Russia made the world astonished by announcing the invention of coronavirus vaccine ‘Sputnik-V’. This time, Putin’s country shook the world once again by developing that vaccine as freeze-dried version.
Russia developed the dried form of the vaccine, that does not require freezing, for people in remote areas. It can be sent to remote area by filling in Thermocol boxes, according to Russian researchers.
Meanwhile, the vaccine “Sputnik-V” approved for use in Russia appears safe and triggered immune responses in tested adults, according Lancet.
It said the trials took place in two Russian hospitals and involved 76 healthy adults aged 18 to 60.
Gamaleya’s researchers used two different adenoviruses to get around this problem. Some subjects in their trial were injected with a version of the vaccine using one or the other, and some were injected with both, three weeks apart. Further complicating the results, some were given a frozen version and some were given a freeze-dried version.
The two-dose regimen resulted in the strongest response, similar to findings from early-stage studies of vaccines now in large Phase 3 studies.❐
