Abu Dhabi, the capital of the United Arab Emirates (UAE), is offering tourists free Covid-19 vaccinations that were previously restricted to UAE citizens and residency visa holders.

There is no indication that the change applies to Dubai, the most populous emirate, or the other five emirates that make up the UAE.

Visitors with visas issued by Abu Dhabi and passport holders eligible for tourist visas when they arrive in the UAE through Abu Dhabi can book free vaccines, according to information provided by the Abu Dhabi Health Services Company (SEHA), which operates the emirate's public health infrastructure.

Holders of expired residency or entry visas are also eligible for free vaccinations, Abu Dhabi Media Office said on June 11.

Job losses and travel restrictions during the pandemic mean some people's residency visas have expired or have been cancelled when they were made redundant.

UAE Health authorities said this month nearly 85 per cent of the eligible population had received at least one vaccine dose, but did not say how many had had two doses.

Infections have risen in the UAE in the past month, and Abu Dhabi still has restrictions on entry, including home quarantine and PCR testing at intervals after arrival. People driving from other emirates are tested to show they are not infected.

Travellers from 27 countries including China, Germany and the United States can enter without quarantine on arrival.

SEHA offers Covid-19 vaccines by China's state-owned drugmaker Sinopharm and by Pfizer/BioNTech in Abu Dhabi.

Dubai Media Office did not immediately respond to a request for comment on whether eligibility criteria was to change. Dubai Health Authority information says vaccines are given only to citizens and holders of valid Dubai residency visas.
