COVID-19 Crisis: Joint study reveals that Sputnik V demonstrates 97% efficacy against Omicron-caused hospitalization following revaccination with Sputnik Light or Sputnik V

Recently, a study (involving Russian scientists including representatives of the City Clinical Hospital No. 67 and the Gamaleya National Research Center of Epidemiology and Microbiology) revealed that the Russian vaccine Sputnik V demonstrated 97% efficacy against hospitalization caused by the Omicron variant following revaccination with Sputnik Light or Sputnik V, according to a press release published online.

To put things in perspective, posted below is the excerpt from the press release published by Some parts in boldface…

The Gamaleya National Research Center of Epidemiology and Microbiology (Gamaleya Center) today announced that Vaccines, the leading peer-reviewed medical journal, has published the results of a joint study conducted by team of scientists including representatives of Moscow’s City Clinical Hospital No. 67 named after L.A. Vorokhobov and the Gamaleya Center showing the two-dose Sputnik V vaccine is 97% effective against hospitalisation caused by the Omicron variant of coronavirus (B.1.1.529) among those vaccinated with 3 or 4 components (re-vaccination with Sputnik Light or Sputnik V after Sputnik V).

The corresponding article has been peer-reviewed and is available at:

The study was conducted from 11 January to 21 February 2022 involving over 1,000 patients in Moscow. Sputnik V showed high efficacy against hospitalisation at 85.9% among patients vaccinated with at least one component. Efficacy among those vaccinated with 3 or 4 components (re-vaccination with Sputnik Light or Sputnik V after Sputnik V) rose to:

o   97% against any cases of hospitalisation;

o   97.7% against moderate-severe and more severe cases;

o   98.6% against severe and critical cases;

o   99.4% against critical cases.

As authors note, “the study shows that vaccination with Sputnik V and Sputnik Light has a high effectiveness for protection against hospitalisation. The reduction in the severity of COVID-19 regarding the Omicron variant was also observed. The greatest effectiveness was evident in protection against a critical course of the disease requiring patients to be admitted to the intensive care unit.”

While it is very difficult to talk about Russia-related matters due to the ongoing Russia-Ukraine war (note: help the people of Ukraine by donating through Hillsong Church online), it is important to focus on what Sputnik vaccines are able to do as the whole world continues to struggle to bounce back from the COVID-19 crisis economically, socially and medically. With regards to my native Philippines, the daily count of new COVID-19 infections has gone up nationwide in recent times. The Metro Manila cities of Muntinlupa and Pasig each had their own shares of increased new COVID-19 infections.

I can only hope that the incoming administration of President-elect Ferdinand “Bongbong” Marcos, Jr., will consider acquiring more doses of Sputnik V and Sputnik Light even though the national authorities are trying to balance supply of COVID-19 vaccines with the rather slugging public response in terms of getting vaccinated or boosted at their local vaccination sites. The formulation behind Sputnik V and Sputnik Light should be strongly considered when it comes to immunizing as many Filipinos as possible from COVID-19, including the more infectious Omicron variant and its sub-variants.  

Let me end this piece by asking you readers: What do you think about this new development? Have you ever been vaccinated or boosted with a Sputnik vaccine? Did you receive at least two doses of Sputnik V already? Does your local vaccination site have Sputnik V or Sputnik Light in supply right now? Did anyone from the anti-vaccine fanatics community turn violent against you because you refused to believe in them?
