President Joe Biden has canceled the COVID-19 vaccination requirement for most foreign visitors entering the United States and ended the vaccination requirements for federal employees and contractors. The decision takes effect at 12:01 AM Eastern Time on May 12, coinciding with the end of the public health emergency related to COVID. It is noteworthy that Biden's rules imposed in September 2021, which required vaccination for approximately 3.5 million federal employees and contractors or face termination or disciplinary actions, were not enforced for more than a year following a series of court rulings.
