Omicron, the newest COVID-19 variant dubbed a “variant of concern” by the World Well being Group, has prompted new journey restrictions in many countries. Though little is understood about omicron, scientists have expressed concern that it might be extra transmissible or vaccine-resistant than earlier variants.
On Nov. 26, 2021, the US joined a rising checklist of countries banning vacationers from international locations in southern Africa, the place the variant was first recognized. The U.S. resolution adopted one other current change, which went into impact on Nov. 8, 2021, requiring non-citizens getting into the U.S. by airplane to be totally vaccinated, with restricted exceptions. Everybody getting into by airplane, together with residents, should present a adverse COVID-19 take a look at.
As bioethicists primarily based within the U.S. and Ghana, we discover the intersection of world well being and ethics in our analysis. Within the U.S. authorities’s current guidelines for entry, we see far-reaching penalties that ought to immediate policymakers to think about not simply science, however ethics.
Shopping for time?
There are a number of arguments to assist journey guidelines imposing bans or requiring full vaccination. U.S. coverage goals to “stop additional introduction, transmission, and unfold of COVID-19 into and all through the US,” President Joe Biden mentioned as he launched the vaccination requirement. He famous that the Facilities for Illness Management and Prevention “has decided that the easiest way to sluggish the unfold of COVID-19, together with stopping an infection by the delta variant, is for people to get vaccinated.”
Ethically, the rationale to comprise the unfold is to guard well being and save lives. It might be argued {that a} nation’s first obligation is to maintain its personal individuals protected. Nonetheless, many international locations handle to guard their individuals whereas constructing in flexibility, reminiscent of by testing and quarantining guests in lieu of journey bans or strict vaccination necessities. France, for instance, tailors necessities to an infection charges. It considers the U.S. an “orange” nation, which means unvaccinated Individuals should present adverse COVID-19 checks and self-isolate for seven days.
One argument in favor of journey bans holds that they may sluggish the unfold of the virus and purchase time whereas scientists study extra. Anthony Fauci, the U.S. authorities’s high infectious illness advisor, reportedly advised the president it might take two weeks to have definitive solutions about omicron. A journey ban offers scientists extra time to evaluate how nicely present vaccines fare in opposition to new variants, and to start reformulating vaccines if wanted.
An moral argument for vaccine necessities is that folks must be held accountable for his or her selections, together with refusing vaccination. But all through a lot of the world, significantly poorer areas, individuals can’t entry vaccines. On common, solely 6% of individuals in low-income international locations have obtained a dose of a COVID-19 vaccine, in comparison with 74% in wealthy international locations.
Science in flux
Critics of journey bans and vaccine necessities level out that such controls are hardly foolproof. There may be scant proof that journey restrictions cut back illness unfold, significantly if they don’t seem to be timed proper and paired with different prevention methods. In the meantime, many research have highlighted the adverse penalties of worldwide journey restrictions, reminiscent of xenophobia and psychological well being issues.
Vaccines are at the moment extremely efficient at stopping hospitalization and demise from COVID-19. However vaccinated individuals can nonetheless be contaminated and transmit the virus, though they’re much less seemingly than unvaccinated individuals to be contagious, and fewer prone to get COVID-19 within the first place. Vaccines may additionally grow to be much less efficient if undercut by new virus variants, although it’s not but clear if omicron reduces vaccine efficacy. Lastly, there may be uncertainty about how lengthy vaccine safety lasts.
Banning vacationers in response to omicron is meant to maintain individuals protected. However bans may backfire if they’re seen as punitive, and will make international locations much less prone to share details about new variants. After South Africa reported the omicron variant, its well being minister mentioned journey bans had made the nation a scapegoat for a “worldwide downside,” whereas the overseas ministry claimed, “Wonderful science must be applauded and never punished.” Focusing on African international locations with journey bans “assaults world solidarity,” the World Well being Group’s Africa director mentioned in an announcement.

Well being and justice
Journey bans and vaccine guidelines additionally increase fairness issues, given the dramatic disparity in vaccination charges throughout the globe. Journey restrictions disproportionately affect individuals from low-income nations the place few vaccines can be found.
It would seem that requiring vaccination for entry wouldn’t go away many individuals worse off, if individuals in poorer international locations can not often afford journey. But many individuals touring to wealthier international locations achieve this for jobs. Pre-pandemic, in 2019, the U.S. issued greater than 900,000 work-eligible visas.
Many opponents of journey restrictions emphasize that new variants are usually not stunning, given how unequally vaccines have been distributed across the globe. When nations in southern Africa protested the brand new journey ban, they pointed to earlier warnings that the delay in rolling out vaccinations there would enhance the chance of latest variants.
Fairness issues are intensified by rich nations’ partial duty for poorer nations’ problem accessing vaccines. Early within the pandemic, wealthy international locations struck advance market agreements and secured as a lot as 500% of their predicted vaccine want, exacerbating world vaccine shortage and bidding up costs.
Rich nations pledged 1.8 billion doses of vaccine to low-income nations by way of COVAX, a worldwide initiative to equitably distribute vaccines. But solely 14% of them have been delivered, in keeping with The Folks’s Vaccine, an alliance calling for equal entry to COVID-19 vaccines.

Some ethicists have argued that governments ought to maintain off on vaccination necessities for worldwide vacationers till there may be extra common entry to vaccines, or permit options, reminiscent of testing or vaccination upon arrival. The U.S. vaccine requirement for guests does make humanitarian exceptions for vacationers from international locations the place fewer than 10% of persons are totally vaccinated. Nonetheless, it bars entry to individuals on a vacationer or enterprise visa, and residents of many low- and middle-income nations the place vaccination charges are low, however simply above the bar.
Do as I say, not as I do?
The U.S. vaccination requirement additionally sounds hypocritical, as a result of it doesn’t apply to Individuals. Unvaccinated residents are allowed to reenter the nation with a adverse take a look at end result. Although free COVID-19 vaccines are broadly out there, simply 58% of the U.S. inhabitants is totally vaccinated.
As well as, U.S. guidelines exclude unvaccinated foreigners from international locations with far decrease COVID-19 charges. The U.S. has about 210 confirmed instances per million individuals, however excludes unvaccinated individuals from international locations together with India (6 per million), Paraguay (8 per million), Cambodia (2 per million) and Zimbabwe (3 per million), though lack of testing could contribute to low case counts.
In our analysis, we argue world well being may be protected by extra equitable strategies, like following the WHO’s advice to delay booster pictures till 10% of individuals in each nation have obtained first pictures; increasing vaccine manufacturing by way of waiving vaccine patents; and exhibiting solidarity within the world distribution of vaccines by prioritizing international locations with low skill to acquire vaccines.
In the end, the easiest way for rich nations to guard their very own residents is to vaccinate individuals throughout the globe. “If the variant reveals up wherever on the earth, you’ll be able to just about rely on it being all over the place on the earth,” as infectious illness specialist Michael Osterholm advised the New York Occasions. Vaccinating extra individuals reduces the possibility of latest variants showing which are impervious to vaccines.
