One year into the COVID-19 pandemic, Dr. Anthony Fauci told "Good Morning America" Thursday that the "answer to get us back to normality" is a blend of vaccinations and a "gradual" easing of restrictions.

That includes "a combination of a very, very aggressive implementation of the vaccine program -- which you are actually seeing in real time -- together with a continuation of public health measures and a gradual pulling back, as opposed to just turning a light switch on and off," he said.

"That has happened in the past -- at least a couple of times over the past year," Fauci said.

Fauci said the most important message for President Joe Biden to deliver in his prime-time address Thursday is that the nation has "come a very long way over this past year" and "there is light at the end of the tunnel."

Liana Fonseca looks away as she receives the Pfizer COVID-19 vaccine, March 9, 2021, in Miami. Thousands packed the mass vaccination site at Miami Dade College, many waiting three hours or more to get the vaccine. By mid morning the site had ran out of the one dose Johnson & Johnson vaccine an only the Pfizer vaccine was available.

Among the "lights" in the tunnel to look for? Fauci said the Centers for Disease Control and Prevention will be rolling out recommendations "imminently" for activities for vaccinated individuals.

Thursday marks one year since the World Health Organization declared COVID-19 a pandemic.

Looking back, Fauci said, "It was exactly one year ago this morning that I said, 'Things are gonna get much worse before they get better.' But I did not realize in my mind even anything close to more than half a million people having died in this country."

CDC Director Rochelle Walensky said in a statement Thursday, "After a year of this fight, we are tired, we are lonely, we are impatient. There have been too many missed family gatherings, too many lost milestones and opportunities, too many sacrifices. And still, through it all, there is determination; there are stories of giving and hope, of stamina and perseverance. We are better together, and together, we will endure.

"The vaccination of millions every day gives me hope," Walensky said. "Hope that we can beat this pandemic. And hope that we can get back to being with our family, friends, and community. And soon."
