Kids should be able to go trick-or-treating this Halloween with a couple of caveats, Rochelle Walensky, director of the Centers for Disease Control and Prevention, said on Sunday.

Walensky, CBS’ Face the Nation’s director of the Centers for Disease Control and Prevention said that “I definitely hope so” as she was asked if it is safe to trick-or-treat this year. “If you’re able to be outdoors, absolutely,” she said.

The head of CDC suggested that children and parents “limit” Halloween crowds.

Walensky explained that although I would not necessarily attend a packed Halloween party, Walensky believed it was possible for children to go trick-or treating in small groups. I hope we can achieve that this year.

On Monday, Pfizer and BioNTech announced a smaller dose of their Covid-19 vaccine is safe and generates a “robust” immune response in a clinical trial of kids ages 5 to 11.

Pfizer The CEO and chairman Albert Bourla stated that the data will be submitted to FDA soon.

“It’s a question of days, not weeks,” Bourla said in an interview on ABC’s “This Week.”

“Then it is up to FDA to be able to review the data, and come to their conclusions, and approve it or not,” Bourla said. We will have the manufacturing capabilities to produce this vaccine if they approve.

For children aged five to 11, the vaccine is only one-third as effective as the other dose.

Walensky, a CDC spokesperson, said that coronavirus is not transmitted to children while they’re at school, even though schools have been back in session for the most part.

Walensky stated that science shows the illness is usually transmitted from the community. If schools have proper prevention and mitigation strategies, this isn’t where the disease is really spreading.

The CDC chief stated that schools should take safety precautions to prevent transmission.

Walensky stated that 96% of schools have been open throughout the school year.

Walensky added that an Arizona study showed that schools without masks are three-and-a-half times more likely than areas with masks.

Walensky stated that “We have the knowledge to protect them.” Walensky stated, “And when they don’t utilize the correct mitigation strategies, they are more likely to get outbreaks and need to close.”
