Dr. Leana Wen explains the latest risks Omicron poses to families and children

As the Omicron variant surges across the country, people want to know the risk to someone who is vaccinated and boosted. And are vaccinated children safe to go back to school? What's the best way to protect kids under age five, who are too young to be vaccinated? Dr. Lena Wen tackles these questions.

To begin with, what is the risk of Omicron to someone who is vaccinated and boosted? Are vaccinated children safe to go back to school? Is it safe to continue going to restaurants and concerts? And what's the best way to protect kids under age 5 who are too young to be vaccinated?

For guidance, I spoke with our expert, CNN Medical Analyst Dr. Leana Wen, who is an emergency physician and professor of health policy and management at the George Washington University Milken Institute School of Public Health. She is also author of "Lifelines: A Doctor's Journey in the Fight for Public Health," and the mom of two young kids.
