Brits have been left confused following claims those who've had an Indian-made AstraZeneca Covid vaccine could be locked out of European holidays.
There were claims that up to five million Brits could be barred from holidays in the European Union because their vaccines are not recognised by the bloc's passport scheme.
But the UK government has insisted it is "confident" travel will not be affected as "no Covishield jabs have been administered in the UK".
The claims involve doses of the AstraZeneca vaccine made by the Serum Institute of India - known as Covishield.
Despite it being the same as other AstraZeneca doses, it has not been authorised by Europe's regulator and is therefore not recognised by the EU, a report claimed.

Brits who believe they have had vaccines from the Indian-made batches have spoken of their confusion and disappointment, and said they should have been informed of the situation before being vaccinated.
Kerry Capps told The Mirror she felt "utterly frustrated and disappointed" at the issue.
She said: "I am so disappointed in the government, as they expect the nation to put their trust in them. I believe that the government should have approached the subject themselves and addressed it to the public before anyone was given the dose from the three batches that were made in India.
"Now because I have unfortunately received one of the vaccines from that batch, I am now not able to get the EU Vaccine Certificate currently to allow me to travel to EU countries that are currently permitting people in who have this new certificate.
"I strongly believe that the UK government should have acted more responsible and waited until the Indian made vaccine was covered by the EU certificate.
"When I received my first dose of the AstraZeneca vaccine back in March, I believed that the vaccine I was receiving was going to allow me to travel to countries that are allowing people in with both doses."
She added: "I have a holiday booked for February next year to Fuerteventura and now I feel anxious about if by then I will be eligible to get the new vaccine certificate."
Judi Rudd told The Mirror: "I have had one jab from a batch made in India, my first one. The second one was not from batches made in India.
"I'm wondering how this will affect people wishing to go on holiday to countries not accepting the India batches.
"I haven't booked a holiday but with even more confusion it means I definitely would hesitate to book a holiday now, this is not helping the travel industry, it has been in the news about countries not accepting the Indian batch but nothing mentioning the implications for people who have had one Indian batch jab."
She added that "as usual nothing is clear".
Sadia Nawaz told the Mirror she was concerned because she was counting on a 'vaccine passport'.
"I'm absolutely terrified of what this means," she said.
"How can the government play with the lives of 5 million people without going through rigorous regulations."
Another reader said: "My reason for having the vaccine in the first place was purely for holiday travel and now I find I may be refused because of this.
"I wouldn't have had the vaccination other than this reason so find I have been vaccinated for no reason now as I will be refused access to the EU."
One mum expressed her disappointment over the claims the Indian-made batches did not have the same authorisation as the ones made in the UK. She described it as "worrying".
"If they are the same product, which I believe they are, they should be recognised as such.
"I should have been informed when I had my first jab that it actually hasn't been approved. I should have had the choice to take it or not.
"Me, my husband and two children have a holiday booked in Spain for August.
"We drive through and stop over in France for two nights to get there and to get back, however now it seems even though I'm double jabbed, me and my family cannot go.
"France say they won't recognise this jab, but Spain will."
A spokesperson for the UK government denied claims that Covishield vaccines have been given to Britons.
The spokesperson said: “This is completely untrue - no Covishield vaccines have been administered in the UK.
“All AstraZeneca vaccines given in the UK are the same product and appear on the NHS Covid Pass as Vaxzevria.
"The European Medicines Agency has authorised this vaccine and we’re confident travel will not be affected.
“All doses used in the UK have been subject to rigorous safety and quality checks, including individual batch testing and physical site inspections, by the medicine’s regulator, the MHRA.
“The EU Digital Covid-19 Certificate is currently for EU citizens only, or third country nationals legally staying or resident in the EU.
"Ensuring safe and open travel with our global partners is a clear priority and we are engaging the European Commission on certification.”
The EU is rolling out a Digital Covid Certificate so travellers can prove their vaccination status in order to exempt them from quarantining when crossing an international border.
The EU Digital Covid Certificate, now in operation to allow travel without quarantine, reportedly would not recognise the Indian-made AstraZeneca batch numbers 4120Z001 , 4120Z002 and 4120Z003 which are noted on the NHS app.
Reports say 10 countries have now confirmed they will accept people who have had the Indian-made vaccine batches.
The countries are eight EU states including Greece and Spain, as well as Iceland and Switzerland, The Telegraph reports.
Austria, Germany, Slovenia and Ireland are among the others, Al Jazeera adds.
