International travelers arriving in the United States will no longer have to show proof of vaccination against COVID-19. The requirement was lifted as the U.S. government on Thursday formally ended its public health emergency in response to the pandemic. Last week, the World Health Organization declared COVID-19 is no longer a global health emergency. COVID-19 has killed more than 1.1 million people around the U.S., though that’s widely believed to be a significant undercount. Globally, there have been nearly 7 million officially reported deaths. The true death toll is unknown, but the U.N. estimates at least 20 million.
