Brit holidaymakers are risking being barred from entry to some countries for another month.
And it is all to do with their vaccine jabs and whether or not they have had ones made in India.
Brit tourists with certain batch numbers on their AZ vaccine jabs could be denied entry to some European Union nations.

One couple was barred from a flight to Malta earlier this week.
They had hoped to travel from Manchester Airport but were turned away from flying due to their Indian-made jabs.
According to The Telegraph, the SII believes it will take weeks to resolve the issue with the EU.
Grant Shapps had said the Government would confront Malta earlier on Wednesday after reports it was turning away people vaccinated with the Indian-made jab.
The problem centred on doses made by the Serum Institute of India, known as Covishield.
Despite the jab being the same as other AstraZeneca vaccines, it has not been authorised by Europe’s regulator and is therefore not recognised by the EU.
Mr Shapps later tweeted: “The Maltese authorities have amended their travel advice so anyone who has an Oxford/AstraZeneca vaccine in the UK (regardless of manufacture location) is able to travel without being turned away – with all vaccines having gone through rigorous safety and quality checks.”
Earlier on Wednesday, Mr Shapps told BBC Breakfast: “The (UK) medicines agency, the Medicines and Healthcare products Regulatory Agency, have been very clear that it doesn’t matter whether the AstraZeneca you have is made here or the Serum Institute in India.
“It is absolutely the same product, it provides exactly the same levels of protection from the virus.”
