Sputnik Light vaccination could complement Pfizer’s use

Pfizer has a problem with the Delta strain, which now represents 90 percent, and in some regions of the world even 100 percent of total infections by the SARS-CoV-2 coronavirus, the scientist said in statements to the TASS news agency.

He noted that the effectiveness of the US drug ‘has been reduced by half, almost to 50-40 percent, which is not observed in Sputnik V, so the proposal of the Russian Direct Investment Fund (RDIF) is quite logical and it has scientific bases.’

On August 11th, the RDIF launched the proposal to use Sputnik Light in the third doses for those vaccinated with Pfizer. Also last autumn, RDIF proposed, in particular, cooperation with the British-Swedish company AstraZeneca.

They reported that Pfizer’s effectiveness dropped from 76 percent to 42 percent owing to the widespread prevalence of the Delta strain.

The Russian Health Ministry explained earlier that the effectiveness of Sputnik V against this strain is 83 percent. Sputnik Light is the first component of this vaccine.
