The Sputnik V vaccine might be good. But there’s a fair bit of evidence that it’s mass manufacture has some problems. Which makes it difficult to say with certainty that what’s injected into peoples arms, is effective as what was tested during clinical trials.
One have to admit this is a major anti-vax move being performed by USA and EU.
If the government get to discriminate which vaccines are good and which are not, why their citizens won't do the same, even if they leave the 'good' bucket empty?
When I travelled to South America I had to do "the" vaccine shot (yellow fever I believe), but nobody would inquire me "which one" and whether it is on some white list.
