Booster shots are ready for Georgians. Shortly after midnight Friday, Rochelle Walensky, director of the Centers for Disease Control and Prevention, ended a week of debate and votes and gave the final green light. Many—perhaps most—adults who got the Pfizer shots at least six months ago are now eligible.

Walgreens and CVS say as of Friday afternoon they are now giving booster shots to those eligible. They advise people to make appointments first. The Georgia Department of Public Health will start giving the shots Monday. Hospitals and clinics are gearing up, too.

The federal Centers for Medicare and Medicaid Services announced Friday that approved booster shots would be free, just like the original vaccines.

“I think it’s great news,” said Dr. Melissa Black, who treats homebound and elderly patients in metro Atlanta. “The vast majority of my patients are already vaccinated and I have been getting requests for two weeks.”

The CDC’s final order capped off a week of heated arguments over what groups should get the booster shot—or if anyone should get it, considering that the far graver problem is people who aren’t vaccinated at all.
