While it is nice to know that my native Philippines has secured over two hundred million doses of COVID-19 vaccines and the vaccination operations around the country include the issuance of booster shots, I honestly believe that more Sputnik vaccines (Sputnik V, Sputnik Light and the upcoming new Sputnik vaccine designed with Omicron in mind) are needed in the country and more of them should be secured especially since the Omicron variant is infecting more people locally.
In 2021, the Philippines received millions of Sputnik V vaccines but too little of the single-dose Sputnik Light. Good thing that the Philippines will negotiate for more Sputnik Light vaccines because in recent news, Sputnik Light has been approved in Tunisia as a universal booster!
To put things in perspective, posted below is the excerpt from the SputnikVaccine.com press release. Some parts in boldface…
Moscow, December 29, 2021 – The Russian Direct Investment Fund (RDIF, Russia’s sovereign wealth fund) announces the approval of the Russian one-shot Sputnik Light vaccine against coronavirus as a universal booster shot by Tunisia’s Ministry of Health.
Sputnik Light is based on recombinant human adenovirus serotype number 26 (the first component of Sputnik V). A one-shot vaccination regimen of Sputnik Light provides for ease of administration and helps to increase efficacy and duration of other vaccines when used as a booster shot. Sputnik Light has already been authorized in more than 30 countries.
Clinical studies and the real-world data in many countries have demonstrated that Sputnik Light is a safe and effective vaccine when used both on a standalone basis and as a booster.
A study in Argentina on heterogeneous regimens combining Sputnik Light and vaccines produced by AstraZeneca, Sinopharm, Moderna and Cansino has demonstrated that Sputnik Light is an effective universal booster. Each “vaccine cocktail” combination with Sputnik Light provided higher antibody titer on 14th day after administering the second dose as compared to original homogenous (same vaccine as first and second dose) regimens of each of the vaccines.
A preliminary study of the Gamaleya Center has found Sputnik Light significantly increases virus neutralizing activity against Omicron based on sera 2-3 months after revaccination with 100% of individuals revaccinated with Sputnik Light as a booster having developed neutralizing antibodies against this variant. Sputnik Light booster is recommended to strengthen efficacy of vaccines against Omicron. Boosting by Sputnik Light can strengthen and lengthen the quickly waning efficacy of many vaccines in light of combined Delta and Omicron challenge.
Sputnik Light efficacy data:
- Sputnik Light has been proven to be safe and highly effective by real-world vaccination data. In particular, data from the Ministry of Health of Buenos Aires (Argentina) has demonstrated standalone efficacy of Sputnik Light between 78.6-83.7% among the elderly (over 40,000 people of 60-79 years old), which is higher than that of many two-dose vaccines.
- Findings by the Gamaleya Center based on data collected in Moscow have demonstrated Sputnik Light vaccine administered standalone has 70% efficacy against infection from the Delta variant of coronavirus during the first three months after vaccination. The vaccine is 75% effective among subjects under the age of 60. Sputnik V and Sputnik Light are based on a safe and effective human adenoviral vector platform and have not been associated with rare serious adverse events following vaccination, such as myocarditis or pericarditis.
Previously, it has been declared that Sputnik V and Sputnik Light are highly effective against the Omicron variant (referencing an article published in Vaccines medical journal and international real-world data from numerous countries) and Gamaleya itself conducted a preliminary study confirming the findings.
As for the Omicron variant situation here in the Philippines, Sputnik vaccines would be more crucial for public health especially since there are many Filipinos who have been vaccinated with the Sinovac vaccine which according to a recent study was found to be weaker versus Omicron. Once the Sinovac protection has faded away, there is the potential of a wave of new COVID-19 infections caused by the Omicron variant. Right now, we can only hope that the Philippines is negotiating with their counterparts in Russia to acquire many millions of new doses of Sputnik V, Sputnik Light and the upcoming new Sputnik (designed with Omicron in mind).
Let me end this piece by asking you readers: Have you been vaccinated previously with Sputnik V or Sputnik Light? If you were fully vaccinated with Sinovac, do you prefer a Sputnik vaccine to be your booster shot?
