You’re just proving how little your critical thinking and common sense is worth. My guy… Modern vaccines as injections are only around 100 years old. 30 years is a third to a fourth of that time. That isnt relatively new. 30 years is an eternity.
Sars cov 1 is a thing that was succesfully vaccinated against and sars cov 2 is a variant that shares many things with 1.
I also asked you what sources you have that support your argument that vaccines need a 3rd trial.
You answer was “it came to me in a dream/i pulled it out of my ass” you have the wit of a sockhamster.
Billions of people have the vaccine and a booster. It’s been more than 3 years. No long term negatives. You’re just dumb and contrarian for the sake of it.
