Introducing the new recommendations on Thursday, Dr. Rochelle P. Walensky, the C.D.C. director, cited two recent scientific findings as significant factors: Few vaccinated people become infected with the virus, and transmission seems rarer still; and the vaccines appear to be effective against all known variants of the coronavirus.
One of the lingering concerns among scientists had been that even a vaccinated person might carry the virus perhaps briefly, without symptoms and spread it to others. But C.D.C. research, including the new study, has consistently found few infections among those who received the Pfizer-BioNTech and Moderna vaccines.

The German company CureVac hopes its RNA vaccine will rival those made by Moderna and Pfizer-BioNTech. It could be ready next month. In early 2020, dozens of scientific teams scrambled to make a vaccine for Covid-19. Some chose tried-and-true techniques, such as making vaccines from killed viruses. But a handful of companies bet on a riskier method, one that had never produced a licensed vaccine: deploying a genetic molecule called RNA.
