Between Nov 3 and 4, an estimated 112 children ages 5 to 11 were incorrectly administered a COVID-19 vaccine dose intended for people ages 12 and older at Ted Pharmacy in Aldie of Virginia, said the Virginia Department of Health in a statement on earlier this week.

"Our understanding is that Ted Pharmacy attempted to give the correct 10 microgram dosage to those under 12 by administering 0.1 ml of the adult formulation," said David Goodfriend, director of the Loudoun County Health Department. "Due to the very small volume used, and concerns raised by some parents as to whether 0.1 ml was actually administered, it is possible some children were under-dosed."

The Lincoln Children's Zoo in Nebraska announced Friday evening that three of its snow leopards had died of complications from COVID-19, adding that two Sumatran tigers who contracted the virus at the zoo had "seemingly" recovered.

"Our leopards, Ranney, Everest, and Makaly, were beloved by our entire community inside and outside of the zoo," the zoo said in a statement. "This loss is truly heartbreaking, and we are all grieving together." The zoo first reported that the tigers and snow leopards tested positive for COVID-19 on Oct 13.
