(CNN) — The US Centers for Disease Control and Prevention says in newly updated guidance for summer camps that people who can get vaccinated against Covid-19 should do so, but everyone should wear masks, distance is still necessary and staying outdoors is best.

In guidance posted on Saturday, the CDC notes that vaccines are not yet authorized for children of all ages, so prevention measures such as mask-wearing and physical distancing must continue, even after camp employees are vaccinated. With few exceptions, “all people in camp facilities should wear masks at all times,” it says. Masks should not be worn while eating, drinking or swimming, the guidance notes.
