at least two months to get their second or third updated Pfizer-BioNTech or Moderna vaccine dose. 

Adults age 18 and older also have the option to receive an updated Novavax vaccine instead of an updated Pfizer-BioNTech or Moderna vaccine if they are unable to receive mRNA vaccines and haven’t previously received any other updated dose.
