The Brooking Institution looks at vaccine passports and why a U.S. privacy law is needed to properly protect health information.

"As Congress continues to debate the need for federal privacy legislation, now is the time to implement a national standard on how personal data is collected and processed to avoid the abuse of fundamental rights," Brookings' Nicol Turner Lee, Samantha Lai and Emily Skahill write.
