A string of European countries have announced they are waiving Covid travel restrictions to welcome jabbed Brits this summer.
Germany, Spain, the Netherlands and Switzerland became the latest nations to ease restrictions on foreign visitors who have had both doses.
Vaccinated travellers will be able to enter the countries without having to do a PCR test or go into quarantine.
Germany said yesterday it is even allowing people from higher risk "amber" nations and all will be exempt from having to self-isolate on arrival, while those requiring a test to enter will be given one for free.
Spain and the Netherlands, meanwhile, are allowing anyone from countries with low infection rates and they don't even have to prove vaccination status.
The former is considering a 50 or 100 per 100,000 case rate threshold, while the later has set theirs at 150, which would include the UK.
Switzerland is also dropping quarantine for jabbed people from "safe" countries.

In contrast, Britain requires anyone from just 12 green-listed countries to take a test on or before the second day of arrival, even if they've been vaccinated.
Those include Portugal, Israel, Gibraltar and Iceland.
It comes after Portugal announced Brits would be allowed to enter the country from Monday when the borders re-open following hours of uncertainty.
Anyone coming to the UK from an amber listed country, which includes Spain, Germany, Switzerland and Holland, as well as France and Greece, must quarantine for 10 days and have two PCR tests after two and then eight days.
As such, the UK has been criticised for being too cautious, despite the threat being posed by the Indian variant.
Johan Lundgren, chief executive of easyJet, said tougher rules meant "not only are Brits going to be beaten to the sun loungers by the Germans, Dutch and Swiss but this will leave them picking up a bigger bill for their holiday, coupled with an onerous, expensive and unnecessary testing regime for low-risk countries".
"We don't want Britons to be left behind in the race to the sun when the huge success of our vaccination programme does mean travel can safely reopen," he added.
Tim Alderslade, of Airlines UK, said: "The UK will rapidly fall behind the rest of Europe unless it looks again at its overly cautious approach to international travel.
"There is no reason why our green list can't be expanded to include the US and the most popular European hotspots, or for the UK not to follow the EU's lead in exempting vaccinated travellers from restrictions."
There are fears that the B1.617.2 strain will hinder the UK's pandemic recovery and could lead to the final lifting of restrictions on June 21 being postponed.
As experts say vaccines have saved 12,000 lives, a surge in cases in Bolton threatens to scupper progress.
Scientists and government figures are holding urgent talks amid fears it could delay the end of lockdown rules.
Boris Johnson today said he was "anxious" about the B1.617.2 strain, which almost tripled in a week to 520 UK cases as of May 5.
