The new restrictions will apply to both travellers for essential and non-essential reasons. “These updated travel requirements reflect the Biden-Harris Administration’s commitment to protecting public health while safely facilitating the cross-border trade and travel that is critical to our economy,” DHS Secretary Alejandro N. Mayorkas said. Upon entry to the US via land ports or ferry terminals, non-US individuals will need to not only verbally attest to their COVID-19 vaccination status, but also provide proof of a Centres for Disease Control and Prevention (CDC)-approved COVID-19 vaccination and present a valid Western Hemisphere Travel Initiative (WHTI) compliant document, such as a valid passport. COVID-19 testing will not be required for entry via a land port of entry or ferry terminal, however. These changes were first announced by DHS in October. The mandate also aligns with public health orders for incoming non-US international air travellers, who are also required to be fully vaccinated as well as show proof of a negative COVID-19 test result. At the time of writing, the World Health Organisation reported that there have been more than 67,000,000 confirmed COVID-19 cases in the US and 849,200 deaths. Introducing such proof-of-vaccination mandates follow in the footsteps of other nations, such as Australia, which has made its position around the need to show proof-of-vaccination upon entry into the country clear. Australia recently drew global attention following the saga involving the world’s number one men’s tennis player Novak Djokovic and his COVID-19 vaccination status.
