Rules in Abu Dhabi stipulating that only those who have been vaccinated can gain access to most public places have come into effect.
The Covid-19 safety regulations started on Friday and are designed to curb the spread of the virus and safeguard public health.
Under the measures, which apply to citizens, residents and tourists, proof of vaccination will be required to visit most venues, including malls, restaurants and cafes.
The rules also apply to gyms, sporting activities, spas, entertainment centres, and all other retail outlets, except supermarkets and pharmacies.
People must also be vaccinated to visit museums, cultural centres, universities, institutes, schools and nurseries in the emirate.
Al Hosn, the UAE's testing and vaccination app, will act as the pass to secure entry.
People must also have a green status on the app to gain access to those facilities. The green status is achieved through a negative PCR test and remains valid for 30 days.
Entry is also allowed for those exempted from vaccination with a green status on Al Hosn, which appears after a negative PCR test result and remains for seven days.
Children under 16, whose status will appear as green on the Al Hosn app without the requirement of a test, will also be allowed entry.
Unvaccinated people and those with a grey status on the Al Hosn app, which reflects an expired PCR test, are prohibited from entering these public places.
The measures came a day after Abu Dhabi announced that the nightly stay-home orders were to end.
The restrictions under the National Sterilisation Programme ran from midnight to 5am and have been in place since July.
The Abu Dhabi Emergency, Crisis and Disasters Committee said the programme had achieved its objective.
Cases have been falling across the UAE over the past few weeks.
The country recorded 1,077 cases on Wednesday, its lowest daily figure this year.
Mass testing and one of the world's fastest vaccination campaigns have helped the UAE curb the pandemic.
