Scots holidaymakers will face new travel restrictions unless they are triple-jabbed, as some countries tighten Covid entry rules.
Jet-setters who do not receive their booster jabs may be unable to visit two countries from this week.
Austria and Israel have now implemented time limit rules that determine whether a person will be allowed to enter the country.
The timing of a person's vaccination will now reflect the validity of their status, according to the tougher rules.
The two countries are leading the way with the new entry requirement, with other countries possibly following suit.
Israel has the harshest rules, only allowing holidaymakers to enter if their latest jab was within 180 days.
You can enter Israel if you have “received a booster dose and at least 14 days have passed by the day of entry,” the rules state.
The new restrictions go even further with Israel barring foreigners if the date they are set to leave the country falling more than 180 after their second or booster dose.
However, the rules also state that Israel will allow travellers with proof of Covid recovery within the period of 190 days to visit.
Austrians rules are slightly less strict with travellers being categorised as unvaccinated if it has been longer than 360 days since their second or booster dose.
This then means that a PCR test will be required for entry.
