'Our highest priority still, is getting the unvaccinated, and there should be no confusion about that,' Dr. Fauci told NBC News' Meet the Press host Chuck Todd.
'The highest priority is not getting boosters,' he stated. 'We think it's important to get boosters to people, but the overwhelming highest priority is to vaccinate the unvaccinated.'
The clarification came after Todd asked the country's top immunologist regarding the prioritization of boosters shots and whether it's a 'luxury'.
The Food and Drug Administration's advisory committee voted last week to recommend against the Pfizer booster shot for the general public. Soon after, though, it did approve the shot for elderly Americans and those with pre-existing conditions.
'I don't think a booster is a luxury,' Fauci told NBC.
He further explained in an interview Sunday morning on CNN's State of the Union that while he is old enough to get the booster – at 80-years-old – he has not yet gotten it.
'I am 80 and I'm an elderly person,' he told host Jake Tapper. 'I will certainly get a booster.'
'They did that in the proper, deliberative process and they came up with a recommendation, which I think is a good recommendation,' Fauci stated.
He explained that the populations for whom a booster shot is supported by the FDA are a 'good chuck'.
Other than those over 65, the FDA explained that the Pfizer booster is suggested for adults with underlying conditions and those 18 and older who are at a higher risk of exposure – like those in the healthcare industry.
'They're going to continue to look at this, literally, in real-time,' Fauci continued in his interview with CNN. 'More data will be coming in on both safety for younger individuals, efficacy.'
'So the story is not over yet. I think people need to understand that. This is not the end of the story.'
Biden discovered himself ahead of the science on this one, stating last month the administration would deliver on a booster shot to intensify the vaccine's efficiency.
'The plan is for every adult to get a booster shot eight months after you got your second shot,' Biden said on August 18. 'Just remember as a simple rule: Eight months after your second shot, get a booster shot.'
