Here’s an overview:
From March, Denmark, Austria and Hungary were among the first countries to introduce health passes, either on paper or in digital form.
You still need a pass to go into restaurants, hotels and sports centres in Austria. In Denmark it now only applies to hairdressers and sports centres.
In Hungary, immunity certificates delivered from the first vaccine shot were required to stay in hotels, go to restaurants, theatres, sports or music events. Now they are limited to health centres and gatherings of more than 500 people.
A European Union pass, containing a QR code allowing to check if the bearer is vaccinated or had a recent negative test, came into force on July 1st.
It allows travellers to cross borders of 33 European countries — the 27 EU states and neighbouring Andorra, Iceland, Liechtenstein, Monaco, Norway and Switzerland.
No pass, no shopping
In Portugal, a pass is needed to stay in a hotel or play team sport. It is also required to eat inside restaurants, but only at weekends.
Ireland demands the pass all week long to eat or drink inside pubs and restaurants, while in Luxembourg you need it to go into a shop.
France and Italy join in
In France, the pass has been mandatory since July 21st for cinemas, museums and sports centres which take more than 50 people, despite street protests.
From Monday, it is required for cafes and restaurants, fairs and trade shows, planes, long-distance trains and buses and medical establishments.
A similar green pass came into force in Italy on Friday which will be extended to domestic flights, trains and some ferry services from September 1st.
Teachers and university students will also need it from that date.
OK for brothels
In Germany, where regions decide health policy, some require a pass to enter hotels, cinemas, sport halls and even brothels.
In Spain, which has a similar system, the northern region of Galicia recently became the first to demand the pass to enter bars and restaurants and nightclubs in the hardest-hit places.
Andalusia in the south will extend the pass to nightclubs once courts give it the green light.
NYC and Quebec
New York became the first major US city to introduce a vaccine pass earlier this month when mayor Bill de Blasio said it would be needed for restaurants, gyms and shows.
The law will come into effect on August 16th, but the first checks will not be carried out until September 13th.
On Thursday, Quebec announced it would introduce a vaccine passport, the first in Canada, for all non-essential activities.
Israel re-instated its green pass programme at the beginning of August, restricting access to gatherings of more than 100 to people who have been vaccinated, recovered or tested negative less than 72 hours previously.
From August 8th unvaccinated people will have to present a test carried out less than 24 hours before, with a pass required for children younger than 12 from August 20th.
