Children will still be required to wear face masks at school for the remainder of the school year, regardless of vaccinations, the director of the Centers for Disease Control and Prevention asserted Tuesday — despite the country recording its lowest number of new daily COVID-19 infections since last summer.

CDC chief Rochelle Walensky doubled down on the current guidance for students at a White House coronavirus briefing — and stopped short of saying whether the public health agency would lift the mask mandate for the new school year.

The guidelines for schools — which recommend face coverings be worn at all times, except when eating or drinking — go against the CDC’s announcement last week that fully vaccinated Americans can go mask-free indoors in most circumstances.

“We are now working diligently to work through all of our active guidance in the context of this new science related to fully vaccinated,” as it pertains to the fall, Walensky said.

Walensky’s hesitation came after she hailed the US on a “landmark day” Monday — noting that more than 4 million children, ranging from 12- to 17-years-old, have been inoculated and that 60 percent of Americans aged over 18 have received at least one jab.

In less than a week since the FDA authorized and CDC recommended use of the Pfizer vaccine for adolescents, more than 600,000 kids aged 12- to 15-years-old have been vaccinated, the CDC chief noted.

“We have truly made tremendous strides across the country to ensure people have access to vaccines,” she said.

Still, many children “will likely not have the opportunity to be fully vaccinated before the end of the school year,” Walensky said when defending the CDC’s guidance for schools.

Meanwhile, the US has also reached milestones when it comes to new cases and deaths.

The number of new coronavirus infections reported on Monday hit the lowest daily tally since last June — with 17,724 new cases recorded nationwide, according to CDC figures.

Similarly, the seven-day deaths average dropped to 536 fatalities per day — the lowest recorded by the agency since last March.​​

Andy Slavitt​, a senior adviser to the White House Coronavirus Taskforce, urged young Americans to get vaccinated — saying that his son, who tested positive for COVID last fall, is still experiencing shortness of breath and flu-like symptoms.​

“Get vaccinated. Whether you’re a graduate, still in high school and college, just our or more than a little bit out, it’s the most important thing you can do right now,” ​Slavitt said during the briefing.

“Young people have been through a lot in this pandemic. In many ways, the pandemic has been as hard on young people as anyone,” he continued.

“The pandemic disrupted your schooling, your job search, your income, your social lives. Some of you lost parents, grandparents, or other loved ones.​ ​You’ve seen ​and experienced stress, in a way you probably haven’t before.  

“I know it’s been an anxious time, and you’ve been asked to do difficult things, but there is light at the end of the tunnel.”
