I don't know what you consider the "whole official process" but it exists for good reasons.
Yeast-based vaccines seem cool, and ingestion based vaccines rather than injection increases the availability, but also counterfits. But as someone said in the article. You cannot draw conclusions from two test subjects.
Does it make pregnant women miscarry? Does it make them sterrile? How does it affect those with different blood types? how does it interact with other types of commonly taken medications? Or even food for that matter.
Don't you think it would be good to know those things ahead of time? Because that's what the "whole official process" is about.
