The White House on Thursday confirmed it may require visitors from abroad to be vaccinated as part of its plans to eventually reopen international travel but said it had yet to decide and would not immediately lift restrictions. White House coronavirus response coordinator Jeff Zients confirmed that an interagency working group was developing plans that may require some type of vaccine requirement for foreign nationals. Reuters first reported the White House effort to develop vaccine requirements that could cover nearly all foreign visitors. "We will be ready when it is the right time to consider reopening," Zients said. The White House has said it is not ready to immediately lift restrictions because of the rising COVID-19 caseload and highly transmissible Delta variant. The extraordinary US travel restrictions were first imposed on China in January 2020 to address the spread of COVID-19. Numerous other countries have been added, most recently India in May.
