Speaking during a COVID-19 response press briefing on Friday, Walensky was asked by an Associated Press reporter if the fully vaccinated status will one day be endangered for those who are protected but not boosted.
"Is the administration rethinking the definition of what it means to be fully vaccinated now that these boosters are recommended?" the reporter asked. "Should people who are eligible for a booster now get one by a certain time frame to maintain their fully vaccinated status?"
Walensky responded that it was a great question before further explaining.
"Right now, we don't have booster eligibility for all people," she said. "So, we are going to — we have not yet changed the definition of fully vaccinated. We will continue to look at shots. We may need to update our definition of fully vaccinated in the future. But right now, what I would say is, if you're eligible for a booster, go ahead and get your booster, and we will continue to follow."
The CDC has expanded its capability for boosters, enacting them for people who have received Pfizer-BioNTech or Moderna shots if they are 65 and older or 18 and older living in long-term care settings, with underlying medical conditions or working in high-risk settings.
Everyone 18 and older who has taken the Johnson & Johnson shot is fit for a booster after two months.
Earlier in the briefing, Walensky backed the 64 million people who are still unvaccinated to get their first shots. But she also recognized that even widespread boosters wouldn't mean an end to other coronavirus protocols.
"As you have heard me say before, we will not boost our way out of this pandemic, and no vaccine — even a boosted vaccine — provides 100% protection," Walensky said. "So even after you boost, it remains important for us to remain smart about our prevention strategies while we still have over 93% of our counties with high or moderate community transmission."
The White House said it had acquired enough vaccines to equip more than 25,000 pediatric and primary care offices, hundreds of school and community health clinics, and tens of thousands of pharmacies to administer the shots.
The White House added that the Department of Health and Human Services will "conduct a national public education campaign to reach parents and guardians with accurate and culturally responsive information about the vaccine and the risks that COVID-19 poses to children."
