DUBAI: Bahraini authorities have authorised the use of a booster dose of the Sputnik V COVID-19 vaccine, the first time the Russian shot has been approved for a third dose, the state-run Bahrain News Agency said on Saturday.

The booster shot was approved for use among all over-18s at least six months after receiving their second dose of the Sputnik V vaccine, the news agency reported.

Bahrain and fellow Gulf state the United Arab Emirates have already approved third booster shots using the Pfizer-BioNTech vaccine.

The small island nation's COVID-19 infections are decreasing, currently at 3% of their peak with 95 new infections reported on average each day, according to the Reuters COVID-19 Tracker.
