Sputnik V vaccine effective against all COVID-19 variants, expert claims

Sputnik V is one of the only three COVID-19 vaccines in the world that has an efficacy rate of over 90 percent.

A study from Gamaleya Institute found that Sputnik V is “highly effective” in neutralizing the Delta variant. This comes after officials learned that the strain is “more transmissible” than other COVID-19 variants.

While vaccines continue to roll out across the globe, the worries over the said variant remain apparent. There are even talks of whether the current jabs are effective in protecting individuals against all variants of the coronavirus.

As this dynamic goes on, a Russian microbiologist recently assured the public that the vaccines from The Gamaleya National Center of Epidemiology and Microbiology can do the job. Alexander Gintsburg stated that Sputnik “protects a person from all [COVID-19] variants,” according to Republic World.

Vaccinating with Sputnik V

Earlier this week, the Head of the Gamaleya Center released a statement about the matter. He attested that their vaccine is effective against “all variants of COVID-19 known today,” including Alpha and Delta.

The publication, later on, recalled that Sputnik V is one of three vaccines to have over 90 percent of efficacy against COVID-19. The other two are vaccines from Pfizer-BioNTech and Moderna.

Apart from protection against all variants, they also found that the Russian vaccine can neutralize the “aggressive” Delta variant. Following the study, RFID and the vaccine developer said that they will soon offer “booster doses” against the COVID-19 strain to other vaccine makers.

It uses two different adenoviruses

The Gamaleya National Center of Epidemiology and Microbiology in Moscow, Russia developed Sputnik V. It also carries the name “Gam-COVID-Vac.” To date, over 68 countries have authorized the use of the Russian-made vaccine.

Medical News Today said that it uses two adenoviruses as viral vectors. Gamaleya previously reportedly noted that using different vectors for two shots will result in higher efficacy. This is in comparison with vaccines that use the same vector for two doses.

The first jab contains the Ad26 or adenovirus 26, while the second shot has the Ad5 or adenovirus 5. There is an interval of 21 days when receiving the two doses.

The safest among all COVID-19 vaccines

On Thursday, a study from the Buenos Aires Ministry of Health confirmed that Sputnik V is the “safest among all COVID-19 vaccines” in the province of Argentina. As noted, there are no records of death related to the vaccination.

Alongside this, the “post-vaccination events” were mild. Sputnik V has a 0.7 Events Supposedly Attributable to Vaccine or Immunization (ESAVI) rating, while Sinopharm and AstraZeneca have 0.8 and 3.2, respectively.
