It can be administered six months after an individual receives the second dose of any other vaccine against Covid-19 in the country.

The single-component Sputnik Light vaccine was approved for use by the UAE in October.

It is based on human adenovirus serotype 26, Sputnik V Covid-19 vaccine’s first component.

The two-dose Sputnik V vaccine was also authorised by the UAE’s MOHAP in January.

RDIF claimed that the single-dose vaccine is highly effective when used as a booster and on a standalone basis.

According to the data gathered by the Gamaleya Center from 28,000 subjects in Moscow, the Sputnik Light vaccine showed an efficacy of 70% when administered standalone during the initial three months after vaccination against the Delta variant of Covid-19.

It is also 75% effective among participants aged below 60 years.

RDIF noted that Sputnik Light’s efficacy as a booster shot for other vaccines against the Delta variant will be similar to the efficacy of the Sputnik V vaccine against the variant, more than 94% against hospitalisation and 83% for infection.

RDIF said in a statement: “Sputnik Light has been proven to be safe and highly effective by real-world vaccination data. In particular, the vaccine has demonstrated an efficacy of between 78.6% to 83.7% among the elderly as confirmed by the Ministry of Health of Buenos Aires, Argentina.

“Paraguay’s Ministry of Health also found Sputnik Light to be 93.5% effective during the country’s ongoing vaccination campaign.”
