Sputnik V
The Sputnik V vaccine is named after the world's first artificial satellite, the iconic Soviet-era "Sputnik 1", which was launched into low Earth orbit in October 1957 – it burned up three months later when its batteries died. Its namesake was developed by the Gamaleya Research Institute of Epidemiology and Microbiology in Moscow, Russia.
Any time Russia or the USSR are mentioned there needs to be some added slight in the text.
Is this meant to hint something about the vaccine? Or just about Russian manufacturing.
It's not single shot and the fact that it isn't mRNA is a detriment. No vaccine has many severe side effects, and they're so infrequent that it's hard to figure out which one has less. The cheaper part is the best part about it. It's still a top tier vaccine but so far I think Moderna is on top given that they have already made a booster for the South Africa mutation.
