Russia’s lack of Sputnik V means that the second dose is restricted

Mexico City – Russian officials say Russia may not be able to supply enough to those who have already received the first dose because of the many problems with the second dose of the Sputnik V coronavirus vaccine. Said on Monday.

This is the latest explanation of the production problem of Sputnik V, which the Russian government has promised to other countries but has not been able to supply enough.

Sputnik is one of the rare coronavirus vaccines in that the two doses are different and incompatible.

Russian vaccines use a modified version of the common cold-causing adenovirus as a way to stimulate the body to react in the event of COVID-19, using the gene for the coronavirus peplomer. I will carry it.

This is a technology similar to the vaccine developed by AstraZeneca and the University of Oxford. However, unlike AstraZeneca’s double-dose vaccine, the Russian approach uses a slightly different adenovirus for the second boost.


Hugo Lopez Gatel, assistant health minister of Mexico, said Russians have found that the first adenovirus grows much faster than the second adenovirus.

Lopez Gatel suggested that Russian scientists now give up the idea of ​​giving two separate Sputnik V shots every few weeks and instead give them a second booster shot six months later. Said that.

“In the months, the amount of the first dose they managed to produce no longer matched the amount of the second dose they could produce,” López-Gatell said.

To date, Mexico has received only 1.9 million Sputnik V doses out of a total of 24 million contracts. They have been forced to rely more on the Pfizer vaccine, of which 10.6 million have been vaccinated and about 10 million of the two Chinese vaccines have been vaccinated. We also vaccinated AstraZeneca about 4.6 million times.

Mexico has recorded deaths from COVID-19 confirmed in more than 219,000 tests, but the government itself currently estimates about 347,000 deaths, as the country rarely tests.


This is the latest in a series of setbacks against Russian vaccines.

In April, Slovak regulators said they could not assess the benefits and risks of not receiving sufficient information from producers about the Sputnik vaccine.

The Slovak State Drug Management Institute said that about 80% of the requested data was not provided. According to a study published in the medical journal The Lancet, the vaccine delivered to Slovakia was different from the original double-dose Sputnik V vaccine, which is believed to be 91% effective.

The official Twitter account for the Sputnik V vaccine claimed that Slovak drug regulators “launched a disinformation campaign against Sputnik V.”

Also in April, Brazilian health regulators cited safety concerns while rejecting several state requests for nearly 30 million imports of Sputnik.

Russia is aggressively selling Sputnik V overseas, despite its relatively slow domestic expansion and limited production capacity. Dozens of countries have approved the use of Sputnik V, and many have signed contracts with the Russian Direct Investment Fund to bankroll vaccines and obtain shot shipments.
