NASHVILLE, TN (WSMV) - Pfizer’s booster shot has the green light from the FDA, but there are still a few hurdles it must go through before people can get it.

Seniors – those age 65 and older – will be eligible for the extra dose as well as those at risk for severe illness. People with compromised immune systems and essential workers exposed to COVID-19 will also be able to receive a third single dose shot.

Later Thursday a CDC panel will decide who else can get the shot.

“As we learn more about the safety and effectiveness of COVID-19 vaccines, including the use of a booster dose, we will continue to evaluate the rapidly changing science and keep the public informed,” FDA Commissioner Janet Woodcock said in a statement.

If the CDC director signs off on guidelines on Thursday, people getting their second Pfizer dose more than six months ago could be getting a booster shot by the end of the week.

No decision yet has been made for people who got shots of Moderna or the single-dose Johnson & Johnson vaccine, which some health experts believe could cause confusion.

“This is not the situation where we want to be, where people are eligible or not based on what vaccine they got,” Dr. Ashish Jha, Brown University School of Public Health, said. “It could be helpful for the FDS and the CDC to come out with broader guidance across a range of vaccines.”

The FDA is considering an application from Moderna for boosters and Johnson and Johnson has said it is considering an application for boosters. At this point, people who got the Johnson & Johnson and Moderna vaccines will have to wait. is now with you on the go!
