As of November 8, 2021, foreign nationals flying to the United States must be fully vaccinated and provide proof of vaccination before boarding US-bound flights. This mandate, which came into effect following the COVID-19 pandemic, requires airlines to ensure that all foreign passengers aged two and above, regardless of nationality or vaccination status, present documentation of a negative viral test result within a specified time frame before departure. However, it's important to note that the US Supreme Court's decision to overturn the vaccine mandate suggests that US domestic carriers may not legally require vaccinations for their crews or passengers traveling within the country.

Foreign nationals must be fully vaccinated
As of November 8, 2021, foreign nationals flying to the United States must be fully vaccinated and must show proof of vaccination before boarding a US-bound flight. This mandate is part of the new international air travel policy, which includes other COVID-19 mitigation strategies such as enhanced testing, contact tracing, and masking. The policy was implemented to advance the safe resumption of international air travel to the United States and move away from country-by-country restrictions.
It is important to note that children under 18 are exempt from the vaccination requirement for foreign national travelers due to the ineligibility of younger children for vaccination and the global variability in access to vaccination for older children. However, they need to present a negative test result taken within three days of traveling. Additionally, non-tourist visitors from countries with low nationwide vaccination rates are also exempt from the mandatory vaccination status.
The CDC has determined that accepted vaccines include those approved or authorized by the FDA or those with an emergency use listing (EUL) from the World Health Organization (WHO). This includes vaccines such as Pfizer, Moderna, Johnson & Johnson, AstraZeneca, and China's Sinopharm and Sinovac. These vaccines must be received at least two weeks prior to travel.
While the US has mandated vaccination for foreign nationals, it is important to note that the country has not implemented a vaccine mandate for its domestic carriers. Following the US Supreme Court's decision to overturn the vaccine mandate, US domestic carriers are not legally required to mandate vaccinations for their crew and passengers flying within the country. However, individual airlines may still choose to encourage or recommend vaccinations for their staff and customers.

Exemptions for US citizens and permanent residents
As of 26 October 2021, full vaccination status is mandatory for almost all visitors arriving in the US. However, there are some exemptions for US citizens and lawful permanent residents (LPRs).
US citizens and LPRs who are unvaccinated will still be permitted entry, provided they can present a negative test result taken within 24 hours of departure. Children under 18 are also exempt from vaccination requirements, but they need to show a negative test result taken within three days of travelling.
In addition to the above exemptions, the US has a Visa Waiver Program (VWP) that allows citizens of 42 countries to enter the US for business or tourism for up to 90 days without a visa. This program is administered by the Department of Homeland Security (DHS) in consultation with the State Department. To be eligible for the VWP, travellers must have a passport or US-issued photo identification that meets the DHS's REAL ID requirements.
It is important to note that US authorities have broad powers to decide who can enter the country and may deny entry for any reason under US law. They actively pursue, detain, and deport individuals who are in the country illegally or who violate the terms of their entry or status. Participating in protests or demonstrations, including online, may be considered a violation of status and grounds for deportation or denial of a visa and/or immigration requests.

Negative test results required for unvaccinated
As of November 8, 2021, the US requires all foreign nationals flying to the country to be fully vaccinated and to show proof of vaccination before boarding. Children under 18 are exempt from this mandate, as are US citizens and lawful permanent residents (LPRs) who are unvaccinated but can provide a negative test result taken within 24 hours of departure. The CDC recommends that unvaccinated children under 2 years old should also be tested before departure, if possible.
The US has implemented these measures as part of its new international air travel policy, which aims to mitigate the risks of COVID-19 through enhanced testing, contact tracing, and masking. The policy applies to all travellers, regardless of nationality or vaccination status, and requires a negative viral test result within one day of the flight's departure. This test result must be shown to the airline before boarding.
For unvaccinated US citizens and LPRs, it is essential to adhere to the testing requirement. A negative test must be taken within the specified timeframe of 24 hours before departure. Failure to provide valid test results may result in denied boarding, as the airline is responsible for ensuring all passengers comply with the requirements.
It is worth noting that the US Supreme Court's decision to overturn the vaccine mandate suggests that domestic carriers may not legally require vaccinations. However, individual airlines have the autonomy to implement their own policies, and many are leaning towards encouraging or requiring their crews to be vaccinated. Therefore, while vaccination may not be mandatory for passengers flying within the US, specific airlines or routes could have their own rules and recommendations in place.
To summarise, while vaccination is not mandatory for domestic travel within the US, unvaccinated individuals may need to provide negative test results within specific time frames, depending on their age and residency status. It is always advisable to stay informed about the latest guidelines and requirements before planning travel, as policies may evolve in response to public health needs.

Vaccination requirements for cabin crew
As of November 2021, the US requires all visitors arriving in the country by air to provide proof of full vaccination status from an "official source" and present a negative test result taken within 72 hours of departure. Only vaccines approved by the Federal Drug Administration (FDA) or World Health Organization (WHO) are accepted, including Pfizer, Moderna, Johnson & Johnson, AstraZeneca, and China's Sinopharm and Sinovac jabs. US citizens and lawful permanent residents who are unvaccinated will still be permitted entry with a negative test result within 24 hours of departure. Children under 18 are also exempt from vaccination requirements but must present a negative test result within three days of traveling.
While there are no specific mandates regarding vaccination requirements for cabin crew in the US, individual airlines may have their own policies. Generally, airlines require cabin crew members to be in good health and undergo a series of medical examinations to detect any possible diseases or illnesses that could aggravate during flights. Additionally, as of December 2022, countries like China, Indonesia, Nepal, Myanmar, Taiwan, the USA, Singapore, Seychelles, Sri Lanka, Zimbabwe, and Hong Kong require proof of full COVID-19 vaccination for entry. Therefore, cabin crew members flying to these destinations may be required by their airlines to show proof of vaccination.
Some airlines, such as Emirates, Etihad, and Qatar Airways, have been specifically mentioned in relation to COVID-19 vaccination requirements for their cabin crew. While Dubai, UAE, has lifted all COVID-19 health requirements, destinations served by these airlines still require proof of COVID-19 vaccination. Thus, cabin crew members working for these airlines may need to be fully vaccinated.
It is important to note that the landscape of COVID-19 vaccination requirements is constantly evolving, and policies can change over time. Therefore, it is advisable to check with specific airlines regarding their most up-to-date vaccination requirements for cabin crew members.
In addition to vaccination considerations, there are other standard requirements for individuals aspiring to become cabin crew members. These include age requirements, with most European airlines mandating a minimum age of 18 years, while some Middle Eastern airlines require a minimum age of 21 years. Height restrictions are also in place, varying between airlines, and swimming proficiency is mandatory for health and safety reasons. Excellent English language skills, both written and spoken, are often essential, and physical fitness is a prerequisite to meet regulatory and role requirements.

Yellow Fever vaccine for travel to Africa and South America
As of November 2021, full vaccination status is mandatory for almost all visitors arriving in the US, with some exceptions. These include US citizens and lawful permanent residents who are unvaccinated but can provide a negative test result taken within 24 hours of departure. Children under 18 are exempt from vaccination requirements but must present a negative test result taken within three days of travelling. Non-tourist visitors from countries with low nationwide vaccination rates are also exempt from mandatory vaccination status.
Yellow Fever is a virus spread by mosquitoes that is found in parts of Africa and South America. It is transmitted to humans through the bite of infected mosquitoes. The Haemagogus mosquito, commonly found in Central and South America, has caused several yellow fever epidemics in those regions. The Aedes mosquito, found worldwide, carries most mosquito-borne infections, including yellow fever. The Yellow Fever vaccine is recommended for people aged 9 months or older who are travelling to or living in areas at risk for the yellow fever virus in Africa and South America. The vaccine is a live, weakened form of the virus, and a single dose provides life-long protection for most people. An International Certificate of Vaccination or Prophylaxis (ICVP) is often required for entry into countries where yellow fever is present. Certain countries may require proof of vaccination for entry, or proof of arrival from a non-affected country.
Some individuals may have an increased risk of developing a reaction to the vaccine and should consult a healthcare provider before travelling. These include people who are under nine months or over 60 years of age, and those with weak immune systems. Reactions to the vaccine are generally mild and include headaches, muscle aches, and low-grade fevers. However, in rare cases, people may develop severe, sometimes life-threatening reactions, including allergic reactions, swelling of the brain or spinal cord, and Guillain-Barré syndrome.
YF vaccination is generally not recommended for travel to areas where the potential for YF virus exposure is low. Vaccination may be considered for travellers going to these areas who are at increased risk of exposure due to prolonged travel, heavy exposure to mosquitoes, or inability to avoid mosquito bites. It is important to consider destination-specific risks and individual risk factors when deciding whether to vaccinate. Since 2016, the YF vaccine booster requirement has been eliminated, and an ICVP is considered valid for the life of the vaccinated person.
