The United States is the only Western nation still mandating international visitors be vaccinated against Covid-19.

The House debated, and later passed, a bill to terminate the requirement imposed by the director of the Centers for Disease Control and Prevention for proof of COVID-19 vaccination for foreign travelers.

I assume this now goes the President for approval & signature or veto………..?
