The U.S. Centers for Disease Control and Prevention has dropped masking and physical distancing guidance for campers and staffers who are fully vaccinated against COVID-19.

"Staff and campers who are fully vaccinated do not need to wear masks at camp, except where required by federal, state, local, tribal, or territorial laws, rules and regulations, including local business and workplace guidance," the CDC said in an update to its website on Friday. "Although fully vaccinated persons do not need to wear masks, camps can be supportive of staff or campers who choose to continue to wear a mask."

In the guidance, the CDC encouraged everyone 12 years and older to get vaccinated for COVID-19, and underscored that the vaccines are safe and effective.

The agency said people who are fully vaccinated to not need to undergo routine Covid-19 testing, and do not need to be tested – even if they are exposed to someone with a known COVID-19 infection "unless they are experiencing COVID-19 symptoms."
