Sputnik vaccine more effective against Omicron than Pfizer/BioNTech

While Western Europe and the USA reported a new record every day in the number of cases due to the Omicron variant of the Corona virus, a new research was published by Russian and Italian scientists. The research revealed that the Russian-made Sputnik V vaccine provides more protection against Omicron than Pfizer/BioNtech.

Scientists from the Spallanzani Institute in Italy and the Gamaleya Institute in Moscow, which also developed the Sputnik V vaccine, signed a new study.

Accordingly, it was determined that the neutralizing antibody levels provided by the Russian origin Sputnik V vaccine were effective for a longer period of time than the Pfizer vaccine.

According to Reuters, the Russian-Italian study compared the blood serum of people with different vaccines.


The researchers found that in samples taken three and six months after the second dose of vaccine, the antibody levels in patients who received two doses of Sputnik V were more resistant to Omicron than those vaccinated with Pfizer/BioNTech.

Preliminary study results, published Jan. 19, also revealed the need for a third dose of vaccine.

The study detected Omicron-specific neutralizing antibodies in the blood serum of 74.2% of people vaccinated with Sputnik and 56.9% of people vaccinated with Pfizer/BioNtech.


An earlier preliminary study by the Gamaleya Institute, the developer of Sputnik V, had found that one booster shot of the Sputnik Light vaccine produced a stronger antibody response to Omicron than the two-dose Sputnik V vaccine alone.

On the other hand, the Omicron variant of the corona virus continues to show its effect all over the world. Case numbers have broken a record in parts of the US and Western Europe.

While there has been an increase in the number of cases in Russia, Russia has announced that they have 1,600 Omicron cases so far.
