For those lucky enough to have received an approved coronavirus vaccine, some tourism-hungry countries have announced that their borders will be flung wide to the immunised traveller.
Here is a list made by the Independent which show the destinations welcoming vaccinated holidaymakers.
In December, Cyprus became the first European Union Member State to announce it was planning to abolish entry requirements like testing and quarantine for travellers who get vaccinated against Covid-19.
The government has now announced that British nationals who have been vaccinated can enter the country without needing to quarantine or present a negative Covid test from 1 May.
This archipelago and autonomous region of Portugal is launching a "green corridor" for arrivals who are fully vaccinated or have recovered from Covid-19.
Tourists who can prove vaccination or recovery will no longer have to provide a negative Covid test.
To be eligible, tourists must prove their status through one of two documents: proof of Covid-19 recovery in the last 90 days, validated by the respective country of origin, stating the name, date of birth, health number, type and date of the test and explicit mention of 'recovered'; or the official vaccination certificate, including the date of the two doses taken and respect for the immunisation period according to instructions for each vaccine.
Documentation in English must be submitted to the 'Madeirasafe.com' app prior to arrival.
Poland has lifted quarantine requirements for travellers who have received both doses of the Covid-19 vaccine.
Visitors travelling from abroad who can provide proof of both jabs will not be required to quarantine upon arrival.
Those who can show proof of a negative Covid-19 test, taken within 48 hours before crossing the Polish border, can also bypass the restrictions.
Estonia has become the latest nation to offer quarantine exemption for travellers who have recovered from Covid-19 or who have been vaccinated against the virus.
The Ministry of Foreign Affairs currently imposes 10 days of quarantine on arrivals from abroad, with exceptions made only for low-risk European countries – Bulgaria, Finland, Greece, Iceland and Norway.
The ministry says: "Starting from 1 February, the 10-day self-isolation and Covid-19 testing are not mandatory for individuals, including those arriving from the United Kingdom of Great Britain and Northern Ireland or a third country, who: (1) have suffered from Covid-19 and no more than six months have passed since they have been declared cured; (2) have undergone Covid-19 vaccination and no more than six months have passed since its completion."
According to the Foreign Office, proof of recovering from Covid-19 should be a doctor's certificate that includes the time, location, methodology and result of the analysis, as well as the details of "the institution that conducted the analysis".
Vaccinated travellers will need to provide "an immunisation passport", even though there is no international agreement on such a document, or a vaccination certificate with a similar level of detail to the doctor's certificate.
Seychelles is planning to kickstart its tourism industry by getting rid of quarantine requirements altogether for incoming visitors who have been fully vaccinated against Covid-19.
The country will be welcoming fully vaccinated visitors from anywhere in the world with immediate effect, although they must still also present a negative Covid PCR test result taken with 72 hours of travel.
There will be no need for quarantine for vaccinated travellers – up until now, visitors had to self-isolate at their hotel for 10 days on arrival.
To be considered as vaccinated, visitors must have received both doses of any of the four main vaccines – Pfizer, AstraZeneca, Moderna and Janssen – and waited two weeks after the second dose for the inoculation to take effect.
As proof, visitors will need to submit an "authentic certificate from their national health authority".
And, from 25 March, unvaccinated travellers can also enter the country without needing to quarantine, providing they present a negative test result.
As of 1 February, all international tourists can enter Georgia (the country, not the US state) as long as they have received both doses of their Covid-19 vaccine and can provide proof.
Georgia is the first country to fully remove entry restrictions for vaccinated passengers - no testing pre-departure, no testing on arrival, and no quarantine.
"As for foreign visitors, they will be able to enter Georgia unconditionally if they submit a full course of any type of covid-vaccine, which means two full doses, if they present a document at the border," according to the country's Ministry of Foreign Affairs.
Since May 2020, Georgia has had an international flight ban in place for most of the world, but this too will be lifted from 1 February, allowing multiple airlines to resume flights.
Romania has announced that travellers who have received both doses of the coronavirus vaccine will not need to quarantine on arrival, effective immediately.
In a document issued earlier this month, the country's National Committee for Emergency Situations (CNSU) announced that people coming from countries or areas of high epidemiological risk, or who have come into direct contact with someone who's tested positive for Covid, are exempt from quarantine measures if they are fully vaccinated.
That means they've had two doses of the vaccine, and at least 10 days have passed since the second dose was administered before arrival into Romania.
Incoming visitors will need to show proof of this through a "document issued by the health unit which administered it, from Romania or from abroad". There's no indication which of the vaccines will be acceptable.
The CNSU said that it's made the decision based on the fact that there's been a downward trend in infections in Romania and that there's a "need to create the necessary socio-economic conditions" to benefit the national economy.
The changes will apply to visitors from the UK, who have up to now been required to quarantine 14 days as well as show evidence of a negative Covid test (either PCR or antigen test accepted) taken within 48 hours of travel.
According to the Icelandic authorities, "all those who present a valid international vaccination certificate for full vaccination with an approved vaccine against Covid-19 are exempt" from the testing and quarantine requirements put in place for all other arrivals.
However, Iceland has stressed that having a vaccination doesn't override the current travel restrictions – only individuals who are already authorised to travel to Iceland may enter the country. Iceland's borders are only open to residents and citizens of EEA countries and Switzerland. Since the end of the Brexit transition period, the UK is considered a "third country" and therefore citizens cannot travel to Iceland – whether vaccinated or not – unless they have a valid exemption, such as having Icelandic family member.
