If it's been more than nine months since your second jab, you may need a booster before heading to Europe.
The European Union recently proposed an 'expiration date' of nine months for visitors' Covid-19 vaccination passports.
A booster shot would become necessary for travellers to extend the validity of their EU Digital COVID Certificate.
The proposal would be part of an attempt to quell the recent wave of coronavirus cases that have prompted several countries to return to lockdown.
Speaking on Thursday, European Commissioner Didier Reynders said it was important to stay vigilant in how they managed the pandemic. "It is evident that the pandemic is not yet over," he said.
