The president on Monday held a press conference to praise the FDA's ultimate approval of the Pfizer vaccine.
But even as he delivered good news, he angered some with his advice.
'So let me say this to parents. You have the tools. You have the tools to keep your child safer. And two of those tools above all are available to you,' he stated. 'One: make sure everyone around your child who can be vaccinated is vaccinated. Parents, adults, teens.
'Two: make sure your child is masked when they leave home. That's how we can best keep our kids safe.'
Dr. Muge Cevik, a virologist from the University of St Andrews in Scotland, told the New York Times in May that the probability of getting COVID from an infected person outdoors is below one percent, and could even be as low as 0.1 percent.
And recent statistics from the American Academy of Pediatrics (AAP) showed that between 0.2 percent and 1.9 percent of COVID cases in children registered across all 50 states ended in hospitalization.
Notwithstanding those numbers, Biden explained that he was aware that 'parents are concerned about COVID-19 cases among their children', and said that he and Education Secretary, Miguel Cardona, are discussing 'how to get our kids back to school safely.'
He went on: 'Cases among children are still rare. And severe cases among children are very, very rare.
'I know that for parents thinking about their own kids, it's not as reassuring as anyone would like it to be.'
Big companies like Amtrak, Walt Disney and Walmart have already asked their workers to be immunized and the Pentagon have announced they will mandate all troops.
Though Biden's calls for all companies to make their demands stricter is likely to face calls of federal government overreach and legal challenges.
States including Florida and Texas have already fought back against vaccine mandates, stating people should not be forced to get the shots. Biden, speaking at the White House, portrayed Monday's official approval as a huge victory, even though it will be of limited practical value months after the vaccination got emergency approval.
