Having both doses of your vaccine has fast become the norm for bypassing quarantine and even a Covid test before travel. And yet, just as things are beginning to gain a semblance of normality, a handful of countries are now tightening their travel restrictions by putting an expiry date on vaccine validity.

This new trend began with Croatia, which updated its entry requirements in July 2021. Austria followed suit in August, and now Israel and Switzerland have both introduced similar restrictions. And as more countries weigh up whether their own citizens will require a booster jab, it’s feasible that the trend will continue to snowball. Here’s what you need to know.
