Russia said today that their main vaccine, Sputnik V, did not cause rare reports of blood clots after using two other vaccines designed with the same technology.
The Gamaleya Institute, which developed the vaccine, said: “A complete analysis of adverse reactions during clinical trials and mass vaccination with Sputnik V showed that there were no cases of cerebral venous thrombosis.”
It is currently suspected that AstraZeneca and Johnson & Johnson vaccines have caused dozens of such extremely rare cases of blood clots, some of which have died, so the authorities in some countries have restricted their use.
Both vaccines and Sputnik V use the same production technology. However, the Gamaleya Institute emphasized that all vector vaccines are different and cannot be directly compared. According to the source, the artificial satellite is very different from AstraZeneca and Johnson & Johnson in structure and production technology.
