Sen. Diane Feinstein introduced a bill Thursday that would require passengers on domestic flights to be vaccinated, test negative or be fully recovered from a previous COVID-19 illness. 

Feinstein said the bill would require the secretary of Health and Human Services, in consultation with the Federal Aviation Administration, to develop national vaccination standards and procedures related to COVID-19 and domestic air travel in order to prevent future outbreaks of the disease.

Her office said the bill would also require the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices to make recommendations for COVID-19 vaccine use in health care settings and among health care personnel in other settings.

The legislation builds on a current CDC requirement that all air passengers traveling to the United States from a foreign country must provide proof of a negative COVID-19 test result or documentation of recovery from COVID-19.

Last week, the Biden administration announced it will work with airlines to implement additional protocols to prevent the spread of COVID-19 on international flights.

“We know that air travel during the 2020 holiday season contributed to last winter’s devastating COVID-19 surge. We simply cannot allow that to happen again,” Feinstein said.
