So the EU has quality standards to ensure the safety and efficacy of drugs/vaccines. Companies A,B,C, and D all went through the safety trials and quality tests to get approval. Company E did not engage in the safety trials and efficacy tests to gain approval.Those that received vaccines that the EU does not consider 'valid' and therefore get treated differently to those who received a EU approved vaccine.
Country A decides to buy Company E's vaccine, knowing full well that their vaccine has not met approval of EU quality standards.
Seems to me that Company E didn't act responsibly by producing a vaccine without adequate safety/efficacy trials and County A was pretty dumb for opting to buy the non-approved vaccine.
Your complaint should be lodged with the Gamaleya Reseach Institute or with the government of Argentina.
Suggesting that the problem is an issue of discrimination -presumable on the part of the EU-is just silly.
But then again, we live in age where modern medicine, drugs, and vaccines have reduced infant mortality dramatically over the past 100 years. This has diminished the Darwinian process of weeding out the weak and the stupid. So now we left with a society populated with low IQ idiots who scream 'discrimination' at the very entities that enabled them to survive in the first place.
Well done humanity.
