Pfizer's COVID-19 vaccine is now officially approved for use. Up until now, it had Emergency Use Authorization only. The FDA’s decision to fully sign off came this morning after reviewing hundreds of thousands of pages of data from tens of thousands of trial participants around the world.

Adam Reilly, in for Jim Braude on Greater Boston, was joined by Dr. Sandro Galea, dean of Boston University's School of Public Health, to discuss how the FDA’s COVID vaccine approval might change the game and whether local college campuses are ready for the influx of students as the Delta variant continues to spread.

Reilly noted that a Kaiser Family Foundation poll had found that three in 10 unvaccinated people would be more likely to get vaccinated following its full approval.

“It makes it clear that this has gone through the strictest level of scrutiny — it is a safe and effective vaccine, and everybody should get vaccinated,” Galea said about the FDA approval.

“Given that we are in a situation where we have 20, 30 percent of the country continuing to resist vaccination, it feels to me the more official we can be about it, the more formal we can be about it… I think that is important.”
