A small number of people in the UAE have received a third Covid-19 vaccine "booster" shot that aims to prompt an immune response against the virus.
Dr Farida Al Hosani, spokeswoman for the country's health sector, said vaccinated residents and Emiratis who did not develop antibodies against Covid-19 could take a third dose of the Sinopharm vaccine.
"Some people received a third dose of the Sinopharm Covid-19 vaccine, but the number is very minimal compared to those who received doses one and two," Dr Al Hosani told The National.
The vaccine is available for free across the country and is administered up to 28 days apart.
Tests in the UAE suggested it was 86 per cent effective against preventing infection, although the maker revised the figure to 79.34 per cent after it received more data.
Its effectiveness kicks in up to 28 days after the second dose.
More than 6.3 million doses of Covid-19 vaccines have been administered across the country.
Most are Sinopharm doses, but it also includes Pfizer-BioNTech, Oxford-AstraZeneca and Sputnik, each of which have been approved for local use to some degree.

A few people have reported being unable to receive the second vaccine. Why is that? Will the vaccine be as effective if they are delayed in receiving their second shot?
All vaccination centres were told to give priority to the elderly, above people with chronic conditions and people with disabilities, while also administering the second dose for eligible individuals.
It is highly recommended to take the second dose 21 to 28 days after the first.
However, if a delay is unavoidable, taking the second dose beyond the recommended time interval will still be effective.
How will authorities resolve the issue of demand for vaccines outstripping supply?
At this stage, health authorities are giving the priority to specific, vulnerable groups in addition to all people eligible for the second dose.
It is important to highlight that the UAE is one of the leading countries around the world in securing supplies of Covid-19 vaccine for their population.
Due to collaborative efforts of the health sector and the commitment of the UAE community, vaccination coverage in the UAE is by far the fastest in the world.
