The UAE reported 156 new coronavirus cases and 216 recoveries on Wednesday, its lowest daily tally since April 1 last year.
Officials said three people died in the past 24 hours from complications.
The country has recorded 737,229 cases, 730,309 recoveries and 2,107 deaths since the first Covid-19 case was detected in the Emirates on January 29 last year.
Widespread testing and tracing, stringent safety measures and a high vaccination rate have been credited for bringing down daily infections.
Cases have dropped since reaching close to 4,000 a day in January.
An additional 298,908 tests were conducted over the 24-hour period, bringing to 85,810,321 the total number carried out since the beginning of the outbreak.
Meanwhile, the UAE has authorised emergency use of booster shots of Pfizer-BioNTech and Sputnik vaccines for some groups.
Booster shots are to be given six months after the second dose.
The announcement came during the weekly Covid-19 briefing on Tuesday.
The groups that should take a booster shot are senior citizens and residents aged over 60; people with chronic diseases, or at risk of complications (aged 50-59); and people receiving long-term health care (aged 18 years and over).
The announcement does not apply to those who have received Pfizer-BioNTech or Sputnik booster doses after being fully vaccinated with Sinopharm.
The briefing heard that the decision came after studies showed the benefits of a booster six months after the second dose.
