It's been well over a year since many people in the U.S. began working from home due to the coronavirus pandemic.

Many state and city officials welcomed news from the Centers for Disease Control and Prevention on Thursday that fully vaccinated people in the U.S. can forgo masks and social distancing.

But some still stopped short of immediately implementing the changes.

The CDC said vaccinated people must follow existing state, local or tribal laws and regulations on masks and social distancing, as well as policies at businesses and workplaces.

When the CDC announced on Thursday that fully vaccinated people can safely take off their masks in most settings, one group that did not necessarily breathe a sigh of relief was the parents of young children.

Some noted that the CDC's new guidance does not have any specific advice for vaccinated parents with unvaccinated kids in their households.

Ben Tobin has questions about the Grand Canyon’s caves.

The University of Kentucky geologist started learning about caves as a young man, in part because his mother was a geologist, and a childhood fascination grew over time.

“Caves are a really special place in many ways,” Tobin said.

When he was in college, an internship in Arkansas doing cave tours got him hooked, and eventually his work brought him out West, to Grand Canyon National Park.

Last year, the Irish people raised nearly $2 million dollars for the Navajo and Hopi Nations so they could protect themselves from the pandemic. At the time, the infection rate in the Navajo community – 2,304 cases per 100,000 — was the highest in the country and nearly 40% higher than even the epicenter of New York City.
