“ Today, I want to share with you some new science that is emerging about masks and what we know now that we didn’t know when the pandemic started. The science is clear: Everyone needs to be wearing a mask when they are in public or when they’re in their own home but with people who do not live in their household. This is especially true with our ongoing concern about new variants spreading in the United States. Masks offer two kinds of protection. When I wear a mask, it protects you and it protects me. But to get the most protection possible, we all have to wear them. ”
