(Reuters) – The new regulations by the Biden administration requiring that most foreign nationals be vaccinated prior to flying to the United States go into effect at 12:00 a.m. EST (0501 GMT). Nov. 8.

These are the facts:

* Starting Nov. 8, foreign air travelers to the United States will be required to be fully vaccinated against COVID-19 and provide proof of vaccination status prior to boarding an airplane to fly to the United States, with limited exceptions.

* Passengers will need to show an “official source” showing vaccination status, and airlines will need to match the name and date of birth to confirm the passenger is the same person reflected on the proof of vaccination.

* The U.S. Centers for Disease Control and Prevention (CDC) has said it will accept U.S. Food and Drug Administration (FDA) approved or authorized and World Health Organization (WHO) emergency use listed vaccines.

* All travelers must produce a negative viral test result within three days prior to travel to the United States. All Americans who have not been vaccinated and all others exempted from vaccination must present a negative result within one calendar day of travel.

* Children under 18 are excepted from the vaccination requirement but children between the ages of 2 and 17 are required to take a pre-departure test. Unvaccinated foreign nationals under 18 will not https://www.reuters.com/world/us/cdc-clarifies-unvaccinated-young-foreign-travelers-do-not-need-quarantine-2021-10-30 have to self-quarantine upon arrival.

* If traveling with a fully vaccinated adult, an unvaccinated child can test three days prior to departure, but if an unvaccinated child is traveling alone or with unvaccinated adults, they will have to test within one day before departure.

* Exemptions include certain COVID-19 vaccine clinical trial participants, those with valid medical reasons for not getting vaccinated and those who need to travel for emergency or humanitarian reasons, but they will need a U.S. government-issued letter affirming the urgent need to travel.

* The CDC said there are no exceptions https://www.cdc.gov/coronavirus/2019-ncov/travelers/proof-of-vaccination.html#faq-overview for the vaccine requirements “for religious reasons or other moral convictions.”

* Non-tourist travelers from nearly 50 countries https://covid.cdc.gov/covid-data-tracker/#global-vaccinations with nationwide vaccination rates of less than 10% will be exempt from the requirements but must agree within 60 days to get vaccinated under most conditions.

* Travelers (NYSE:) must sign an attestation https://www.cdc.gov/quarantine/pdf/vax-order-passenger-attestation-10-25-21-p.pdf that they have been vaccinated and are warned that “willfully providing false or misleading information may lead to criminal fines and imprisonment.”

* The Transportation Security Administration (TSA) plans https://www.cdc.gov/quarantine/cruise/pdf/Vax-Order-10-25-21-p.pdf to issue a security directive that provides the legal basis for airlines to check vaccine records.

* The CDC also issued a Contact Tracing Order https://www.cdc.gov/quarantine/pdf/CDC-Global-Contact-Tracing-Order-10-25-2021-p.pdf that requires all airlines flying into the United States to collect and keep on hand for 30 days and disclose to the CDC if needed contact information including phone numbers, email and U.S. addresses that will allow health officials to track infections. This collection requirement will be in effect from Nov. 8.

*The CDC released a travel assessment https://www.cdc.gov/coronavirus/2019-ncov/travelers/international-travel/travel-assessment/index.html tool on Monday for people planning international trips, including an extensive question and answer https://www.cdc.gov/coronavirus/2019-ncov/travelers/proof-of-vaccination.html#faq section for travelers.
